Welcome to the MOXA NPort 5400 Series of advanced serial device servers, which make it easy
to enable network operation of your serial devices. All device servers in the series come with four
serial ports. On the NPort 5410, the serial ports are RS-232 ports; on the NPort 5430/5430I, the
serial ports are RS-422/485 ports; on the NPort 5450/5450I, the serial ports are RS-232/422/485
ports.
NPort 5400 Series device servers are designed to make your industrial serial devices Internet ready
instantly. The compact size of NPort 5400 device servers makes them the ideal choice for
connecting RS-232/422/485 serial devices—such as PLCs, meters, and sensors—to an IP-based
Ethernet LAN, making it possible for your software to access serial devices anywhere over a local
LAN or the Internet.
NPort 5400 serial device servers ensure the compatibility of network software that uses a standard
network API (Winsock or BSD Sockets) by providing TCP Server Mode, TCP Client Mode, and
UDP Mode. And thanks to the NPort’s Real COM/TTY drivers, software that works with
COM/TTY ports can be set up to work over a TCP/IP network in no time. This excellent feature
preserves your software investment and lets you enjoy the benefits of networking your serial
devices instantly.
NPort 5400 serial device servers support automatic IP configuration protocols (DHCP, BOOTP)
and manual configuration via the NPort’s handy web browser console. Both methods ensure quick
and effective installation. And with the NPort 5400’s Windows Utility, installation is very
straightforward, since all system parameters can be stored and then copied to other device servers
simultaneously.

This section describes how to connect the NPort 5400 to serial devices for first time testing
purposes. We cover Wiring Requirements, Connecting the Power, Grounding the NPort 5400 Series, Connecting to the Network, Connecting to a Serial Device, and LED Indicators.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your NPort 5400.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
Temperature Caution!
Please take care when handling the NPort 5400. When plugged in, the NPort 5420/5430/5430I’s
internal components generate heat, and consequently the casing may feel hot to the touch.
You should also heed the following:
y Use separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit.
To avoid interference, wires with different signal characteristics should be routed separately.
y You can use the type of signal transmitted through a wire to determine which wires should be
kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can
be bundled together.
y Keep input wiring and output wiring separate.
y Where necessary, it is strongly advised that you label wiring to all devices in the system.
Connecting the Power
Connect the 12-48 VDC power line with the NPort 5400’s terminal block. If the power is properly
supplied, the “Ready” LED will show a solid red color until the system is ready, at which time the
“Ready” LED will change to a green color.
Grounding the NPort 5400
Grounding and wire routing helps limit the effects of noise caused by electromagnetic interference
(EMI). Run the ground connection from the ground screw to the grounding surface prior to
connecting devices.

NPort 5400 Series User’s Manual Getting Started
ATTENTION
This product is intended to be mounted to a well-grounded mounting surface such as a metal
panel.
SG: The Shielded Ground (sometimes called Protected Ground)
contact is the left most contact of the 3-pin power terminal
block connector when viewed from the angle shown here.
Connect the SG wire to an appropriate grounded metal
surface.
Connecting to the Network
Connect one end of the Ethernet cable to the NPort 5400’s 10/100M Ethernet port and the other
end of the cable to the Ethernet network. If the cable is properly connected, the NPort 5400 will
indicate a valid connection to the Ethernet in the following ways:
y The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet
network.
y The Ethernet LED maintains a solid yellow color when connected to a 10 Mbps Ethernet
network.
yThe Ethernet LED will flash when Ethernet packets are being transmitted or received.
Connecting to a Serial Device
Connect the serial data cable between the NPort 5400 and the serial device.
LED Indicators
The top panels of the NPort 5400 have four LED indicators, as described in the following table.

Adjustable Pull High/low Resistors for the RS-485 Port
In some critical environments, you may need to add termination resistors to prevent the reflection of
serial signals. When using termination resistors, it is important to set the pull high/low resistors
correctly so that the electrical signal is not corrupted. Since there is no resistor value that works for
every environment, DIP switches are used to set the pull high/low resistor values for each RS-485
port.
To set the pull high/low resistors to 150 KΩ, make sure both of the assigned DIP switches are in
the OFF position. This is the default setting.
To set the pull high/low resistors to 1 KΩ, make sure both of the assigned DIP switches are in the
ON position.

ATTENTION
Do not set the resistors to 1 KΩ when using RS-232. Doing so will degrade the RS-232 signals
and reduce the effective communication distance.

