Overview
The NPort IA5150/5250 series of device servers deliver easy and reliable serial-to-Ethernet
connectivity for the industrial automation market. The NPort IA5150/5250 series is designed to
allow any serial device to connect to an Ethernet network. The compact size of NPort IA device
servers makes them an ideal choice for connecting RS-232/422/485 serial devices, such as PLCs,
sensors, meters, motors, drives, barcode readers, and operator displays. The NPort IA5150/5250
Series device servers come with a compact and rugged DIN-Rail mountable casing.
NPort IA serial device servers ensure the compatibility of network software that uses a standard
network API (Winsock or BSD Sockets) by providing five modes: TCP Server, TCP Client, UDP,
Pair Connection, Ethernet Modem, and Rtelnet. Thanks to NPort IA5150/5250 series’ Real
COM/TTY drivers, software that works with COM/TTY ports can be set up to work over a
TCP/IP network, without modifying the serial COM software applications. This excellent feature
preserves your software investment and lets you enjoy the benefits of networking your serial
devices instantly.
NPort IA serial device servers support automatic IP configuration protocols (DHCP, BOOTP) and
manual configuration via a handy web browser console. Both methods ensure quick and effective
installation. And with NPort IA5150/5250’s Windows Utility, installation is very straightforward,
since all system parameters can be stored and then copied to other device servers simultaneously.

Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your NPort IA5150/5250
Series.
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 NPort IA5150/5250. When plugged in, NPort IA5150/5250’s
internal components generate heat, and consequently the casing may feel hot to the touch. When
installed with other components, make sure that there is at least 2 cm clearance on all sides of
NPort IA5150/5250 in order to allow proper heat dissipation.
You should heed the following:
yUse 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.
yYou 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.
yKeep input wiring and output wiring separate.
yWhere 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 IA5150/5250’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.

NPort IA5150/5250 Series User’s Manual Getting Started
2-4
Grounding the NPort IA5150/5250 Series
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.
WARNING
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 IA5150/5250’s 10/100M Ethernet port and the
other end of the cable to the Ethernet network. If the cable is properly connected, the NPort
IA5150/5250 will indicate a valid connection to the Ethernet in the following ways:
yThe Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet
network.
yThe 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.
ATTENTION
NPort IA5150 and NPort IA5250 each have 2 Ethernet ports, which can be used to create an
open chain of NPort IA device servers. You must be careful not to connect the Ethernet ports of
the two device servers at the ends of the chain. In other words, NPort IA does NOT support a
closed chain.
Connecting to a Serial Device
Connect the serial data cable between NPort IA5150/5250 and the serial device. Serial data cables
are optional accessories for NPort.

NPort IA5150/5250 Series User’s Manual Getting Started

Chapter 3 Initial IP Address Configuration
When setting up your NPort IA5150/5250 for the first time, the first thing you should do is
configure the IP address. This chapter introduces the methods that can be used to configure the
device server’s IP address. Select one of the initial IP Address configuration methods to
configure NPort IA5150/5250’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
NPort Administration Suite
ARP
Telnet Console
Serial Console (19200, n, 8, 1)

NPort IA5150/5250 Series User’s Manual Initial IP Address Configuration
3-2
Initializing the NPort’s IP Address
1. Determine whether your NPort IA5150/5250 needs to use a Static IP or Dynamic IP (either
DHCP or BOOTP application).
2. If NPort IA5150/5250 is used in a Static IP environment, you can use NPort IA5150/5250
Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the
new IP address.
3. If NPort IA5150/5250 is used in a Dynamic IP environment, you can use NPort
IA5150/5250 Administration Suite, Web Console, Telnet Console, or Serial Console to
configure NPort IA5150/5250 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
IA5150/5250 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 IA5150/5250.
Factory Default IP Address
NPort IA5150/5250 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 IA5150/5250 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 Administration Suite
NPort Administration Suite consists of some useful utility programs that are used to configure and
manage your NPort IA5150/5250.
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 IA5150/5250 Series
serial device servers.
ARP
You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for
your NPort IA5150/5250. The ARP command tells your computer to associate the NPort
IA5150/5250’s MAC address with the intended IP address. You must then use Telnet to access the
NPort IA5150/5250, at which point the device server’s IP address will be reconfigured.

3-3
ATTENTION
In order to use this setup method, both your computer and NPort IA5150/5250 must be
connected to the same LAN. Or, you may use a cross-over Ethernet cable to connect the NPort
IA5150/5250 directly to your computer’s Ethernet card. Before executing the ARP command,
your NPort IA5150/5250 must be configured with the factory default IP address
(192.168.127.254), and your computer and the NPort IA must be on the same subnet.
Take the following steps to use ARP to configure the IP address:
1. Obtain a valid IP address for your NPort IA5150/5250 from your network administrator.
2. Obtain the NPort IA5150/5250’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 IA5150/5250. (Be sure to use the actual IP address and MAC address for your
NPort IA5150/5250.)
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.

Depending on how your computer and network are configured, you may find it convenient to use
network access to set up your NPort IA5150/5250’s IP address. This can be done using Telnet.
