ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your NPort IA5150A/IA5250A
Wiring
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
alled
with other components, make sure that there is at least 2 cm clearance on all sides of
IA5150A/IA5250A in order to allow proper heat dissipation.

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
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.

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.

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
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.

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

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.

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
Figures in this chapter were generated using NPort
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.
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

4. Choosing the Proper Operation Mode
In this chapter, we describe the NPort IA5150A/IA5250A various Toperation 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.

Overview
NPort IA5150A/IA5250A serial device servers network-enable traditional RS-232/422/485 devices, in which a
Serial 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 the NPort IA5150A/IA5250A serial device servers network-enable
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 IA5150A/IA5250A 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 IA5150A/IA5250A 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 unicast or multicast of data to only one IP or groups of IP addresses.

One of the major conveniences of using Real COM Mode 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 IA5150A/IA5250A 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 IA5150A/IA5250A’s serial ports.
Real COM Mode comes with the NPort IA5150A/IA5250A NPort Administrator.

RFC2217 Mode
RFC2217 mode is similar to Real COM mode in that a driver is used to establish a transparent connection
between a host computer and a serial device by mapping the serial port on the NPort IA5150A/IA5250A to a
local COM port on the host computer. RFC2217 defines general COM port control options based on the Telnet
protocol. Third party drivers supporting RFC2217 are widely available on the Internet and can be used to
implement Virtual COM mapping to your NPort IA5150A/IA5250A serial port(s).

Pair Connection Mode
Pair Connection Mode employs two NPort IA5150A/IA5250A units in tandem, and can be used to remove the
15-meter distance limitation imposed by the RS-232 interface. One NPort IA5150A/IA5250A 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 IA5150A/IA5250A. The two NPort IA5150A/IA5250A
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.
Ethernet Modem Mode
Ethernet Modem Mode is designed for use with legacy operating systems, such as MS-DOS, that do not support
TCP/IP Ethernet. By connecting one of the NPort IA5150A/IA5250A’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.
Reverse Telnet Mode
NPort IA5150A/IA5250A Series Choosing the Proper Operation 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 Reverse Telnet mode.
Disabled Mode
When the Operation Mode for a particular port is set to Disabled, that port will be disabled.
