■ Operation
One-Console KVM Switches
one
The KVM Switch allows you to access multiple computers from
keyboard, mouse and monitor. There is no interface card or
software to configure. Installation is as easy as connecting cables
between the KVM Switch and your computers. Operation is as
simple as pressing push button, entering hot-key command and
navigating through the user-friendly on-screen menu (available on
models with OSD support). Depending on the model you have, it
switches up to 4 (KNV104), 8 (KNV108) or 16 (KNV116D)
IBM-compatible computers. The KVM Switch is independent of the
computer operating system.

Configurations
Cascade (Master/Slave) Configuration
PC
The KVM Switch has several models each supporting a different
number of computers. For applications with a large number of
computers, KVM Switches can be cascaded in a master/slave
configuration to support even more computers.
You can connect a second level of one or more KVM Switches to “

Single KVM Switch Configuration
Once connected, KVM Switches automatically configure themselves
to either Master or Slave. Slaves of different models can be mixed
in cascade configuration. [NOTE: Master must have equal or more
PC ports than that of Slaves, i.e., if KNV108 is a master, KNV108 and
KNV104 can be Slaves, but KNV116D can not.]

Initial Power-Up
Make sure all computers and KVM Switches are powered down
during installation. You must power up the Master KVM Switch
before turning on any other devices.
ꢀ For single KVM Switch: 1) Apply a power adapter to the
Master. 2) Turn on computers.
ꢀ For cascade: 1) Apply a power adapter to the Master.
2) Apply power adapters to all Slaves.
3) Turn on
computers.
Note: You may hot plug additional powered-down computer and
Slave without turning any existing KVM Switch or computer off after
initial power up.

J To select a computer by hot-key command, you must know its port
address, which is determined by the KVM Switch connection.
For a computer connected to a Master, its address is represented
by the PC port label (1~8 or A~H). For a computer connected to
a Slave, two characters represent its address. The first character
is the port address of the Master unit (1~8) and the second one is
the port address of the Slave (1~8 or A~H). Please note that

Connection
Before connecting a device (a computer or a Slave) to the Master
under power, you must turn off the device. The Master must have
equal or more 'PC x' ports than that of the Slave, i.e., if KNV108 is
the master, KNV108 and KNV104 can be Slaves, but KNV116D can
not.

After connection completes, you should re-activate the
OSD menu to check if the Master recognizes the
Slaves. A triangle mark (ꢀ) is placed to the right of
the port name indicating the port is connected to a
Slave not a computer. A number to the left of the
triangle mark indicates the Slave model, i.e. 8ꢀ for
KNV108 or KNV108D.
Overview
The advanced multi-access KNV2108D and KNV2116D have all the
features of KNV108D and KNV116D respectively. Both models
have two Console ports facilitate you to access multiple computers
from one out of two locations, local and remote. Thanks to the
high-drive circuit design, you may connect high quality cables at
Console and PC sides for up to 100ft (30M), a definite plus for server
room applications. Now you can access all computers either in the
server room when you have to physically access the computers such
as software upgrade, or away from the server room for everyday use.

Refer to the chapter Cascade Configuration for more detail. There
are rules to apply for Master/Slave configuration. When KNV2108D
is a Master, its slave includes KNV104, KNV104D, KNV108 and
KNV108D. When KNV2116D is a Master, its slave includes all the
above and KNV116D. These multi-access KVM Switches already
come with OSD menu, their Slaves do not have to be OSD equipped.
* Cascaded with KVM Switches supporting the same number of PC ports. You can
mix different models in cascade applications.