Chapter 3 Initial IP Address Configuration
When setting up your NPort 5410/5430/5430I/5450/5450I for the first time, the first thing you
should do is configuring the IP address. This chapter introduces the method to configure the
NPort’s IP address. Select one of the initial IP Address configuration methods to configure the NPort’s IP Address. For more details about network settings, see the Network Settings section
from Chapter 5, Web Console Configuration.
This chapter includes the following sections:
Initializing the NPort’s IP Address
Factory Default IP Address
LCM Display Å recommended configuration method
NPort Administration Suite Å recommended configuration method
ARP
Telnet Console
NPort 5400 Series User’s Manual Initial IP Address Configuration
Initializing the NPort’s IP Address
1. Determine whether your NPort needs to use a Static IP or Dynamic IP (either DHCP or
BOOTP application).
2. If the NPort is used in a Static IP environment, you can use LCM Display, NPort
Administration Suite, ARP, Web Console, or Telnet Console to configure the new IP address.
3. If the NPort is used in a Dynamic IP environment, you can use LCM Display, NPort
Administration suite, Web Console, or Telnet Console to configure the NPort 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 5400 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.
Factory Default IP Address
NPort products are configured with the following default private IP address:
(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 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.)
LCM Display
We recommend using LCM display and four push buttons to configure the IP address at the first
time installation.
Basic Operation
If the NPort is working properly, the LCM panel will display a green color. The red Ready LED
will also light up, indicating that the NPort is receiving power. After the red Ready LED turns to
green, you will see a display similar to:
NPort 5400 Series User’s Manual Initial IP Address Configuration
There are four push buttons on the NPort’s nameplate. Going from left to right, the buttons are:
Button Name
MENU menu activates the main menu, or returns to a lower level
U
V
SEL
up cursor
down cursor scrolls down through a list of items shown on the LCM panel’s second line
select
Action
scrolls up through a list of items shown on the LCM panel’s second line
selects the option listed on the LCM panel’s second line
The buttons are manipulated in a manner similar to the way a modern cellular phone operates. As
you move through the various functions and setting options, note that the top line shows the
current menu or submenu name, and the bottom line shows the submenu name or menu item
which is activated by pressing the SEL button.
Detailed Menu Options
The best way to explain all of the NPort’s LCM functions is to refer to the tree graph shown in the
next page. There are three main levels—1, 2, and 3—with each level represented by a separate
column.
The first thing to remember is that the menu button is used to move back and forth between the
LCM panel’s default screen, and main menu screen:
• Use the SEL button to move up one level (i.e., left to right on the tree graph)
• Use the MENU button to move down one level (i.e., right to left on the tree graph)
• Use the cursor keys, U and V, to scroll between the various options within a level (i.e.,
up and down on the tree graph).
As you use the buttons to operate the LCM display, you will notice that with very few
exceptions, moving up one level causes the bottom line of the display to move to the top
line of the display. You will also notice that the bottom three options in level 2, and all of
the options in level 3 have either a C or D attached.
The meaning is as follows:
• C = configurable
I.e., you are allowed to change the setting of this option
• D = display only
I.e., the setting for this option is displayed, but it cannot be changed (this does NOT
necessarily mean that the number doesn’t change; only that you can’t change it)

The part of the LCM operation that still requires some explanation is how to edit the
configurable options. In fact, you will only encounter two types of configurable options.
The first type involves entering numbers, such as IP addresses, Netmasks, etc. In this case,
you change the number one digit at a time. The up cursor (U) is used to decrease the
highlighted digit, the down cursor (V) is used to increase the highlighted digit, and the
SEL button is used to move to the next digit. When the last digit has been changed,
pressing SEL simply enters the number into the NPort Server Lite’s memory.
3-4
NPort 5400 Series User’s Manual Initial IP Address Configuration
The second type of configurable option is when there are only a small number of options
from which to choose (although only one option will be visible at a time). Consider the
PARITY attribute under PORT SETTING as an example. Follow the tree graph to arrive at
the following PARITY screen. The first option, NONE, is displayed, with a down arrow all
the way to the right. This is an indication that there are other options from which to choose.

NPort Administration Suite
NPort Administration Suite consists of some useful utility programs that are used to configure and
manage your NPort device server.
See Chapter 5 for details on how to install NPort Administration Suite, and how to use this
suite of useful utilities to set up IP addresses and configure your NPort.
ARP
You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for
your NPort. The ARP command tells your computer to associate the NPort’s MAC address with
the intended IP address. You must then use Telnet to access the NPort, at which point the device
server’s IP address will be reconfigured.
ATTENTION
In order to use this setup method, both your computer and the NPort must be connected to the
same LAN.
Or, you may use a cross-over Ethernet cable to connect the NPort directly to your computer’s
Ethernet card.
Your NPort must be configured with the factory default IP address—192.168.127.254—before
executing the ARP command, as described below.
3-5
NPort 5400 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 from your network administrator.
2. Obtain the NPort’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. You will need to change both numbers, as described above in points 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 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’s IP address. This can be done using the Telnet program.
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 is password protected.
3-6
NPort 5400 Series User’s Manual Initial IP Address Configuration
4. Type 2 to select Network settings, and then press Enter.
5. Type 1 to select IP address and then press Enter.
6. Use the Backspace key to erase the current IP address, type in the new IP address, and then
press Enter.

