Introduction
This description, however, is far from sufficient to tell
you that those four users can easily be situated up to
300m (980 feet) from the unit, using User Station (U S)
extenders. It also does not tell you that, thanks to our
unique CAM (Computer Access Module) technology,
the host systems can themselves be up to 50m (160
feet) from the unit. In both cases CATx structured
cabling provides neat, easy-to-manage and cost
The MC5-IP variants introduce true global control for
the multiple host systems. Up to four global users can
share access to a computer from anywhere via an IP
network/internet connection using a Real VNC client
application. A modem/ISDN port provides an alternative
backup connection should the network link suffer a
failure. Optional power switch control allows you to
remotely perform a hard reset on any host system, no
matter how badly it has locked up. Finally, to ensure
that only authorised operators are given such power,
the MC5-IP units feature enterprise grade security.
Thank you for choosing the MC5 series from LINDY.
Each of the four models have been designed to take full
advantage of CATx structured cabling (where x means
category 5, 5e or 6) to provide high quality linking plus
ultimate flexibility for installers and operators alike.
At its heart the MC5 is a tried and trusted digital KVM
+ audio switch with 24 ports. In its simplest form, the
MC5 allows up to four users to maintain full control
over multiple host systems.

units you can easily control up to 512 host computers.

How cascade connections operate
The method for cascading MC5 units is straightforward and
requires no hardware settings or lengthy configuration process.
them to locate each other and share information.
The method of linking MC5 units is the same regardless of the
cascade level, or number of devices attached. Put simply:
• A single cascade link is made by connecting a COMPUTER
CONNECTIONS socket of one unit to a CATx USER PORTS
socket of the unit below it.
Port boundaries and numbering for triple link groups
(sixteen port models use groups 31 to 35 only)
Such a single link would allow just one user from the higher MC5
unit to access any of the computer systems attached to the lower
one. However, a single link can cause a bottleneck for multi-user
systems and cause port numbering problems, so the minimum
permissible group link between MC5 units is a triple (quad cascade
links are recommended). These allow three or four users to
simultaneously access computer systems situated anywhere within
the cascade tree.
When triple or quad cascade links are made between units,
each MC5 will automatically recognise the links and treat them
accordingly. The links within a triple or quad group will then be
allocated to users according to their general availability in that
group, not as specific individual lines. To do this, each link group
has an access number, which is determined by the ports to which
they are connected on the switch.
Port boundaries and numbering for quad link groups
(sixteen port models use groups 41 to 44 only)
For instance, a quad group connected to computer ports 1, 2, 3
and 4 of an MC5 unit would always be known as 41, the next
quad group connected to ports 5 to 8 would always carry the
number 42, and so on. The diagram here summarises the ports to
which triple and quad groups must be connected and the resulting
group numbers attained in the positions here
ð
The central purpose of the link group system is that each user can
use a unique address to locate a particular computer. However, as
with the Internet, the route to get there could be slightly different
each time. This avoids any route blocking that could easily be
caused by other users occupying any specific link lines.
Note: Triple and quad link groups may be mixed on one unit
providing the differing link groups lie within appropriate port
boundaries shown opposite - see Tips for successful cascading
for more details.

Each cascade level requires two digits, hence the computer
marked in red requires a unique address with six digits because
it is at cascade level 3, compared to the blue computer at level 2
with its four digit unique address. A computer connected directly
to the MC5 at the top level would simply have a two digit port
number.

• The number of links between units (three or four) determines the number of
users that can simultaneously access the computers situated further down
the tree. Link groups of one and two links should not be used.
• Ensure that cascade links (within a group) between units are approximately
the same length.
• Triple and quad link groups may be mixed on one unit providing the
links lie within the appropriate port boundaries designated in the Group
• MC5-IP models can only be used at the top level of the cascade tree

• For each cascade link, use a standard category 5, 5e or 6 twisted-pair cable,
terminated at each end with an RJ45 connector. There must be no crossover
connections within the cable, i.e. do not use patch cables. The cascade
link cables can be up to 50m (160 feet) in length. However, remember
that the overall length between any remote user (via a User Station) and
any computer (via a CAM) must not exceed 300m (980 feet) - that figure
includes the cascade link cables. Ensure that each of the links within a
cascade group all conform to the same length.

Using cascaded computers
In use, cascaded computers can be accessed using exactly the same methods
as for those connected directly to the MC5. However, by far the easiest way is
to use the on screen menu. This is because it displays the computer names and
does not require any knowledge of port addresses, some of which (as discussed
above) can be up to six digits long. See the Selecting cascaded computers
section in the Operation chapter for more details.
Testing specific links to cascaded computers
As mentioned previously, the best and most efficient way to access cascaded
computers is by using the on screen menu and via non-specific routes through
the link groups. However, during configuration or troubleshooting, it may be
useful to test specific routes to computers in order to verify the various strands
of each link group. By using specific port addresses for each unit, rather than
link group numbers, you can precisely navigate a route through any part of the
system.

Synchronised operation is useful for applications
that require multiple video signals to be switched

where each computer is fitted with multiple video
cards or video cards with multiple video heads.
Whenever an MC5 channel is switched, it sends an

Configuration
Almost all configuration and operational aspects of the MC5 units are controlled
Overall initial configuration
When setting up a new installation, the following stages are recommended:
With security disabled (default setting), all users attached to the MC5 have
full and unrestricted access to all computers and all MC5 settings. In larger
installations, you are strongly recommended to enable security and set up
individual user accounts with access privileges.
All MC5 units have a fixed user account that cannot be deleted, named
ADMIN. This user account is the only one that is able to make important
system changes. If you intend to use security, then it is important to allocate
a password to the ADMIN account.
Use the ADMIN account to add user profiles, passwords and access rights
for each of the system users.
When numerous computers are attached, you are strongly advised to
provide names for each, to assist with recognition.
The long cable links that are possible between the MC5 unit and the
computers and also to the remote users can affect the quality of the video
images displayed. Use the in-built compensation features to eliminate any
potential video image degradation.
Use the ADMIN account to determine key MC5 settings and timing
characteristics.
MC5-IP models only. IP models possess a further collection of IP-related
configuration options and encryption features that protect the installation
from unauthorised global users - ensure that the IP security features are
enabled before connecting the MC5-IP unit to the network. The IP settings
use the standard ADMIN password.

Video compensation
It is important to note that, providing the cabling arrangements do not change,
the various video compensations need to be applied only once to each computer
or remote user link. During operation, control of video compensation is fully
automatic. Please take into account the following when configuring links:
The MC5 units allow computer systems to be placed up to 50m (160 feet) away
and remote users to be extended by a maximum of 300m (980 feet). Such long
cable lengths can affect video signals, especially when higher screen resolutions
are used. In order to eliminate any video signal degradation, all MC5 units and
accompanying User Station modules provide effective software-based video
compensation features.
• The MC5 stores a video compensation setting for each computer which
defines the level of compensation that is applied whenever the computer
is selected. This “computer video compensation” setting is to correct for
any video clarity loss due to the CATx cable between the MC5 unit and the
computer’s CAM.
Two main types of video compensation are provided within the MC5 installation,
these are:
• Computer video compensation - operates on video signals between each
• CATx cables below 10m give very little loss and so it is not normally
necessary to be concerned about setting any computer video compensation
if short CATx cables are being used between the MC5 and the CAM for
each computer.
• Remote user video compensation - operates on video signals between
each remote user(s) and the MC5 unit. See Remote user video
compensation for details.
• “Computer video compensation” may be setup by typing in the cable
distance in the OSD or, if very fine video adjustment is desired, by observing
the video picture on the local (user 1) port whilst making adjustments.

Computer video compensation
The video compensation for connected computers is achieved using the main
menu. Although the compensation can be applied from any local, remote
or global user port, it is best achieved using the local user port because this
provides the most direct view of the computer output. The compensation
is achieved simply by registering the link cable length, however, different
cables can vary in their characteristics so it is often useful to ‘fine tune’ the
compensation by eye.
Note: CATx cables below 10m give very little loss and so it is not normally
necessary to be concerned about setting any computer video compensation
if short CATx cables are being used between the MC5 and the CAM for each
computer.

Remote user video compensation
To apply remote user video compensation
1 Ensure that the video image from the computer to be used has been
Video compensation for each remote user is provided by their User Station
modules, not by the MC5 unit itself. Using the User Station controls you can
adjust the picture sharpness and brightness to improve the remote picture
quality.

