NPort W2150A/W2250A Series Introduction
1-2
Overview
In this chapter we introduce the basic features and specifications of the NPort W2150A/W2250A and NPort
W2150A/W2250A-T, referred to collectively as the NPort W2150A/W2250A Series.
The NPort W2150A/W2250A Series of wireless device servers are used to connect RS-232/422/485 serial
devices such as PLCs, meters, and sensors, to a wired Ethernet LAN or wireless LAN. Your communications
software will be able to access the serial devices from anywhere over a local LAN, WLAN, or the Internet.
Moreover, the WLAN environment offers an excellent solution for applications in which the serial devices are
moved frequently from place to place.
The NPort W2150A/W2250A supports both automatic IP configuration protocols (DHCP, BOOTP) and manual
configuration using a standard web browser. Both IP configuration methods ensure quick and effective
installation. In addition, a utility called “NPort Windows Driver Manager” makes port mapping easy.
The external antenna can be adjusted for maximum signal strength. You can also choose to use your own
antenna for additional flexibility and scalability. A signal strength indicator on the front panel makes it easier for
you to troubleshoot any connection problems.
The NPort W2150A/W2250A Series offers different operation modes to ensure compatibility with standard
network APIs, including TCP Server Mode, TCP Client Mode, and UDP Mode. RealCOM/TTY drivers are provided
to allow legacy serial-based software to communicate over an IP network instantly. This preserves your
software investment while providing all the advantages of networking your serial devices.
For easier management, the NPort W2150A/W2250A include features such as password authentication, IP
filtering, 64-bit and 128-bit WEP encryption, and SNMP support.

setting while in RS-232 mode. Doing so will degrade the RS-
232 signals and reduce the
effective communication distance.

Placement Options
The NPort can be placed on a desktop or other horizontal surface. You can also install the NPort on a DIN-rail
or on the wall.
Wall Mounting DIN-Rail Mounting
Connecting the Hardware
ATTENTION
Before connecting the hardware, follow these important wiring safety precautions:
Disconnect power source
Do not install or wire this unit
or any attached devices with the power connected. Disconnect the power before
installation by removing the power cord before installing and/or wiring your unit.
Follow maximum current ratings
Calculate the maximum possible current in each power wire and c
ommon 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.
Use caution
- unit may get hot
The unit
will generate heat during operation, and the casing may feel hot to the touch. Take care when handling
unit. Be sure to leave adequate space for ventilation.
The following guidelines will help ensure trouble-free signal communication with the NPort.
•Use separate paths to route wiring for power and devices to avoid interference. Do not run signal or
communication wiring and power wiring in the same wire conduit. The rule of thumb is that wiring that
shares similar electrical characteristics can be bundled together.
•If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the
intersection point.
•Keep input wiring and output wiring separate.
•Label all wiring to each device in the system for easier testing and troubleshooting

Connecting to the Network
Use the supplied Ethernet cable to connect the NPort to your Ethernet network. If the cable is properly
connected, the NPort will indicate a valid connection to the Ethernet as follows:
•A green Ethernet LED indicates a valid connection to a 100 Mbps Ethernet network.
•An orange Ethernet LED indicates a valid connection to a 10 Mbps Ethernet network.
•A flashing Ethernet LED indicates that Ethernet packets are being transmitted or received.
Connecting the Power
Connect the VDC power line (12 to 48 V) to the NPort’s power jack or terminal block. If power is properly
connected, the “Ready” LED will initially glow red. When the system is ready, the “Ready” LED will turn green.
Connecting to a Serial Device
Use a serial cable to connect your serial device to a serial port on the NPort.

NPort W2150A/W2250A Series Initial IP Configuration
3-2
Overview
This chapter presents several ways to assign the NPort’s IP address for the first time. Please refer to Chapter
2 for instructions on connecting to the network.
The web console is the recommended method for configuring the NPort. Please refer to Chapter 5 and 6 for
details on using the web console for configuration.
ATTENTION
The LAN and WLAN interfaces cannot be used at the same time. If the Ethernet link is active, then WLAN
connections will be disabled. If the WLAN connec
tion is active, then the Ethernet link will be disabled.
ATTENTION
Make sure that the Ethernet cable is connected before powering up the NPort.
Factory Default IP Settings
Network Interface IP Configuration IP Address Netmask
LAN Static 192.168.126.254 255.255.255.0
WLAN Static 192.168.127.254 255.255.255.0
If your NPort is configured to obtain its IP settings from a DHCP or BOOTP server but is unable to get a response,
it will use the factory default IP address and netmask.
ATTENTION
If you forget the IP address of your NPort, you can look it up using the NPort Search Utility. After NPort Search
Utility has found all NPorts on the network, each unit will be listed with its IP address. Please refer to Chapter
11 for additional information on using NPort Search Utility.
Using ARP to Assign IP Address
The ARP (Address Resolution Protocol) command can be used to assign an IP address to the NPort. The ARP
command tells your computer to associate the NPort’s MAC address with the specified IP address. You must
then use Telnet to access the NPort, at which point the device server’s IP address will be reconfigured. This
method only works when the NPort is configured with default IP settings.
1. Select a valid IP address for your NPort. Consult with your network administrator if necessary.
2. Obtain the NPort’s MAC address from the label on its bottom panel.