Chapter 4 Choosing the Proper Operation Mode
In this chapter, we describe the various NPort 5400 operation modes. The options include an
operation mode that uses a driver installed on the host computer, and operation modes that rely on
TCP/IP socket programming concepts. After choosing the proper operation mode in this chapter,
refer to Chapter 5 for detailed configuration parameter definitions.
The following topics are covered in this chapter:
Overview
Real COM Mode
TCP Server Mode
TCP Client Mode
UDP Mode
Pair Connection Mode
Reverse Telnet Mode
Disabled Mode
NPort 5400 Series User’s Manual Choosing the Proper Operation Mode
Overview
NPort device servers enable network operation of traditional RS-232/422/485 devices, in which a
device server is a tiny computer equipped with a CPU, real-time OS, and TCP/IP protocols that
can bi-directionally translate 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-232/422/485) to collect
data from various kinds of instruments. Since NPort serial device servers enable network operation
of instruments equipped with an RS-232/422/485 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.
The NPort 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, the NPort 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 multicasting of data
to groups of IP addresses.
ATTENTION
Pictures in this Chapter will use the NPort 5400 as an example.
Real COM Mode
The NPort 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’s serial port to a local
COM/TTY 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.
4-2
NPort 5400 Series User’s Manual Choosing the Proper Operation Mode
ATTENTION
The driver used for Real COM Mode comes with the NPort Windows Administrator. The driver
is installed automatically on your computer when you install NPort Administration Suite.
The important point is that Real COM Mode allows users to continue using RS-232/422/485 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 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’s serial ports.
ATTENTION
Real COM Mode allows several hosts to have access control over the same NPort. The driver
that comes with your NPort controls host access to attached serial devices by checking the host’s
IP address.
Modify the Accessible IP Setting table when the legal IP address should be required in your
application
TCP Server Mode
In TCP Server mode, the NPort provides a unique IP:Port
address on a TCP/IP network. The NPort 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
configured for TCP Server Mode.
2. Once the connection is established, data can be
transmitted in both directions—from the host to the
NPort, and from the NPort to the host.
4-3
NPort 5400 Series User’s Manual Choosing the Proper Operation Mode
TCP Client Mode
In TCP Client mode, the NPort can actively
establish a TCP connection to a pre-defined host
computer when serial data arrives.
After the data has been transferred, the NPort 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.
As illustrated in the figure, data transmission
proceeds as follows:
1. The NPort 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, and from the NPort to the host.
UDP Mode
Compared to TCP communication, UDP is
faster and more efficient. In UDP mode, you can
multicast data from the serial device to multiple
host computers, and the serial device can also
receive data from multiple host computers,
making this mode ideal for message display
applications.
Pair Connection Mode
Pair Connection Mode employs two NPort 5400 units in tandem, and can be used to remove the
15-meter distance limitation imposed by the RS-232 interface. One NPort 5400 is connected from
its RS-232 port to the COM port of a PC or other type of computer, such as a hand-held PDA, and
the serial device is connected to the RS-232 port of the other NPort 5400. The two NPort 5400
units 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 NPort device servers.
4-4
NPort 5400 Series User’s Manual Choosing the Proper Operation Mode
Reverse Telnet Mode
Console management is commonly used by connecting to Console/AUX or COM ports of routers,
switches, and UPS units. Rtelnet works the same as RAW mode in that only one TCP port is
listened to after booting up. The system then waits for a host on the network to initiate a
connection. The difference is that the RAW mode does not provide the conversion function
provided by Telnet. If the connected devices need to use the CR/LF conversion function when
controlling, then users must choose Rtelnet mode.
Disabled Mode
When the Operation Mode for a particular port is set to Disabled, that port will be disabled.

Chapter 5 Web Console Configuration
The Web Console is the most user-friendly way to configure the NPort 5410/5430/5430I. This
chapter will introduce the Web Console function groups and function definitions. This chapter
uses the NPort 5230 as an example. The function and definition is totally the same with NPort
5400 series devices servers.

NPort 5400 Series User’s Manual Web Console Configuration
ATTENTION
Refer to Chapter 3, “Initial IP Address Configuration,” to see how to configure the IP address.
Examples shown in this chapter use the Factory Default IP address (192.168.127.254).
The NPort 5410/5430/5430I/5450/5450I homepage will open. On this page, you can see a brief
description of the Web Console’s nine function groups.
ATTENTION
If you can’t remember the password, the ONLY way to start configuring the NPort is to load
factory defaults by using the Reset button located near the NPort’s RJ45 Ethernet port.
Remember to use NPort Administrator to export the configuration file when you have finished
the configuration. After using the Reset button to load factory defaults, your configuration can be
easily reloaded into the NPort by using the NPort Administrator Import function. Refer to
Chapter 6 for more details about using the Export and Import functions.
ATTENTION
If your NPort application requires using password protection, you must enable the cookie
function in your browser. If the cookie function is disabled, you will not be allowed to enter the
Web Console Screen.

change. The console will display the real time according to the time zone. To modify the real time
clock, click on Modify next to the Local time field. Once you submit the new time, the NPort
5400’s firmware will modify the GMT time according to your time zone and local time settings.