) along with
to
Note: Accurate remote user compensation relies upon visual feedback from the
screen image. It is therefore vital to ensure that the video images being sent out
from the MC5 are as ‘true’ as possible. Ensure, using the local user port, that the
video images received from the computers are correctly compensated BEFORE
attempting to adjust the remote user(s).
The three keyboard indicators (‘Num Lock’, ‘Caps
Lock’ and ‘Scroll Lock’) will now begin to flash in
sequence. The speed of the sequence indicates the
level of the sharpness adjustment currently applied:
the slower the rate, the lower the level of sharpness
being applied.
Video compensation is best carried out when viewing high contrast images with
vertical edges, such as black lines on a white background. When doing so, if you
notice that the screen image is ‘fuzzy’ or ‘dark’ then the image controls may not
be able to solve this condition.
3 While viewing the displayed screen image, use the following keys to adjust
the controls:
Note: If the high contrast images exhibit shadows with separate colours, then
there may be a skew problem which requires a different image adjustment
(provided only by User Station C5 Pro modules) - see the Remote user skew
adjustment section for details.

for coarse adjustment.
To display a suitable high contrast image
The best way to clearly view the effect of sharpness and brightness adjustments
is to display a high contrast image, with vertical
edges, on the screen.
Note: If the monitor goes blank and switches off (due to oversetting
the sharpness adjustment) press the Home key to restore.

Remote user skew adjustment

wires per cable. Three of these pairs are used to convey red, green and blue video
signals to the remote video monitor. Due to the slight difference in twist rate

affects the horizontal placement of the colours and using this pattern it is
much easier to discover which, if any, colours are being adversely affected by
the cable link.
C5 Pro module provides internal skew
adjustment that can help to rectify the
situation. The skew adjustment works
by delaying or advancing the timing
of any of the red, green or blue colour
signals so that they are all delivered to
the monitor at precisely the same time.
For best results, the “skew” program supplied on the disk is the most accurate
way of setting skew as the red, green and blue lines are rendered exactly on the
screen as single pixel wide lines. The skew.bmp test pattern can also be used but
it is less accurate. Alternatively, you can create your own skew pattern using a

Saving and restoring configuration settings
To edit the configuration settings
The MC5 can store up to 512 computer names and 16 sets of user access rights
(MC5-IP models support a maximum of 128 computers). Particularly in cascaded
configurations, manually re-entering all computer names, port numbers and
access rights can be a lengthy process. Therefore, the MC5 provides a method to
save and, if required, restore configuration settings using one of its serial ports.
Further to this, the saved file can be opened and edited within a spreadsheet
and then restored back to the MC5 – a useful way to make multiple setup
changes.
The saved XPRODATA.CSV file can be opened using a spreadsheet program such
as Microsoft Excel. The format of a typical file is shown below. You will see that
the computer names (rows) are tabulated against the user profiles (columns):

What to do if the ADMIN password has been forgotten
If the ADMIN password becomes mislaid or forgotten, you will not be able to
access the MC5 to add or edit users and computer names. This situation may
be resolved by performing a complete reset to return the MC5 or MC5-IP to its
factory default state.
IMPORTANT: A complete reset erases all the user names and computer
names that you have setup.
Slightly different procedures are used to reset the MC5 and the MC5-IP, as
detailed here.

Hot plugging and mouse restoration
To restore mouse operation when hot plugging:
It is strongly recommended that you switch off a computer before attempting
to connect it to the MC5. However, if this is not possible then you need to
‘hot plug’ the computer while it is still running. There is not normally a danger
of damage to the computer, however, when mouse communications are
interrupted, often they fail to re-initialise when reconnected. The MC5 provides
a feature to reinstate mouse communications once the necessary connections
have been made.
1 Using a suitable CAM (Computer Access Module) and category 5, 5e or 6
link cabling, carefully make the connections between the keyboard, monitor,
mouse (and audio) sockets of the computer and the required MC5 port.
3 Highlight ‘Functions’ and press
.
There are two main types of data formats used by current PC mice, these are
the older ‘PS/2’ or ‘standard mouse’ format and the more recent ‘IntelliMouse®’
format introduced by Microsoft. These use slightly different data arrangements
and it is important to know which type was being used before you hot-plugged
the computer to the MC5. The previous setting depends both on the type of
mouse and the type of driver, as various combinations of PS/2 and IntelliMouse
are possible. Using the incorrect restore function may produce unpredictable
results and require the computer to be re-booted.
4 As appropriate, highlight one of the following options:
• Restore Standard Mouse – if PS/2 mode is required, or
• Restore IntelliMouse – if IntelliMouse mode is required.
Then press
.
5 Move the mouse a short distance and check for appropriate on-screen
cursor movement. If the mouse cursor darts erratically around the screen,
then cease moving the mouse. This is an indication that the chosen restore
function is incorrect. Try again using the other restore function.
Which restore setting do I use?
Note: The restore functions predict the likely mouse resolution settings but
may not restore the exact speed or sensitivity settings that were originally
set.
The general rule is that unless both the mouse and the driver are both
IntelliMouse compatible then you need to restore the mouse as ‘PS/2’. An
IntelliMouse can operate in either mode, whereas a PS/2 mouse cannot.
Recognising an IntelliMouse-style mouse
The IntelliMouse format was introduced to support, among other features, the
scroll wheel function. If the mouse has a scroll wheel, then it is likely to support
the IntelliMouse format. If it is a Microsoft-branded mouse, then it will usually
state that it is an IntelliMouse on its underside label.
Recognising an IntelliMouse driver
Before hot plugging to the MC5 (or afterwards using only keyboard control),
access the Windows Control Panel of the computer and select either the Mouse
option (on Windows NT, 2000 and XP) or the System option (on Windows 95,
98, ME). Look for the name of the driver, which will usually include the words
PS/2 or IntelliMouse.

Encryption settings
The MC5-IP offers a great deal of flexibility in its configuration and this extends
equally to its encryption settings that are used to prevent unauthorised
interception of signals. Due to the variety of situations in which the MC5-IP
might be used and the range of viewer applications that need to view it, a
number of settings are available. The encryption settings to use depend upon
how the potential global users will operate.
Important factors to consider when setting these options might be:
• Do all global user connections and operations require encryption?
• Will some global users be using older VNC viewer versions?
MC5-IP encryption settings
The MC5-IP configuration menu offers three encryption settings:
• Always on - This setting will force all viewers to use encryption. Note:
This setting will preclude any VNC viewer versions that do not support
encryption.
• Prefer off - This setting does not enforce encryption unless a viewer
specifically requests it. If a viewer has its ‘Let server choose’ setting, then an
un-encrypted link will be set up.
• Prefer on - This setting generally enforces encryption unless an earlier
viewer version is unable to support it, in which case the link will be un-
encrypted. If a viewer has its ‘Let server choose’ setting, then the link will be
encrypted.
Viewer encryption settings
The web browser viewers and VNC viewers (of level 4.0b5S or higher) offer four
encryption settings:
• Always on - This setting will ensure that the link is encrypted, regardless of
the MC5-IP encryption setting.
• Let server choose - This setting will follow the configuration of the MC5-
IP. If the MC5-IP has ‘Always on’ or ‘Prefer on’ set, then the link will be
encrypted. If the ‘Prefer off’ setting is selected at the MC5-IP, then the link
will not be encrypted.
• Prefer off - This setting will configure an un-encrypted link if the MC5-IP
will allow it, otherwise it will be encrypted.
• Prefer on - If the MC5-IP allows it, this setting will configure an encrypted
link, otherwise it will be un-encrypted.

Networking issues
Thanks to its robust security the MC5-IP offers you great flexibility in how it
integrates into an existing network structure. The MC5-IP is designed to reside
either on an internal network, behind a firewall/router or alternatively with its
own direct Internet connection.
Positioning the MC5-IP in the network
Every network setup is different and great care needs to be taken when
introducing a powerful device such as the MC5-IP into an existing configuration.
A common cause of potential problems can be in clashes with firewall
configurations. For this reason the MC5-IP is designed to be intelligent, flexible
and secure. With the minimum of effort it can reside either behind the firewall
or alongside with its own separate Internet connection.

