NPort 5110 Series User’s Manual
Initial IP Address Configuration
Initializing NPort 5110’s IP Address
1. Determine whether your NPort 5110 needs to use a Static IP or Dynamic IP (either DHCP or
BOOTP application).
2. If NPort 5110 is used in a Static IP environment, you can use NPort 5110 Administration
Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the new IP address.
3. If NPort 5110 is used in a Dynamic IP environment, you can use NPort 5110 Administration
Suite, Web Console, Telnet Console, or Serial Console to configure NPort 5110 to get an IP
address dynamically with DHCP, DHCP/BOOTP, or BOOTP.
ATTENTION
Consult your network administrator on how to reserve a fixed IP address for your NPort 5110 in
the MAC-IP mapping table when using a DHCP Server or BOOTP Server. In most applications,
you should assign a fixed IP address to your NPort 5110.
Factory Default IP Address
NPort 5110 products are configured with the following default private IP address:
Default IP address: 192.168.127.254
(IP addresses of the form 192.168.xxx.xxx are referred to as private IP addresses, since it is not
possible to directly access a device configured with a private IP address from a public network.
For example, you would not be able to ping such a device from an outside Internet connection.
NPort 5110 applications that require sending data over a public network, such as the Internet,
require setting up the server with a valid public IP address, which can be leased from a local ISP.)
NPort 5110 Administration Suite
NPort 5110 Administration Suite consists of some useful utility programs that are used to
configure and manage your NPort 5110s.
See Chapter 5 for details on how to install NPort 5110 Administration Suite, and how to use
this suite of useful utilities to set up IP addresses and configure your NPort 5110 serial device
servers.
ARP
You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for
your NPort 5110. The ARP command tells your computer to associate the NPort 5110’s MAC
address with the intended IP address. You must then use Telnet to access the NPort 5110, at which
point the device server’s IP address will be reconfigured.
ATTENTION
In order to use the ARP setup method, both your computer and NPort 5110 must be connected to
the same LAN. Or, you may use a cross-over Ethernet cable to connect the NPort 5110 directly
to your computer’s Ethernet card. Your NPort 5110 must be configured with the factory default
IP address—192.168.127.254—before executing the ARP command, as described below.

NPort 5110 Series User’s Manual
Initial IP Address Configuration
Take the following steps to use ARP to configure the IP address:
1. Obtain a valid IP address for your NPort 5110 from your network administrator.
2. Obtain NPort 5110’s MAC address from the label on its bottom panel.
3. Execute the ‘arp -s’ command from your computer’s MS-DOS prompt by typing:
arp –s 192.168.200.100 00-90-E8-xx-xx-xx
This is where 192.168.200.100 is the new IP address and 00-90-E8-xx-xx-xx is the MAC
address for your NPort 5110. You will need to change both numbers, as described above in
items 1 and 2.
4. Next, execute a special Telnet command by typing:
telnet 192.168.200.100 6000
After issuing this command, a Connect failed message will appear, as shown here. After the
NPort 5110 reboots, its IP address should be updated to the new address, and you can
reconnect using either Telnet, Web, or Administrator to check that the update was successful.
Telnet Console
Depending on how your computer and network are configured, you may find it convenient to use
network access to set up your NPort 5110’s IP address. This can be done using Telnet.
1. From the Windows desktop, click on Start and then select Run.
2. Type telnet 192.168.127.254 (use the correct IP address if different from the default) in the
Open text input box, and then click OK.
3. When the Telnet window opens, if you are prompted to input the Console password, input the
password and then press Enter. Note that this page will only appear if the NPort 5110 is
password protected.

