Overview
Moxa’s NPort W2250/2150 wireless device servers are the ideal choice for connecting your
RS-232/422/485 serial devices—such as PLCs, meters, and sensors—to a Wired Ethernet LAN
and 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.
NPort W2250/2150 wireless serial device servers support automatic IP configuration protocols
(DHCP, BOOTP) and manual configuration via a handy web browser console. Both IP
configuration methods ensure quick and effective installation, and the NPort Windows Driver
Manager Utility makes Port Mapping very convenient to configure.
An external antenna increases the range of the wireless connection. Users can position the
adjustable antenna for maximum signal strength or even replace the antenna with their own for
additional flexibility and scalability. This feature is particularly useful when a serial device is
connected in a high interference area. As an added feature, a signal strength indicator is located on
the front panel to make it easier to troubleshoot connection problems.
NPort W2250/2150 wireless serial device servers ensure the compatibility of network software
that uses a standard network API by providing TCP Server Mode, TCP Client Mode, and UDP
Mode. The Real COM/TTY drivers allow software that works with COM/TTY ports to 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.
To make your management task easier, the NPort W2250/2150 Series provides additional features,
such as password authentication, IP filter, WEP support for 64-bit and 128-bit encryption, and
SNMP support.

Connecting the Hardware
This section describes how to connect NPort W2250/2150 to serial devices for first time testing
purposes. We cover Wiring Requirements, Connecting the Power, 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 device.
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!
Be careful when handling the device. When plugged in, the device’s internal components
generate heat, and consequently the casing may feel hot to the touch.
You should also pay attention to the following items:
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.
yUse 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 advisable to label the wiring to all devices in the system.
Connecting to the Network
Connect one end of the Ethernet cable to NPort W2250/2150’s 10/100M Ethernet port and the
other end of the cable to the Ethernet network. If the cable is properly connected, NPort
W2250/2150 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 orange color when connected to a 10 Mbps Ethernet
network.
yThe Ethernet LED will flash when Ethernet packets are being transmitted or received.

NPort W2250/2150 Plus User’s Manual Getting Started
2-4
Connecting the Power
Connect the 12-48 VDC power line with NPort W2250/2150’s power jack. When 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.
Connecting to a Serial Device
Connect the serial data cable between NPort W2250/2150 and the serial device. Serial data cables
are optional accessories for NPort W2250/2150. Refer to Chapter 1 under Optional Accessories in
the Ordering Information section for information about the RJ45-to-DB25 and RJ45-to-DB9
cables.

Factory Default IP Address
NPort W2250/2150 is configured with the following default IP addresses:
LAN:
Setting static IP
IP Address 192.168.126.254
Netmask 255.255.255.0
ÆIf the Ethernet port is unable to get an IP address from the DHCP server, then the IP
address/netmask will revert to 192.168.126.254/255.255.255.0.
WLAN:
Setting static IP
IP Address 192.168.127.254
Netmask 255.255.255.0
ÆIf the WLAN port is unable to get an IP address from the DHCP server, then the IP
address/netmask will revert to 192.168.127.254/255.255.255.0
NOTE If you forget the IP address, you can use the NPort Search utility (from your PC) to locate the
NPort W2250/2150 unit over the network. You will be able to view the IP address on the screen.
ARP
The ARP (Address Resolution Protocol) command can be used to set up an IP address for your
NPort W2250/2150. The ARP command tells your computer to associate the NPort W2250/2150’s
MAC address with the intended IP address. You must then use Telnet to access the NPort
W2250/2150, at which point the device server’s IP address will be reconfigured.
This function only applies to default IP addresses.
Take the following steps to use ARP to configure the IP address:
1. Obtain a valid IP address for your NPort W2250/2150 from your network administrator.