Placing the MC5-IP behind a router or firewall
A possible point of contention between the MC5-IP and a firewall can
occasionally arise over the use of IP ports. Every port through the firewall
represents a potential point of attack from outside and so it is advisable to
minimise the number of open ports. The MC5-IP usually uses two separate port
numbers, however, these are easily changeable and can even be combined into
a single port.
If you change the VNC port to anything other than 5900, then each VNC viewer
user will need to specify the port address as well as the IP address. For instance,
if you set the VNC port to ‘11590’ and the IP address is ‘192.168.47.10’ then
VNC viewer users will need to enter:
192.168.47.10::11590
(Note the double colons that separate the IP address and port number).
IMPORTANT: The correct configuration of routers and firewalls requires advanced
networking skills and intimate knowledge of the particular network. LINDY
cannot provide specific advice on how to configure your network devices and
strongly recommend that such tasks are carried out by a qualified professional.
The firewall/router would also need to be informed to transfer all traffic to the
new port number through to the MC5-IP.
Addressing
When the MC5-IP is situated within the local network, you will need to give
it an appropriate local IP address, IP network mask and default gateway. This
is achieved most easily using the DHCP server option which will apply these
details automatically. If a DHCP server is not available on the network, then
these details need to be applied manually in accordance with the network
administrator.
Port settings
• Port 80 for users making contact with a web browser, and
• Port 5900 for those using the VNC viewer.
When these port numbers are used, VNC viewers and web browsers will locate
the MC5-IP correctly using only its network address. The firewall/router must be
informed to transfer any traffic requesting these port numbers through to the
MC5-IP.
The firewall/router must then be informed to route incoming requests to port
5900 or port 80 (if available) through to the local address being used by the
MC5-IP.
When a web server is also on the local network
Port 80 is the standard port used by web (HTTP) servers. If the MC5-IP is situated
within a local network that also includes a web server or any other device
serving port 80 then, if you want to use the web browser interface from outside
the local network environment, the HTTP port number of the MC5-IP may need
to be changed.
Remote user with VNC viewer
accesses IP address: 129.7.1.10
and automatically uses port
5900.
When you change the HTTP port to anything other than 80, then each remote
browser user will need to specify the port address as well as the IP address. For
instance, if you set the HTTP port to ‘8000’ and the IP address is ‘192.168.47.10’
then browser users will need to enter:
Internet
MC5-IP has a local address
and net mask, i.e.
http://192.168.47.10:8000
(Note the single colon that separates the IP address and the port number).
Firewall/router address:
129.7.1.10
IP address: 192.168.0.3
Net mask: 255.255.255.0
The firewall routes the
request from the VNC viewer
on port 5900 through to
the MC5-IP at local address
192.168.0.3
The firewall/router would also need to be informed to transfer all traffic to the
new port number through to the MC5-IP.

To discover a DHCP-allocated IP address
Once a DHCP server has allocated an IP address, you will need to know it in
order to access the MC5-IP via a network connection. To discover the allocated
IP address:
select ‘Save’. Once the page is saved, the MC5-IP will contact the DHCP
server and obtain a new address.
2 Re-enter the same ‘Network configuration’ screen where the new IP address
and network mask should be displayed.
DNS addressing
As with any other network device, you can arrange for your MC5-IP to be
accessible using a name, rather than an IP address. This can be achieved in two
main ways:
• For small networks that do not have a DNS (Domain Name System) server,
edit the ‘hosts’ files on the appropriate remote systems. Using the hosts file,
you can manually link the MC5-IP address to the required name.
• For larger networks, declare the IP address and required name to the DNS
server of your local network.
The actual steps required to achieve either of these options are beyond the
scope of this document.

Placing the MC5-IP alongside the firewall
Security can be further improved by using the following suggestions:
MC5-IP is built from the ground-up to be secure. It employs a sophisticated
128bit public/private key system that has been rigorously analysed and found
to be highly secure (a security white paper is available upon request). Therefore,
you can position the MC5-IP alongside the firewall and control hosts that are
also IP connected within the local network.
• Place the MC5-IP behind a firewall and use the port numbers to route the
VNC network traffic to an internal IP address.
• Review the activity log from time to time to check for unauthorised use.
• Lock your server consoles after they have been used.
IMPORTANT: If you make the MC5-IP accessible from the public Internet or from
a modem, care should be taken to ensure that the maximum security available
is activated. You are strongly advised to enable encryption and use a strong
password. Security may be further improved by restricting client IP addresses,
using a non-standard port number for access or limiting remote access to dial up
connections only.
A security white paper that gives further details is available upon request.
Ports
In this configuration there should be no constraints on the port numbers
because the MC5-IP will probably be the only device at that IP address.
Therefore, maintain the HTTP port as 80 and the VNC port as 5900.
Addressing
Ensuring sufficient security
When the MC5-IP is situated alongside the firewall, it will require a public static
IP address (i.e. one provided by your Internet service provider).
The security capabilities offered by the MC5-IP are only truly effective when they
are correctly used. An open or weak password or unencrypted link can cause
security loopholes and opportunities for potential intruders. For network links
in general and direct Internet connections in particular, you should carefully
consider and implement the following:
More addressing information:
• Ensure that encryption is enabled.
• Ensure that you have selected secure passwords with at least 8 characters
and a mixture of upper and lower case and numeric characters.
• Reserve the admin password for administration use only and use a non-
admin user profile for day-to-day access.
• Use the latest Secure VNC viewer (this has more in-built security than is
• Restrict the range of IP addresses that are allowed to access the MC5-IP to
• Add a further level of inherent security by restricting access only via modem
or ISDN dialup.
• Ensure that the computer accessing the MC5-IP is clean of viruses and
spyware and has up-to-date firewall and anti-virus software loaded that is
appropriately configured.
• Avoid accessing the MC5-IP from public computers.

Power switching configuration
Power control sequences
Power switch configuration comprises two main steps:
Note: The settings given below are for the EPS-S8 power switch - other power
switches may require different settings. Please refer to your power switch
documentation for details about codes required by other power switches.
• Configure the POWER CONTROL serial port to the same speed as used by the
page.
The structure of each power sequence (OFF and ON) is as follows:
• Configure power ON and OFF strings for each relevant host computer.
Pxy=z\0D
For each power port there needs to be a valid ‘Power ON string’ and similarly an
appropriate ‘Power OFF string’. In each case, the strings are a short sequence of
characters that combine a port address and a power on or off value.
Where:
x is the switch box number,
y is the power port number,
z is ‘0’ for OFF or ‘1’ for ON, and
\0D represents Enter (or Carriage return).
If a particular computer has more than one power input (and thus requires an
equivalent number of power ports to control them), collections of strings can be
combined to switch all of the required ports together as a group.
To configure the power sequences for each host computer
1 Using VNC viewer or a browser, log on as the ‘admin’ user.
Example 1
To switch ON port 5 of switch box 2, the code would be as follows:
2 Click the ‘Configure’ button in the top right corner.
3 Click the ‘Host configuration’ option.
• Power sequence:
P25=1\0D
Example 2
4 Click a host entry to display a Host configuration dialog:
To switch OFF port 8 of switch box 3, the code would be as follows:
• Power sequence: P38=0\0D
For details about operating this feature, see Power switching (via
Operation chapter.
To control two or more ports simultaneously
You can control up to four power ports using a single sequence. This is done
using the same command structure as shown above, plus a delay command,
for each port. Immediately following a port command, insert the characters
‘\*’ before the next port command, and so on up to four ports. For instance, to
switch on ports 1 and 2 in the first power switch, the command line would be:
6 Enter the Power control sequences in the Power On and Power Off fields
ð
7 Click OK to close the dialog and then click the Save button in the main Host
Configuration window to store the details.

The KVMADMIN utility
Particularly useful for complex MC5 configurations and the control of remote
installations, KVMADMIN is a powerful administration tool.
KVMADMIN is based upon the successful VNC viewer and uses the same
security system. Rather than a graphical interface usch as the standard viewer,
KVMADMIN uses command line control to provide the following administration
facilities:
• Discover and adjust the MC5 configuration, including host systems,
• Save and restore the MC5 configuration,
• Set user names and passwords,
• Download the event log,
• Set custom video modes.
The use of KVMADMIN is strictly limited to the ‘admin’ user and for security
purposes it is not possible to retrieve user names or passwords from the MC5.
To use KVMADMIN you require the IP address and admin password of the MC5
unit. The command line is as follows:
kvmadmin <command> <ip address> [<parameters>]
where <command> is one of the following:
• -setconfig <config-file>
• -getconfig <config-file>
• -setusers <csv-file>
• -getlog <log-file>
• -gethosts <csv-file>
• -sethosts <csv-file>
• -setmodes <csv-file>
For instance, the command line:
kvmadmin -getconfig kvm1.cfg 192.168.2.1
... downloads the current configuration from the MC5 unit at the given address
and stores it in the local file kvm1.cfg.
Whereas the command line:
kvmadmin -setusers users.csv 192.168.2.1
... configures the usernames and passwords for the same unit from the local file
users.csv.
For more information about KVMADMIN, please refer to the user notes supplied
with the utility.