NPort 5110 Series User’s Manual
Choosing the Proper Operation Mode
Overview
NPort 5110 Serial Device Servers are used to network-enable traditional RS-232 devices. A Serial
Device Server is a tiny computer equipped with a CPU, real-time OS, and TCP/IP protocols that
can bi-directionally transfer data between the serial and Ethernet formats. Your computer can
access, manage, and configure remote facilities and equipment over the Internet from anywhere in
the world.
Traditional SCADA and data collection systems rely on serial ports (RS-232) to collect data from
various kinds of instruments. Since NPort 5110 Serial Device Servers network-enable instruments
equipped with an RS-232 communication port, your SCADA and data collection system will be
able to access all instruments connected to a standard TCP/IP network, regardless of whether the
devices are used locally or at a remote site.
NPort 5110 is an external IP-based network device that allows you to expand the number of serial
ports for a host computer on demand. As long as your host computer supports the TCP/IP protocol,
you won’t be limited by the host computer’s bus limitation (such as ISA or PCI), or lack of drivers
for various operating systems.
In addition to providing socket access, NPort 5110 also comes with a Real COM/TTY driver that
transmits all serial signals intact. This means that your existing COM/TTY-based software can be
preserved, without needing to invest in additional software.
Three different Socket Modes are available: TCP Server, TCP Client, and UDP Server/Client. The
main difference between the TCP and UDP protocols is that TCP guarantees delivery of data by
requiring the recipient to send an acknowledgement to the sender. UDP does not require this type
of verification, making it possible to offer speedier delivery. UDP also allows data to be unicast or
multicast to only one IP or to different groups of IP addresses.
TCP Server Mode
In TCP Server mode, NPort 5110 is configured with a unique IP:Port address on a TCP/IP network.
NPort 5110 waits passively to be contacted by the host computer, allowing the host computer to
establish a connection with and get data from the serial device. This operation mode also supports
up to 4 simultaneous connections, so that multiple hosts can collect data from the same serial
device—at the same time.
As illustrated in the figure, data transmission proceeds as follows:
1. The host requests a connection from the NPort 5110 configured for TCP Server Mode.
2. Once the connection is established, data can be transmitted in both directions—from the host
to the NPort 5110, and from the NPort 5110 to the host.
TCP Client Mode
In TCP Client mode, NPort 5110 can actively establish a TCP connection to a pre-defined host
computer when serial data arrives.
After the data has been transferred, NPort 5110 can automatically disconnect from the host
computer by using the TCP alive check time or Inactivity time settings. Refer to Chapter 5 for
more details.
Data transmission proceeds as follows:
1. The NPort 5110 configured for TCP Client Mode requests a connection from the host.
2. Once the connection is established, data can be transmitted in both directions—from the host
to the NPort 5110, and from the NPort 5110 to the host.

NPort 5110 Series User’s Manual
Choosing the Proper Operation Mode
UDP Mode
Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you can
unicast or multicast data from the serial device to one or multiple host computers, and the serial
device can also receive data from one or multiple host computers, making this mode ideal for
message display applications.
Real COM Mode
NPort 5110 comes equipped with COM drivers that work with Windows 95/98/ME/NT/2000/XP
systems, and also TTY drivers for Linux systems. The driver establishes a transparent connection
between host and serial device by mapping the IP:Port of the NPort 5110 port to a local COM port
on the host computer. This operation mode also supports up to 4 simultaneous connections, so that
multiple hosts can collect data from the same serial device at the same time.
ATTENTION
The driver used for Real COM Mode is installed automatically on your computer when you
install NPort 5110 Administration Suite.
One of the major conveniences of using Real COM Mode is that Real COM Mode allows users to
continue using RS-232 serial communications software that was written for pure serial
communications applications. The driver intercepts data sent to the host’s COM port, packs it into
a TCP/IP packet, and then redirects it through the host’s Ethernet card. At the other end of the
connection, the NPort 5110 accepts the Ethernet frame, unpacks the TCP/IP packet, and then
transparently sends it to the appropriate serial device attached to one of the NPort 5110’s serial
ports.
ATTENTION
Real COM Mode allows several hosts to have access control of the same NPort 5110. The driver
that comes with your NPort 5110 controls host access to attached serial devices by checking the
host’s IP address. Refer to Accessible IP Settings in Chapter 5 for more details.
Pair Connection Mode
Pair Connection Mode employs two NPort 5110 device servers in tandem, and can be used to
remove the 15-meter distance limitation imposed by the RS-232 interface. One NPort 5110 is
connected from its RS-232 port to the COM port of a PC or other type of computer, such as
hand-held PDAs that have a serial port, and the serial device is connected to the RS-232 port of the
other NPort 5110. The two NPort 5110 are then connected to each other with a cross-over Ethernet
cable, both are connected to the same LAN, or in a more advanced setup, they communicate with
each other over a WAN (i.e., through one or more routers). Pair Connection Mode transparently
transfers both data and modem control signals (although it cannot transmit the DCD signal)
between the two NPorts.

