Connecting the Hardware
This section describes how to connect the NPort IA5150A/IA5250A to serial devices for first time testing
purposes. We cover Wiring Requirements, Connecting the Power, Grounding the NPort
IA5150A/IA5250A 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 IA5150A/IA5250A
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 the NPort IA5150A/IA5250A. When plugged in, the NPort IA5150A/IA5250A’s
internal components generate heat, and consequently the casing may feel hot to the touch. When
inst
alled
with other components, make sure that there is at least 2 cm clearance on all sides of
the NPort
IA5150A/IA5250A in order to allow proper heat dissipation.
You should heed the following:
•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.
•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.
•Keep input wiring and output wiring separate.
•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 IA5150A/IA5250A’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 IA5150A/IA5250A 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 mounte
d to a well-grounded mounting surface such as a metal panel.

NPort IA5150A/IA5250A Series Getting Started
2-4
SG:
The Shielded Ground (sometimes called Protected Ground) contact
is the l
eft most contact of the 8 contact 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 IA5150A/IA5250A’s 10/100M Ethernet port and the other
end of the cable to the Ethernet network. If the cable is properly connected, the NPort IA5150A/IA5250A will
indicate a valid connection to the Ethernet in the following ways:
•The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet network.
•The Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet network.
•The Ethernet LED will flash when Ethernet packets are being transmitted or received.
ATTENTION
Every NPort IA5150A/ IA5250A series is equipped with 2 Ethernet ports, which can be used to create an
open
chain of NPor
t IA5150A/IA5250A 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 the NPort IA5150A/IA5250A and the serial device. Serial data cables are
optional accessories for NPort.
LED Indicators
The top panels of all NPort IA5150A/IA5250As have four LED indicators, as described in the following table.
LED Name LED Color LED Function
PWR1, PWR2
red
Power is being supplied to power input PWR1, PWR2.
Ready red Steady on: Power is on and the NPort IA5150A/IA5250A is booting up.
Blinking: Indicates an IP conflict, or DHCP or BOOTP server did not
respond properly, or a relay output occurred.
When the above two conditions occur at the same time,
check the relay output first. If after resolving the relay output
the Ready LED is still blinking, then there is an IP conflict, or
the DHCP or BOOTP server did not respond properly.
green Steady on: Power is on and the NPort IA5150A/IA5250A is functioning
normally.
Blinking: The device server has been located by Administrator’s
Location function.
off Power is off, or power error condition exists.
E1, E2 orange 10 Mbps Ethernet connection.
green 100 Mbps Ethernet connection.
off Ethernet cable is disconnected, or has a short.
P1, P2 orange Serial port is receiving data.
green Serial port is transmitting data.
off No data is being transmitted or received through the serial port.

Adjust the Pull-high/Pull-low Resistors and Terminators for
RS-422/RS-485 Ports
In certain 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 properly so that
electrical signals do not become corrupted. It is improbable for a single pull high/low resistor value to suit all
the various environments and this is why the NPort IA5150A/IA5250A series provides DIP switches for setting
the pull high/low resistor values for each serial port.
The DIP switches are located on the PCB board; you will need to take off the covers to access them. To set the
pull-high resistor to 150 KΩ, flip DIP1 to “OFF,” and then set the pull-low resistor to 150 KΩ, and then flip DIP2
to “OFF.” To set the pull-high resistor to 1 KΩ, flip DIP1 to “ON,” and then set the pull-low resistor to 1 KΩ, and
then flip DIP2 to “ON.” Make sure that DIP3 is “ON” to enable the 120Ω terminator. The default settings for the
pull-high and pull-low resistors, and the terminators are all at “OFF.”

3. Initial IP Address Configuration
When setting up your NPort IA5150A/IA5250A 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 the NPort
IA5150A/IA5250A’s IP Address. For more details about network settings, see the Network Settings

3-2
Initializing the NPort’s IP Address
Determine whether your NPort IA5150A/IA5250A needs to use a Static IP or Dynamic IP (either DHCP or
BOOTP application).
If the NPort IA5150A/IA5250A is used in a Static IP environment, you can use the NPort
Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the new IP address.
If the NPort IA5150A/IA5250A is used in a Dynamic IP environment, you can use the NPort
Administration Suite, Web Console, Telnet Console, or Serial Console to configure the NPort IA5150A/IA5250A
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 IA5150A/IA5250A
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 IA5150A/IA5250A.
Factory Default IP Address
NPort IA5150A/IA5250A 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 IA5150A/IA5250A 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 IA5150A/IA5250A.
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 IA5150A/IA5250A 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
IA5150A/IA5250A. The ARP command tells your computer to associate the NPort IA5150A/IA5250A’s MAC
address with the intended IP address. You must then use Telnet to access the NPort IA5150A/IA5250A, at
which point the device server’s IP address will be reconfigured.
ATTENTION
In order to use this setup method, both your computer and NPort IA5150A/IA5250A must be
connected to the
same LAN. Or, you may use a cross
-
over Ethernet cable to connect the NPort IA5150A/IA5250A directly to
your c
omputer’s Ethernet card. Before executing the ARP command,
your NPort IA5150A/IA5250A must be
configured with the factory default IP address
(192.168.127.254), and your computer and the NPort
IA5150A/IA5250A
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 IA5150A/IA5250A from your network administrator.
2. Obtain the NPort IA5150A/IA5250A’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:
4. arp –s 192.168.200.100 00-90-E8-xx-xx-xx
5. 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 IA5150A/IA5250A. (Be sure to use the actual IP address and MAC address for your NPort
IA5150A/IA5250A.)
6. 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 IA5150A/IA5250A’s IP address. This can be done using Telnet.

Serial Console (19200, n, 8, 1)
You may use the RS-232 console port to set up the IP address for the NPort IA5150A/IA5250A. We suggest
using PComm Terminal Emulator, which is available free of charge as part of the PComm Lite program suite, to
carry out the installation procedure, although other similar utilities may also be used.
ATTENTION
The
Serial Console is serial port 1 of the NPort IA5250A series and it is the DB9 serial port (in RS-
232 mode)
of the NPort IA5150A series.
Before you start to configure the NPort IA5150A/IA5250A via serial console, turn off the power and connect the
serial cable from the NPort IA5150A/IA5250A to your computer’s serial port.
1. Connect the NPort IA5150A/IA5250A’s serial port 1 directly to your computer’s male RS-232 serial port.
From the Windows desktop click on Start Programs PComm Lite Terminal Emulator.
2. When the PComm Terminal Emulator window opens, first click on the Port Manager menu item and select
Open, or simply click on the Open icon.
3. The Property window opens automatically. From the Communication Parameter page, select the
appropriate COM port for the connection, COM1 in this example, and 19200 for Baud Rate, 8 for Data Bits,
None for Parity, and 1 for Stop Bits.
4. From the Property window’s Terminal page, select ANSI or VT100 for Terminal Type and then click OK.