Performing upgrades
4 - Power on the MC5
The MC5 and MC5-IP units are fully reconfigurable via flash upgrades, as are the
individual Computer Access Modules that are used to link all host computers.
The MC5-IP models operate in a slightly different manner to the non-IP models
and so are upgraded differently:
Attach the power adapter to the MC5. The USER display should now show
which indicates that the MC5 is ready to be upgraded.

• A Windows-based upgrade computer with an RS232 serial port.
• The latest version of the KVM Firmware Uploader and firmware files for the
MC5 - contact LINDY support for details.
To use the KVM Firmware Uploader utility
1 - Obtain and run the KVM Firmware Uploader.
Obtain the latest MC5 KVM Firmware Uploader from LINDY support and
install it on a Windows-based upgrade computer that will be connected to
the MC5 unt. The files are supplied as a compressed ZIP file. Decompress the
ZIP file with an appropriate tool such as WinZip (www.winzip.com) and copy
all contained files to the same folder on the upgrade computer.
6 - Query the MC5 unit
Click the Query Unit button to confirm that communication is possible
with the MC5 and to establish the firmware details of the main unit and all
connected CAMs.
2 - Power off the MC5 and select flash upgrade mode
Remove the power supply plug(s) from the rear panel of the MC5 and move
option switch 1 on the back of the MC5 to the ON position (down).
Note: The computer to which each CAM is connected must be powered
before the respective CAM can be accessed.
Note: MC5 units in lower levels of cascade links (and their respective
CAMs) cannot be queried or upgraded while remaining in the cascade
arrangement.
3 - Connect the upgrade computer to the MC5
Connect the upgrade computer to the COM1/UPGRADE port on the rear panel
of the MC5 unit using the optional upgrade cable. You do not need to set
the serial baud rate and protocol because the upgrade program will do this
automatically.
If the application cannot contact the MC5, recheck the connection cable
and click the Advanced... button to check that the correct serial port is being
used. Change the serial port within the Advanced section, if necessary.

Click switch 1 on the rear of the MC5 to the OFF position and disconnect
the power. When the power is re-applied the MC5 will operate using the
new firmware.
When the required options have been selected, click OK.
Note: Approximate upgrade times are: MC5 unit = 4ꢀ minutes; each
selected CAM = 20 seconds.
8 - Select the upgrade file to be used
Issues to consider when performing flash upgrades
From the main KVM Firmware Uploader dialog, click the Browse... button
and select the upgrade file:
The upgrade program rewrites the MC5 firmware code. If the upgrade process is
interrupted then the MC5 will have invalid code and will not be able to operate.
It is therefore good practice to ensure that the upgrade process is always fully
completed. A partial or failed upgrade may be rectified by performing another
upgrade. If the upgrade process is interrupted accidentally then you should
immediately repeat the upgrade process without moving switch 1 from the
upgrade (ON) position. Switch 1 forces the MC5 into flash upgrade mode
and prevents the upgraded code from being run. Running faulty or partially
upgraded code may have unpredictable results and may damage your MC5 or
computing equipment.
MC5 24 port:
MC5_Vxxx
where Vxxx is the upgrade file version number.
The upgrade file details will be displayed within the dialog.
IMPORTANT: Check that the ‘Intended Target Units’ field matches the
‘Unit Connected’ field. If these fields do not match then you may have an
incorrect upgrade file, check with LINDY before proceeding. Check also that
the ‘New firmware version’ is greater than the ‘Current firmware version’.
WARNING: Running faulty or partially upgraded code may have unpredictable
results and may damage your MC5 or computing equipment.

As many computer screen layouts can appear very similar, the MC5 provides a
reminder banner option that indicates which computer port you are currently
viewing. The banner is usually displayed at the top of the screen, using blue
lettering and transparent background. You can:
On occasions it may be useful to know which computers are being accessed,
in which modes and by whom. The most common reason for this would be if
you were denied access to a computer port and needed to find out if another
user has selected ‘Exclusive’ access. For this purpose the MC5 provides the very
handy Routing status feature which provides an ‘at a glance’ view of all current
user connections.

When using the viewer window
Using the viewer window
The viewer window gives you the ability to view and control the MC5-IP and
its host computer(s). Its operation is almost identical regardless of whether you
used the VNC viewer or your Web browser to display it.
What is the best screen resolution to use?
The best resolution for your computer is one that is larger than the screen of the host
computer that you are viewing. This will allow you to see everything without scrolling
around. Alternatively, the VNC viewer can be set to scale the image to fit your screen,
but remember that some pixel dithering effect will be seen when scaling is used.
The menu bar
The viewer window presents a menu bar similar to that shown below. Certain
items within the toolbar are displayed depending upon your access permissions
and/or the MC5-IP configuration.
How do I navigate around a larger screen?
If the screen that you are viewing has a larger resolution than your viewing window
you will need to scroll around to see all items. The viewer window allows you to
‘bump scroll’ (only in full screen mode). This means that when your mouse cursor
bumps against the edge of the screen, the screen image will scroll across automatically.

Both viewers provide a double mouse cursor to help overcome any delays
caused by slow connections. When you move your mouse you will see two
mouse cursors, a local one that responds immediately to your movements and a
second, slower moving, cursor that represents the current mouse position at the
host.
The Hosts button on the menu bar provides the quickest and most efficient way
to switch between host computers. This is because the button is close at hand,
but also because the screen calibration details for each host are reused when
this method of switching is used. The alternative is to use hotkey combinations

Auto calibrate
Re-synchronise mouse
When you visit a host computer for the very first time, your viewer needs to
determine the optimum video and mouse settings for that particular computer.
The button will remind you to click it by flashing red when a new computer
screen is encountered. Performing this step is important because it can help
to decrease unnecessary video information being sent across the link, thus
improving overall performance.
If you find that your local mouse pointer and that of the host are not correctly
synchronised, use this feature to re-align their movements. This operation is also
selectable from the Controls menu.
To re-synchronise the mouse
1 Use the Hosts button to select the required computer.
2 Click the
button and then click OK in the subsequent pop-up message.
Once this has been done, providing you use the ‘Hosts’ button to switch
between host computers, the video settings for each machine will be re-used.
Note: If you find that this doesn’t work, you may need to perform a mouse
calibration again.
Note: When performing an auto calibration, ensure that the screen image
is static (no moving images) and also try to remove any on-screen displays
generated by KVM switches (such as host names or menus). This is because
they can affect the calibration process and result in a lower overall performance
level. For mouse calibration, ensure that there are no application windows
located around the upper left corner of the screen. This is because as the mouse
calibration takes place, the cursor may change (to match the application as it
skims across the window) and this may confuse the calculation. Also ensure that
the host computer does not have the mouse cursor trails option enabled.
Access mode - shared/private
Up to five users can be simultaneously logged-on (four global users plus one
local or remote user) and during normal operation, all are able to see the same
view of the currently selected host. If you need to perform a sensitive task
that should not be viewed by other users, you can change the access mode to
Private. This action blanks the viewer window for all other logged on users.
Note: For the courtesy of other users, this mode should be used sparingly. The
admin user has the ability to overrule the private setting.
To auto calibrate the screen and/or mouse
1 Use the Hosts button to select the required computer.