Choosing the Proper Operation Mode
Ethernet Modem Mode
The Ethernet Modem operation mode is designed for use with legacy operating systems, such as
MS-DOS, that do not support TCP/IP Ethernet. By connecting one NPort 5110’s serial port to the
MS-DOS computer’s serial port, it is possible to use legacy software originally designed to transmit
data via modem, but now transmit the data over the Ethernet.

You must assign a valid IP address to NPort 5110 before it will work in your network environment.
Your network system administrator should provide you with an IP address and related settings for
your network. The IP address must be unique within the network (otherwise, NPort 5110 will not
have a valid connection to the network). First time users can refer to Chapter 3, “Initial IP Address
Configuration,” for more information.
You can choose from four possible “IP configuration” modes—Static, DHCP, DHCP/BOOTP,
and BOOTP—located under the web console screen’s IP configuration drop-down box.

An IP address is a number assigned to a network device (such as a computer) as a permanent
address on the network. Computers use the IP address to identify and talk to each other over the
network. Choose a proper IP address which is unique and valid in your network environment.

A subnet mask represents all of the network hosts at one geographic location, in one building, or
on the same local area network. When a packet is sent out over the network, the NPort 5110 will
use the subnet mask to check whether the desired TCP/IP host specified in the packet is on the
local network segment. If the address is on the same network segment as the NPort 5110, a
connection is established directly from the NPort 5110. Otherwise, the connection is established
through the given default gateway.
Gateway

A gateway is a network gateway that acts as an entrance to another network. Usually, the
computers that control traffic within the network or at the local Internet service provider are
gateway nodes. NPort 5110 needs to know the IP address of the default gateway computer in order
to communicate with the hosts outside the local network environment. For correct gateway IP
address information, consult the network administrator.

connect to the web server. DNS is the way that Internet domain names are identified and translated
into IP addresses. A domain name is an alphanumeric name, such as moxa.com, that it is usually
easier to remember. A DNS server is a host that translates this kind of text-based domain name
into the numeric IP address used to establish a TCP/IP connection.
In order to use NPort 5110’s DNS feature, you need to configure the DNS server. Doing so allows
NPort 5110 to use a host’s domain name to access the host. NPort 5110 provides DNS server 1
and DNS server 2 configuration items to configure the IP address of the DNS server. DNS Server
2 is included for use when DNS sever 1 is unavailable.
NPort 5110 plays the role of DNS client, in the sense that the NPort 5110 will actively query the
DNS server for the IP address associated with a particular domain name. NPort 5110 functions that
support domain name are Time server, Destination IP Address in TCP Client mode, Mail
Server, SNMP trap server, and Auto report to IP.

IP Address Report
When NPort 5110 products are used in a dynamic IP environment, users must spend more time
with IP management tasks. For example, if NPort 5110 works as a server (TCP or UDP), then the
host, which acts as a client, must know the IP address of the server. If the DHCP server assigns a
new IP address to NPort 5110, the host must have some way of determining NPort 5110’s new IP
address.
NPort 5110 products help out by periodically reporting their IP address to the IP location server, in
case the dynamic IP has changed. The parameters shown below are used to configure the Auto IP
report function. There are two ways to develop an “Auto IP report Server” to receive NPort 5110’s
Auto IP report.
1.
2.
Use Device Server Administrator’s IP Address Report function.
“Auto IP report protocol”, which can automatically receive the Auto IP report on a regular
basis, is also available to help you develop your own software. Refer to Appendix E for the
“Auto IP report protocol”.

Max connection 2 to 4:
Allows 2 to 4 host’s Real COM drivers to open the specific NPort 5110 serial port, at the same
time. When multiple hosts’ Real COM drivers open the serial port at the same time, the COM
driver only provides a pure data tunnel without control ability. That is, this serial port parameter
will use firmware’s settings, not depend on your application program (AP).
Application software that is based on the COM driver will receive a driver response of “success”
when the software uses any of the Win32 API functions. The firmware will only send the data
back to the driver on the host.
Data will be sent first-in-first-out when data comes into the NPort 5110 from the Ethernet
interface.
ATTENTION
When Max connection is set to 2, 3, or 4, this means that NPort 5110 will be using a “multi
connection application” (i.e., 2, 3, or 4 hosts are allowed access to the port at the same time).
When using a multi connection application, NPort 5110 will use the serial communication
parameters set in the console. All of the hosts connected to that port must use the same serial
settings. If one of the hosts opens the COM port with parameters that are different from NPort
5110’s console setting, data communication may not work properly.

Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer. If the size
of the serial data received is greater than 1 KB, the NPort 5110 will automatically pack the data

buffer is full or if the Force transmit time interval reaches the time specified under Force transmit
timeout.
The optimal Force transmit timeout depends on your application, but it must be at least larger than
one character interval within the specified baud rate. For example, assume that the serial port is set
to 1200 bps, 8 data bits, 1 stop bit, and no parity. In this case, the total number of bits needed to
send a character is 10 bits, and the time required to transfer one character is
( 10 (bits) / 1200 (bits/s) ) * 1000 (ms/s) = 8.3 ms.
Therefore, you should set Force transmit timeout to be larger than 8.3 ms, so in this case, it must
be greater than or equal to 10 ms.
If the user wants to send a series of characters in the same packet, the serial device attached to
NPort 5110 should send that series of characters during a time interval less than the Force transmit
timeout for NPort 5110, and the total length of data must be less than or equal to NPort 5110’s
internal buffer size. The serial communication buffer size for NPort 5110 is 1 KB per port.

for the given time. After the connection is closed, NPort 5110 starts listening for another host’s
TCP connection.
This parameter defines the maintenance status as Closed or Listen for the TCP connection. The
connection is closed if there is no incoming or outgoing data through the serial port during the
specific Inactivity time.
If the Inactivity time is set to 0, the current TCP connection is kept active until a connection close
request is received. Although Inactivity time is disabled, the NPort 5110 will check the connection
status between the NPort 5110 and remote host by sending “keep alive” packets periodically. If the
remote host does not respond to the packet, NPort 5110 assumes that the connection was closed
down unintentionally. NPort 5110 will then force the existing TCP connection to close.
ATTENTION
The Inactivity time should at least be set larger than that of Force transmit timeout. To prevent
the unintended loss of data due to the session being disconnected, it is highly recommended that
this value is set large enough so that the intended data transfer is completed.