Video Settings
This dialog provides access to all of the key video settings that determine image
quality and link performance.
Using automatic configurations
• Every setting can be individually subjected to an automatic configuration
(click the appropriate ‘Auto’ button) or can also be manually adjusted.
• Use the ‘Calibrate All’ button to automatically determine the optimum
settings for all items.
Threshold
The threshold is effectively a
noise filter that differentiates
between valid video signals
and background noise or
interference. This has the effect
of reducing unnecessary video
signals between the MC5
and the remote system, thus
improving performance.
Note: Before using the ‘Calibrate All’ option, if possible, remove on-screen
display (OSD) elements generated by the MC5-IP or any other connected
KVM switches (such as a host name label or menu). These OSD elements use
different video rates to those of the host system(s) and can affect the setting
of the automatic threshold value. MC5-IP uses an improved calculation
procedure to filter out the effect of these elements. However, best results
are obtained when the screen contains only host system information.
Note: To maximise performance, the threshold level is automatically
increased by 50% when a slow link is detected.
Phase
The phase setting adjusts the
alignment of the host video
output and the remote system
video display to achieve the
sharpest image.
Note: When the MC5-IP is used with one or more other switches, the
threshold needs to be higher than 32 due to the significant amounts of
‘noise’ that these switches introduce. The MC5-IP configuration should
detect such noise and adjust the threshold accordingly.
Horizontal Position
Determines the horizontal
position of the host screen
image within the viewer
window.

Occasionally it can be useful to manually adjust the Threshold setting, in order to
achieve a setting that best suits your particular requirements.

Access via dial up (modem or ISDN) link
If you need to enter a port number
When you gain access via modem or ISDN link, the MC5-IP uses standard
network protocols to create a private two-device network. This approach
ensures consistency and allows you to use exactly the same VNC viewer or
browser to view the host computers. This is achieved using PPP (Point to Point
Protocol) and means that you need to use a dial-up networking method to
initiate the connection. Such software is standard with operating systems such
as Windows, Linux and Mac OS.
Usually, when you make a network connection to the MC5-IP (either using the
VNC viewer or a Web browser) you simply enter the IP address, i.e. 192.168.0.3.
However, if a special configuration is necessary, then you may be asked to
specify a port number as well as the IP address.
To enter a port number in a Web browser
1 Enter the required IP address in the usual Address box,
i.e. http://192.168.0.3
To initiate a dial up link
1 Using a system that has a modem or ISDN adapter installed, locate the
dial-up networking option on your system. Please refer to your system
documentation for more information.
2 At the end of the IP address, add a single colon (:) and then enter the port
number (in this example, the required port number is 8000),
i.e. http://192.168.0.3:8000
2 Using the dial-up networking option, enter the telephone/ISDN number
where the MC5-IP can be contacted.
To enter a port number in VNC viewer
1 Enter the required IP address in the usual ‘Server’ box,
i.e. http://192.168.0.3
3 Initiate the call and when the link is made, continue with either the standard
Note: For the viewer network connection address, you must use the IP
address that the admin user has set as the Server address (or PPP server IP
address) within the Modem configuration screen.

The MC5 supports an autoscan mode that automatically scans between the
connected computers in sequence. There are three autoscan modes. In the
first mode the MC5 will scan all the named computers that are defined in
the autoscan list (SCAN LIST). The computers defined in the scan list may be
connected to cascaded MC5 units. If you wish to scan the ports on the current
MC5 then you may select ALL the available computers or just the available
computers that are currently powered on (the ACTIVE computers). Scanning just
the active computers avoids blank screens from being displayed and stops the
monitor from going into a power down state on every scan cycle.

WARNING - Many modern monitors are fitted with automatic power
save relays and will switch off after a few seconds if connected to an
inactive PC. If you are using such a monitor you must not set the MC5 to
scan ALL ports. Constant switching on and off of your monitor’s relay will
eventually damage your monitor. If you are using the SCAN LIST option
then you should ensure that all the computers are active if you are using
one of these monitors.
Esc-Quit
Mouse Switching
Settings: ENABLED, DISABLED
The computer channel can be switched using a three button mouse or
IntelliMouse. Pressing the central button or wheel button together with the
left hand mouse button will cause the MC5 to switch to the next available
computer. When mouse switching is enabled the central mouse button or wheel
mouse button is allocated to control the MC5 and is not therefore available
for use by computer applications. If you want to use the central mouse button
within your applications you will need to disable mouse switching. The rotation
action of an IntelliMouse wheel is not affected and is always available to the
computer application.
If you choose to use the SCAN LIST option then you may define the computers
to be scanned in the following manner.
To define the autoscan list
1 From the main on-screen menu press F1 for MORE MENUS.
2 Select EDIT AUTOSCAN LIST from the menu. A list of defined computers
will appear. Computers affixed with a ‘+’ will be autoscanned during the
autoscan cycle. To add/remove a computer to/from the autoscan list, move
the selection bar over the computer name and press SPACE BAR. To add all
named computers press F1. To remove all named computers press F2.
Screen Saver
Settings: DISABLED; 2, 5, 7, 10,15, 20 & 30 MINUTES
To avoid burning out the phosphor on CRT monitor screens, the MC5 can be set
to blank the screen after no keyboard or mouse activity has been detected for
a selected timeout period. If preferred, the user can blank the screen manually
by selecting channel ‘0’ using the keyboard hotkeys or by pressing ESC from the
login screen.
3 When all the computers that you wish to scan are affixed with a ‘+’, press
RETURN or ENTER to save the selections. The selected computers will be
autoscanned in alphabetical order when you activate autoscan mode (when
the SCAN LIST option is selected).
Autoscan Period
Settings: DISABLED; 2, 5, 7, 15, 30 SECONDS, 1, 5 MINUTES
The autoscan time defines the length of time that the MC5 will display video
(and play audio) from an autoscanned computer before changing to the next
computer. If the DISABLED setting is chosen then no autoscan functions will be
available.

RS232 Mouse Type
OSD Dwell Time
Settings: INTELLIMOUSE, 2 BUTTON, 3 BUTTON
Settings: 1, 2, 3, 5, 10 SECONDS
This setting controls the type of RS232 mouse that the MC5 reports to
computers. All the necessary conversions are dealt with automatically by the
MC5. The IntelliMouse setting sends four byte mouse reports to the computers
and is therefore very slightly more sluggish than the others that send three byte
mouse reports. RS232 mice are almost always more sluggish than PS/2 types
because the data rate is much slower.
After a successful computer channel change the MC5 will display a confirmation
message for a few seconds. The length of time that this confirmation message
dwells on the screen may be changed.
User Timeout
Settings: 1, 2, 5, 10, 30 SECONDS, 1, 5, 10 MINUTES
When two users are connected to the same computer only one can have access
at any one time. When no keyboard or mouse data has been received from the
active user port for the user timeout period, the MC5 will allow other users to
access the computer. The new port then becomes the active port until it too
times out. To avoid confusion between users it is desirable to set the timeout
period to be sufficiently long so that user’s work is not needlessly interrupted by
other users and sufficiently short to ensure good overall system efficiency. The
user timeout value also controls the timeout between the local port and remote
(extended) user port 1.
Mouse Type
Settings: LOGITECH, MICROSOFT
This setting determines how the mouse type is reported to each connected PC.
Some Logitech mouse drivers are unable to handle the more advanced features
of Microsoft Intellimouse Explorer type mice, so the LOGITECH setting here
reports a more basic mouse type.

computer channels selected).
Security
Settings: DISABLED, ENABLED
With security disabled there is no requirement for users to log-in to the system.
All users have full access to all the connected computers and full administration
rights. With security enabled, users are required to log-in to the MC5. Each user
is allocated access rights to computers by the system administrator and they
are only able to see the computers that they have access to on their on-screen
menu.
Exclusive Use
Settings: ALLOWED, DISABLED
In normal operation, the MC5 will allow two or more users to share access to
a computer. In this mode, the computer’s video picture will be displayed on all
the users’ monitors but only one user may have active control of the computer’s
keyboard and mouse at any one time. The MC5 detects an active user by
checking for keyboard and mouse data.
Language
Settings: ENGLISH, FRENCH, GERMAN, SWEDISH
A user becomes inactive if no keyboard or mouse data has been received by
the MC5 for a specified timeout period. Whilst one user is active all the other
users that are connected to the same computer will see a “video only” message
displayed on their screen. There may be situations where particular users wish
to control and view a computer in private with exclusive use. The MC5 has the
facility to allow users to select exclusive use of computers, however, this facility
should be used with care.
This option specifies the language that is used for the on-screen menu and the
keyboard layout that is assumed for the keyboard. When the French option is
selected the keyboard is assumed to have an AZERTY format. When the English,
German and Swedish options are selected the keyboard is assumed to have a
QWERTY format. The new language settings are enabled when you quit from
the SETUP OPTIONS menu. The language option only affects the way that the
MC5 interprets the keyboard keys, it does not affect the way that the computers
interpret the keyboard. It is advisable to avoid setting a language that you do
not understand as all the menus will change to use the new language and you
may have difficulty reselecting your original language.
Users that have selected exclusive access are never timed out by the MC5 and
so all other users are effectively “locked out” until the exclusive user switches to
another computer or logs out. This could potentially be very irritating if a user
has selected exclusive use and has then left their desk without logging out. This
would prevent other users from working on the computer until they came back.
Consequently the system administrator can disable all exclusive use so that all
connections are shared.