Ethernet Modem
Dial-in
NPort 5110 listens for a TCP/IP connection request from the remote Ethernet modem or host.
NPort 5110’s response depends on the ATS0 value, as outlined below.
ATS0=0 (default):
NPort 5110 will temporarily accept the TCP connection and then send the “RING” signal out through
the serial port. The serial controller must reply with “ATA” within 2.5 seconds to accept the connection
request, after which NPort 5110 enters data mode. If no “ATA” command is received, NPort 5110 will
disconnect after sending three “RING” signals.
ATS0≧1:
NPort 5110 will accept the TCP connection immediately and then send the “CONNECT <baud>”
command to the serial port, in which <baud> represents the baud rate of NPort 5110’s serial port. After
that, NPort 5110 immediately enters data mode.
Dial-out
NPort 5110 accepts the AT command “ATD <IP>:<TCP port>” from the serial port and then
requests a TCP connection from the remote Ethernet Modem or PC. This is where <IP> is the IP
address of the remote Ethernet modem or PC, and <TCP port> is the TCP port number of the
remote Ethernet modem or PC. Once the remote unit accepts this TCP connection, NPort 5110
will send out the “CONNECT <baud>” signal via the serial port and then enter data mode.
Disconnection request from local site
When NPort 5110s is in data mode, the user can drive the DTR signal to OFF, or send “+++” from
the local serial port to NPort 5110. NPort 5110 will enter command mode and return “NO
CARRIER” via the serial port, and then input “ATH” to shut down the TCP connection after 1
second.
The “+++” command cannot be divided. The “+” character can be changed in register S2, and
the guard time, which prefixes and suffixes the “+++” in order to protect the raw data, can be
changed in register S12.

COM Mapping
Windows Administration Suite comes with Windows 95/98/ME/NT/2000/XP Real COM drivers.
After you install NPort 5110 Administration Suite, there are two ways to set up the NPort 5110’s
serial port as your host’s remote COM port.
The first way is with On-line COM Mapping. On-line COM Mapping will check to make sure
that the NPort 5110 is connected correctly to the network, and then install the driver on the host
computer.
The second way is with Off-line COM Installation, without connecting the NPort 5110 to the
network first. Off-line COM Mapping can decrease the system integrator’s effort by solving
different field problems. Via off-line installation, users can process the host software installation
and then install the NPort 5110 to different fields.
Use the following procedure to map COM ports:
1. On-line COM Mapping:
Connect NPort 5110 to the network $ Set NPort 5110 to the proper IP address $ Map
COMs to your host $ Apply Change.
2. Off-line COM Mapping:
Map COMs to your host $ Apply Change $ Connect NPort 5110 to the network $
Configure NPort 5110’s IP address.
On-line COM Mapping
1. Broadcast Search for NPort 5110s on the network.
2. Select the COM Mapping function group.

the NPort 5110 that you would like to map COM ports to.
5. Select COM Settings to modify COM No., default setting, etc.

6. Select the COM No. COM ports that are “In use” or “Assigned” will also be indicated in this
drop-down list. If you select multiple serial ports or multiple NPort 5110s, remember to check
the “Auto Enumerating” function to use the COM No. you select as the first COM No.
Hi-performance mode is the default for Tx mode. If the driver finishes sending data out to
the NPort 5110, the driver will respond to the program with “Tx Empty.”
Under classical mode, the driver will not notify the user’s program that the Tx is finished until
all Tx data has been sent out from the NPort 5110; this mode will cause lower throughput.
Classical mode is recommended if you want to ensure that all data is sent out before doing
more processing,.

Enable/Disable Tx/Rx FIFO. If disabled, NPort 5110 will send one byte each time the Tx
FIFO becomes empty; and an Rx interrupt will be generated for each incoming byte. This will
result in a faster response and lower throughput. If you want to use XON/XOFF flow control,
we recommend setting FIFO to Disable.
Fast Flush (only flush local buffer)
! We have added one optional Fast Flush function to Moxa’s new NPort Real COM driver.
The new function is available in versions 1.2 and higher of NPort Administrator Suite
for NPort.
! For some applications, the user’s program will use the Win32 “PurgeComm()” function
before it reads or writes data. With our design, after the program uses this Purge Comm()
function, the NPort driver will keep querying NPort’s firmware several times to make sure
there is really no data queued in the NPort firmware buffer, rather than just flushing the
local buffer. This kind of design is used because of some special considerations. However,
it might take more time (about several hundred milliseconds) than a native COM1, because
it needs to work via Ethernet. That’s why the native COM ports on the motherboard can
work fast with this function call, but NPort requires much more time. In order to
accommodate other applications that require a faster response time, the new NPort driver
implements a new “Fast Flush” option. Note that by default, this function is disabled.
! To begin with, make sure there are some “PurgeComm()” functions being used in your
application program. In this kind of situation, you might find that your NPort exhibits a
much poorer operation performance than when using the native COM1 port. Once you have
enabled the “Fast Flush” function, you can check to see if there has been an improvement
in performance.
! By default, the optional “Fast Flush” function is disabled. If you would like to enable this
function, from the “NPort Administrator,” double click on the COM ports that are mapped
to the NPort, and then select the “Fast Flush” checkbox. You should find that when “Fast
Flush” is enabled, the NPort driver will work faster with “PurgeComm().”

in the host system registry. The host computer will not have the ability to use the COM port
until after Apply Change is selected.

IP Serial LIB
Overview
What is IP Serial Library?
IP Serial Library is a Windows library with frequently used serial command sets and subroutines.
IP Serial Library is designed to reduce the complexity and poor efficiency of serial communication
over TCP/IP. For example, Telnet can only transfer data, but it can’t monitor or configure the
serial line’s parameters.
Why Use IP Serial Library?
For programmers who are familiar with serial communication, IP Serial Library provides
well-designed function calls that have the same style as Moxa’s PComm Library.
IP Serial Library is amazingly simple and easy to understand. By including it in your VB, C, or
Delphi programming environment, you can program your own TCP/IP application with the ability
to control serial communication parameters.
NPort 5110 uses 2 TCP ports for communication between the NPort 5110 and host computer’s
Real COM driver. NPort 5110 uses a data port and command port to provide pure data transfer
without decode and encode. Compared to using only one TCP port to control serial
communication (such as RFC 2217), IP Serial Library uses a command port to communicate with
NPort 5110 from the user’s program. IP Serial Library not only runs with excellent efficiency but
also runs without any decode or encode problems.
How to install IP Serial Library
IP Serial Lib comes with the NPort 5110 Administration Suite. Refer to the IPSerial directory for
more details about the function definitions.

Well Known Port Numbers
In this appendix, which is included for your reference, we provide a list of Well Known port
numbers that may cause network problems if you set NPort 5110 to one of these ports. Refer to
RFC 1700 for Well Known port numbers, or refer to the following introduction from the IANA.
The port numbers are divided into three ranges: the Well Known Ports, the Registered Ports,
and the Dynamic and/or Private Ports.
The Well Known Ports range from 0 through 1023.
The Registered Ports range from 1024 through 49151.
The Dynamic and/or Private Ports range from 49152 through 65535.
The Well Known Ports are assigned by the IANA, and on most systems, can only be used by
system processes or by programs executed by privileged users. The following table shows famous
port numbers among the well-known port numbers. For more details, please visit the IANA

Auto IP Report Protocol
NPort Series provides several ways to configure Ethernet IP addresses. One method is DHCP
Client. When you set up the NPort to use DHCP Client to configure Ethernet IP addresses, a
DHCP request is sent automatically over the Ethernet to find the DHCP Server. In response, the
DHCP Server will send an available IP address to the NPort. The NPort will use this IP address for
a period of time after receiving it. But the NPort will eventually send another DHCP request to the
DHCP Server. Once the DHCP Server realizes that this IP address is to be released to other DHCP
Clients, the NPort will be assigned a different IP address. For this reason, users sometimes find
that the NPort will use different IP addresses at different, instead of always using the same IP
address.
In order to find out which IP address the NPort is using, you need to configure parameters under
Network Settings via your Web browser. The figure below shows NPort’s Web console
configuration window. Enter the IP address and the Port number of the PC that you want to send
this information to.