Automatic Logout
Settings: DISABLED, ENABLED
The MC5 enables you to restrict access to your computers on a login basis. If
a user forgets to logout when they have finished accessing the MC5 then the
user console may unintentionally be left with full access to all the computers.
The MC5 can be set to automatically logout unattended user consoles when the
screen saver kicks in. This reduces the risk of security problems by preventing
user consoles remaining in a permanent “logged-in” state when there is no
keyboard or mouse activity. The automatic logout feature is only enabled when
the screen saver feature is active (i.e. not disabled).

DDC Options
The options within this section are concerned with the operation of the POWER
CONTROL port when used to command optional system power control units.
The options within this section are related to the Display Data Channel features

of 9600.
Determines which user port monitor should be interrogated to discover its
capabilities. AUTO begins with the local user port and if it fails, it uses a set of
default values. The LOCAL setting forces the unit to interrogate only the local
monitor and DEFAULT uses only the pre-programmed settings.
Format
Settings: NONE.8.1, ODD.8.1, EVEN.8.1, NONE.8.2, NONE.7.2, ODD.7.2,
EVEN.7.2
DDC Refresh
Settings: AT START, DISABLED
Configures the data format used by the serial port and must match the format
used by the connected power switche(s). The NONE/ODD/EVEN portion relates
to the parity checking; the 7/8 value is the size of the data byte and the 1/2
value determines the stop bit(s) used after each data byte.
AT START sets the MC5 to read DDC information from the selected source
at power up. When DISABLED, no new DDC data is sought and existing
information is used. When viewing this menu, press F8 to discover DDC
information from the chosen source immediately.

Also often called the ‘subnet-mask’, this value is used alongside the IP address
to help define a smaller collection (or subnet) of devices on a network. In this
way a distinction is made between locally connected devices and ones that are
reachable elsewhere, such as on the wider Internet. This process helps to reduce
overall traffic on the network and hence speed up connections in general.

circumstances it may be advantageous to alter this number - see Security issues
with ports for more details.
Use DHCP
DHCP is an acronym for ‘Dynamic Host Configuration Protocol’. Its function is
particularly useful when connecting to medium size or larger networks, such
as the Internet. When this option is selected, your MC5-IP will attempt to
locate a DHCP server on the network. If such a server is located, it will supply
three things to the MC5-IP: an IP address, an IP network mask (also known
as a Subnet mask) and a Gateway address. These are not usually granted
permanently, but on a ‘lease’ basis for a fixed amount of time or for as long as
Note: The VNC port and HTTP port can be set to the same port number in order
to simplify router and firewall configuration. If this is done then the MC5-IP will
“listen” for both types of traffic on the single port.
HTTP Port
This is the logical link through which communications with a remote web
browser will be channelled. The default setting of 80 is an established standard
for web (HTTP – HyperText Transfer Protocol) traffic though this can be changed
to suit your local network requirements.
IP Address
This is the identity of the MC5-IP within a network. The IP address can be
thought of as the telephone number of the MC5-IP. Unlike the MAC address,
the IP address can be altered to suit the network to which it is connected. It can
either be entered manually or configured automatically using the DHCP option.
When the DHCP option is enabled, this entry is unavailable.
Clear IP Access Control
This option removes all entries from the IP access control feature within the
MC5-IP. The IP access control feature (configurable by a global admin user)
allows certain network address ranges to be denied access to the MC5-IP. If set
incorrectly, it is possible to exclude all network users and so this option provides
an emergency recovery point.

Mouse Latency Allowance
This option is used during calibration to account for latency delays (caused
as signals pass through a device) introduced by some KVM switches from
alternative manufacturers.
During calibration, the MC5 waits for 40ms after each mouse movement before
sampling the next. If a KVM device adds a significant delay to the flow of data, the
calibration process can be lengthened or may fail entirely. The value entered here is
added to (or subtracted from) the default 40ms sampling time.
Note: You can enter negative values (down to -40) in order to speed up the
calibration process when using fast KVM switches. Use this option with caution
as it can adversely affect the calibration process.
Mouse Rate
Defines the rate at which mouse movement data are transmitted to the system. The
default option is 20ms, which equates to 50 mouse events per second. This default
rate can prove too fast when passed through certain connected KVM switches from
alternative manufacturers. In such cases, data are discarded causing the local and
remote mouse pointers to drift apart. If this effect is encountered, increase the mouse
rate to around 30ms (data are then sent at a slower rate of 33 times per second).
Background Refresh Rate
Use the arrow keys to alter the refresh rate for screen images via remote links. This
allows you to tailor the screen refresh to suit the network or modem connection
speeds. The options are: Slow, Medium, Fast or Disabled. When the disabled
option is selected, the remote users will need to manually refresh the screen.
To get here
Note: When a low connection speed is detected, the background refresh is
automatically disabled, regardless of the settings of this option.

Force VNC Protocol 3.3
Behaviour for admin connections when limit reached
IMPORTANT: The use of this option is not recommended. Protocol 3.3 is a legacy
version that does not offer any encryption.
Determines what should occur when four global connections already exist and
a fifth, administrator connection attempt is made. Options are: Replace oldest
connection, Replace newest connection and Don’t replace. Only non-administrator
connections can be terminated in this way.
Idle Timeout
Determines the period of inactivity on a global connection before the user is logged
out. The idle timeout period can be set to any time span, expressed in minutes.
Use VESA GTF
When ticked, the VESA Generalized Timing Formula will be used to help
determine the correct input video resolution and timing details. See Appendix 9
for a list of all supported video modes.
Protocol Timeout
Sets the time period by which responses should have been received to outgoing
data packets. If the stated period is exceeded, then a connection is considered
lost and terminated.

Time & date configuration
This page allows you to configure all aspects relating to time and date within the
MC5-IP unit.
Timezone specifier
Optionally enter a recognised timezone specifier related to the current position
of the MC5-IP unit. When an NTP server is used, the specifier will be used to
provide the correct real time.
The timezone specifier takes the following form:
std offset dst [offset],start[/time],end[/time]
The std and offset specify the standard time zone, such as GMT and 0, or
CET and -1, or EST and 5, respectively.
The dst string and [offset] specify the name and offset for the
corresponding Daylight Saving Time zone; if the offset is omitted, it defaults
to one hour ahead of standard time.
The remainder of the specification describes when Daylight Saving Time is
in effect. The start field is when Daylight Saving Time goes into effect and
the end field is when the change is made back to standard time. The most
common format used for the daylight saving time is: Mm.w.d
Where: m specifies the month and must be between 1 and 12. The day d
must be between 0 (Sunday) and 6. The week w must be between 1 and
5; week 1 is the first week in which day d occurs, and week 5 specifies the
last d day in the month.
The time fields specify when, in the local time currently in effect, the change
to the other time occurs. If omitted, the default is 02:00:00.
Typical examples are:
UK:
GMT0BST,M3.5.0/1,M10.5.0/2
CET-1CEST,M3.5.0/2,M10.5.0/3
EST5EDT,M4.1.0/2,M10.5.0/2

Network configuration
To get here
1 Using VNC viewer or a browser, log on as the ‘admin’ user.
This page allows you to configure the various aspects of the IP port and its
relationship with the local network.
2 Click the ‘Configure’ button in the top right corner.
3 Click the ‘Network configuration’ option.
IP Address
thought of as the telephone number of the MC5-IP. Unlike the MAC address,
the IP address can be altered to suit the network to which it is connected. It can
either be entered manually or configured automatically using the DHCP option.
When the DHCP option is enabled, this entry is greyed out.
IP Network Mask
to help define a smaller collection (or subnet) of devices on a network. In this
way a distinction is made between locally connected devices and ones that are
reachable elsewhere, such as on the wider Internet. This process helps to reduce
overall traffic on the network and hence speed up connections in general.
IP Gateway
This is the address of the device that links the local network (to which the
MC5-IP is connected) to another network such as the wider Internet. Usually
the actual gateway is a network switch or router and it will be used whenever a
required address lies outside the current network.
VNC Port
MAC address
This is the logical link through which communications with a remote VNC viewer
a widely recognised port number for use by VNC software. However, in certain
circumstances it may be advantageous to alter this number - see ‘Security issues
with ports’ for more details.
Media Access Control address – this is the unique and unchangeable code that
was hard coded within your MC5-IP unit when it was built. It consists of six 2-
digit hexadecimal (base 16) numbers separated by colons. A section of the MAC
address identifies the manufacturer, while the remainder is effectively the unique
electronic serial number of your particular unit.
HTTP Port
Use DHCP
This is the logical link through which communications with a remote web
established standard for web (HTTP – HyperText Transfer Protocol) traffic though
this can be changed to suit your local network requirements.
DHCP is an acronym for ‘Dynamic Host Configuration Protocol’. Its function is
particularly useful when connecting to medium size or larger networks, such
as the Internet. When this option is selected, your MC5-IP will attempt to
locate a DHCP server on the network. If such a server is located, it will supply
three things to the MC5-IP: an IP address, an IP network mask (also known
as a Subnet mask) and a Gateway address. These are not usually granted
permanently, but on a ‘lease’ basis for a fixed amount of time or for as long as
IP Access Control
This section allows you to optionally specify ranges of addresses which will or
won’t be granted access to the MC5-IP. If this option is left unchanged, then the
default entry of ‘+0.0.0.0/0.0.0.0’ ensures that access from all IP addresses will

Setting IP access control
The golden rule with this feature is ‘Include before you exclude’ or to put it
another way ‘Arrange allowed addresses in the list before the denied addresses’.
To define a new IP access control entry
1 Click the Add button to display a popup dialog:
This is because the positions of entries in the list are vitally important. Once a
range of addresses is denied access, it is not possible to make exceptions for
particular addresses within that range. For instance, if the range of addresses
from A to F are denied access first, then the address C could not be granted
access lower down the list. Address C needs to be placed in the list before the
denied range.
IMPORTANT: This feature should be configured with extreme caution as it is
possible to deny access to everyone. If such an error occurs, see Clearing IP
access control for details about how to regain access.
Network/Address

Enter the network address
that is to be allowed or denied

Mask entry to indicate the size
of the range.
Enter an IP network mask
that indicates the range of
addresses that are to be

Serial port configuration
This page provides all access to settings concerned with the two serial ports
(modem and power control) that are situated at the rear of the MC5-IP unit.
Modem port
PPP Server IP Address / PPP Client IP Address
When a user dials into the MC5-IP via a modem or ISDN adapter, the MC5-IP
sets up a temporary two-device network using PPP (Point to Point Protocol). For
this purpose, both devices must have ‘dummy’ IP addresses so that they can
communicate correctly. These two addresses can be almost anything expressed
in the quad octet format (i.e. 192.168.3.1.). However, it is advisable not to make
them the same as the real IP addresses used by either the remote system or the
MC5-IP.
Baud Rate
This option configures the speed of the serial connection between the MC5-
IP and a connected modem or ISDN terminal adapter. The default setting is
115200. The other communication settings are fixed as: No parity, 8 bit word, 1
stop bit.
Initialization Sequence
The codes entered here are used to prepare the connected modem or ISDN
terminal adapter for use with the MC5-IP. The default code is a Hayes-
compatible string to configure auto answer mode and would be understood by
the vast majority of modem/ISDN devices. The code is sent when the MC5-IP is
first switched on or whenever the Initialize button is clicked.
Initialise
When clicked, this option sends the characters entered in the Initialization
sequence field to the connected modem or ISDN terminal adapter.

Restore Defaults
1 Using VNC viewer or a browser, log on as the ‘admin’ user.
When clicked, this option resets the Baud rate and Initialization sequence values
to their original default settings.
2 Click the ‘Configure’ button in the top right corner.
3 Click the ‘Serial port configuration’ option.
Power control port
Baud Rate
This option configures the speed of the serial connection between the MC5-
IP and a connected power control unit. The default setting is 9600 as used by
the majority of power units. The other communication settings are fixed as: No
parity, 8 bit word, 1 stop bit.

Host configuration
This page provides the opportunity to configure various details for each of the
host systems that may be connected to the MC5-IP via one or more KVM switch
units. There are 128 entries, each of which can be configured with a name,
the permitted users, the hot key combinations required to switch to it and, if
required, appropriate power control commands.

Port Direct
Port Direct is totally transparent communication system that allows supporting
devices to communicate with each other. Using the keyboard connections that
link each device, Port Direct allows:
• A controlling device to provide address details of the required port, the user’s
name and access rights, mouse calibration and video mode information.
• A controlled device to confirm the address and other details of the current
port.
Such communication simplifies both the configuration and selection of systems,
especially within a complex cascade structure. Port Direct also allows the MC5
Hosts option to directly control the connected switching devices (such as other
MC5 units in cascade) and then apply the appropriate video capture and
mouse scaling settings. Port Direct provides excellent security control to prevent
users from accessing systems for which they do not access rights (‘sideways
movement’) because each unit is fully informed of each user’s precise access
rights.
Port/host addressing using Port Direct
When adding new computers to the Hosts list, the option ‘Add entry for
unrecognised host’ is provided to automatically add new entries if a port is
visited that does not already have a matching host entry. This is a useful option
for simple configurations, but should be used with care when complex cascades
of units are being used as it may lead to more host entries being added than are
strictly necessary.
Additionally, you can specify the port number of the required system using the
same format as if controlling the KVM switch directly. Port numbers MUST be
entered within square brackets and can be specified to a maximum of four
cascaded levels.
Examples
[16]
selects port 16 and is equivalent to the hotkey sequence +CTRL+ALT+–
1+6
[4105] selects port 5 on MC5 unit that is cascaded through port group 41

Appendix 3 - VNC viewer connection options
When you are connecting to the
MC5-IP using the VNC viewer, a
number of options are available.
Colour/Encoding
Auto select
When ticked, this option will
examine the speed of your
connection to the MC5-IP and
apply the most suitable encoding
method. This option is suggested
for the majority of installations.
Click here to
access the options
There are six tabbed pages of options:
• Colour/Encoding
• Inputs
Preferred encoding
There are three manually selectable
encoding methods which are
accessible when the Auto select
option is unticked.
• Scaling
• Misc
• ZRLE – This is a highly
compressed method that is
best suited to slow modem
connections.
• Hextile – This method offers
better performance than the
ZRLE when used over a high speed network because there is no need for the
MC5-IP to spend time highly compressing the data.
• Raw – This is a primitive, uncompressed method that is mainly used for
technical support issues. You are recommended not to use this method.
Colour level
This section allows you to select the most appropriate colour level for the
speed of the connection to the MC5-IP. Where the connection speed is slow or
inconsistent there will be a necessary compromise between screen response and
colour depth.
• Full – This mode is suitable only for fast network connections and will pass
on the maximum colour depth being used by the host system.
• Medium (256 colours) – This mode reduces the host system output
to a 256 colour mode and is more suitable for ISDN and fast modem
connections.
• Low (64 colours) – This mode is suitable for slower modem connections
and reduces the host system output to 64 colours.
IMPORTANT: If you make any changes to the options given here and wish to
retain them for successive connection sessions, you must save the changes.
To do this, change to the ‘Load/Save’ tab and click the ‘Save’ button within the
‘Default’ section.
• Very low (8 colours) – This mode provides very rudimentary picture
quality and hardly any speed advantage over the 64 colour setting. You are
recommended not to use this mode.

Appendix 6 – Addresses, masks and ports
Net masks
IP address, network masks and ports are all closely linked in the quest for one
device to find another across disparate network links.
The net mask (or sub-net mask) informs a device as to its own position within a
network. From this it can determine whether any other device is within the same
local network or is situated further afield.
IP addresses
Taking the telephone number analogy given in the IP address section, in order
to use the telephone system efficiently, it is vital for you to know your location
relative to the person you are calling. In this way you avoid dialling unnecessary
numbers.
As a rough analogy, consider how you use the telephone system. The phone
number for LINDY in the UK is 0044 (0)1642 754000. This number consists of
three distinct parts:
When one network device needs to talk to another, the first thing that it will
do is a quick calculation using its own IP address, the other device’s IP address
and its own net mask. Suppose a device with address 192.168.142.154 and
net mask 255.255.255.0 needed to communicate with a device at address
192.168.142.22. The sending device would perform several calculations:
• 0044 connects from another country to the UK
• (0)1642 selects the main telephone exchange in the Thornaby area of
Stockton-on-Tees, and
• 754000 is the unique code for LINDY within Thornaby.
The important parts of the whole number depend on where you are. If you were
based in the same local area as LINDY, there would be no point in dialling out of
the UK, or even out of the area. The only part of the whole number that you are
interested in is the final part: 754000.

192 168 142 22
192 168 142 000
In a similar way to the various parts of the telephone number, the four sections
(or Octets) of every IP address have different meanings or “weights”. Consider
the following typical IP address:
Net mask
Result
3
2
192.168.142.154
192 is the most global part of the number (akin to the 0044 of the phone
number) and 154 is the most local (similar to the 754000 unique local code of
the phone number).
192.168.142.000 = 192.168.142.000 ? Answer: YES
4
Address
is local
When two network devices communicate with each other, they always “dial the
whole number” regardless of their respective locations in a network. However,
they still need to know whether the other device is local to them or not, and this
is where the net mask comes into play.
1 The net mask is used to determine the local and global parts of the sender’s IP
address. Where there is 255 in the mask, the corresponding address slips through,
where there is a 0, it is blocked.
2 Where the net mask was 0, the corresponding part of the result is also zero - this
section is now known to be the local part of the IP address.
3 The same process is carried out for the destination address, again using the sender’s
net mask. Now the local parts of both addresses have been equalised to zero, because
their values are not important in determining whether they are both in the same local
network.
4 The results of the two net mask operations are now compared, if they match, the
destination is local. If not, then the sender will still use the same full destination IP
address but will also flag the message to go via the local network gateway and out
into the wider world.
The reason for doing this? It makes the network, as a whole, much more
efficient. If every message for every recipient was shoved straight out onto the
Internet, the whole thing would grind to a halt within seconds. Net masks keep
local traffic just that - local.

Net masks - the binary explanation
To really understand the operation of a net mask it is necessary to delve deeper
into the life blood of computers – binary; this is native digital, where everything
is either a 1 (one) or 0 (zero), on or off, yes or no.
AND function’. The example of 255.255.255.0 is handy because the last octet
is completely zero and is “clean” for illustrative purposes. However, actual net
mask calculations are carried out, not on whole decimal numbers, but bit by bit
on binary numbers, hence the term ‘bit-wise’. In a real local network, a net mask
might be 255.255.255.240. Such an example would no longer be quite so clear,
until you look at the net mask in its binary form:
11111111.11111111.11111111.11110000
In this case, the four zeroes at the end of the net mask indicate that the local
part of the address is formed by only the last four bits. If you use the diagram
from the previous example and insert the new net mask, it will have the
following effect on the final result:
Decimal octet prior to AND
operation with net mask

Inside a bit-wise AND function
When you “open up” the last octet
of the net mask and look at the
binary inside, you can see the last
four zero bits preventing any 1’s in
the address from falling through.
10010000
Binary octet after AND
operation with net mask
Decimal equivalent of 10010000
144
Thus, when 154 is bit-wise ANDed with 240, the result is 144. Likewise, any
local address from 192.168.142.144 through to 192.168.142.159 would
produce exactly the same result when combined with this net mask, hence they
would all be local addresses. However, any difference in the upper three octets
or the upper four bits of the last octet would slip through the mask and the
address would be flagged as not being local.

Calculating the mask for IP access control
The permissible mask values (for all octets) are as follows:
The IP access control function uses a standard IP address and a net mask
notation to specify both single locations and ranges of addresses. In order to
use this function correctly, you need to calculate the mask so that it accurately
encompasses the required address(es).
Mask octet

2 addresses
Single locations
252
4 addresses
Some of the simplest addresses to allow or deny are single locations. In this case
you enter the required IP address into the ‘Network/Address’ field and simply
enter the ‘Mask’ as 255.255.255.255 (255 used throughout the mask means
that every bit of the address will be compared and so there can only be one
unique address to match the one stated in the ‘Network/Address’ field).

The other easy setting to make is ALL addresses, using the mask 0.0.0.0 As
standard, the IP access control section includes the entry: 0.0.0.0/0.0.0.0
0
+
If the access control range that you need to define is not possible using one
address and one mask, then you could break it down into two or more entries.
Each of these entries could then use smaller ranges (of differing sizes) that,
when combined with the other entries, cover the range that you require.
The purpose of this entry is to include all IP addresses. It is possible to similarly
exclude all addresses, however, take great care not to do this as you instantly
Address ranges
For instance, to accurately encompass the range in the earlier example:
Although you can define ranges of addresses, due to the way that the mask
operates, there are certain restrictions on the particular ranges that can be set.
For any given address you can encompass neighbouring addresses in blocks of
either 2, 4, 8, 16, 32, 64, 128, etc. and these must fall on particular boundaries.
For instance, if you wanted to define the local address range:
192.168.142.67 to 192.168.142.93
You would need to define the following six address and mask combinations in
the IP access control section:
Network/address entry Mask entry
192.168.142.67 to 192.168.142.93
192.168.142.67
192.168.142.68
192.168.142.72
192.168.142.80
192.168.142.88
192.168.142.93
255.255.255.255
255.255.255.252
255.255.255.248
255.255.255.248
255.255.255.252
255.255.255.255
defines 1 address (.67)
The closest single block to cover the range would be the 32 addresses from:
192.168.142.64 to 192.168.142.95.
defines 4 addresses (.68 to .71)
defines 8 addresses (.72 to .79)
defines 8 addresses (.80 to .87)
defines 4 addresses (.88 to .92)
defines 1 address (.93)
The mask needed to accomplish this would be: 255.255.255.224
When you look at the mask in binary, the picture becomes a little clearer. The
above mask has the form: 11111111.11111111.11111111.11100000
Ignoring the initial three octets, the final six zeroes of the mask would ensure
that the 32 addresses from .64 (01000000) to .95 (01011111) would all be
details.
When defining a mask, the important rule to remember is:
There must be no ‘ones’ to the right of a ‘zero’.
For instance, (ignoring the first three octets) you could not use a mask that had
11100110 because this would affect intermittent addresses within a range in an
impractical manner. The same rule applies across the octets. For example, if you
have zeroes in the third octet, then all of the fourth octet must be zeroes.

Ports
Security issues with ports
The settings of port numbers become important when the MC5-IP is situated
behind a network firewall. In order for a remote VNC viewer or web browser
to make contact with your MC5-IP, it is necessary for the firewall to allow
communication through a particular numbered port to occur.
then think of ports as extension numbers. In a company of any size, you
generally wouldn’t expect the accounts department to share the same telephone
with the technical department. Although their calls may all be related to the
same company, they concern very different aspects of that company.
One specific function of firewalls is to restrict access to ports in order to prevent
malicious attackers using them as a route into your network. Every new port
that is opened offers a new possibility for hackers and so the number of
accessible ports is purposefully kept to a minimum. In such cases, it may be
advantageous to change one or both MC5-IP ports to use the same number. The
other alternative is to place the MC5-IP unit outside the firewall and take full
It is the same with IP network connections. Although you have only one network
link into your computer and only one IP address (phone number), you are
probably performing many different tasks through that one link, often at the
same time. Thus, when you browse the web your outgoing requests and the
incoming information are all channelled through port 80. When you send an
email, it travels through port 25 and when you transfer files you are, without
knowing it, using port 20.
IMPORTANT: The correct configuration of routers and firewalls requires advanced
networking skills and intimate knowledge of the particular network. LINDY
cannot provide specific advice on how to configure your network devices and
strongly recommend that such tasks are carried out by a qualified professional.
At the “border crossing” between the wider Internet and every local network
attached to it, there is a router that is usually combined with a firewall. One of
its main tasks is to direct incoming traffic to the correct place within its local
network. A key piece of information to help it do this is the port number:
User with VNC viewer accesses
IP address: 129.7.1.10 (this
automatically uses port 5900).
User accesses the company
website at: 129.7.1.10 (this
automatically uses port 80).

Router/firewall address: 129.7.1.10
