which the serial devices and Ethernet 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. Real COM/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 includes features such as password authentication, IP
filtering, 64-bit and 128-bit WEP encryption, and SNMP support.

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 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.
Use caution - unit may get hot
The unit will generate heat during operation, and the casing may be too hot to touch. Take care when
handling the 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 (recommended for only
one connection at a time). 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.

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 you don't enable the Ethernet Bridge
mode (please refer to Chapter 7 for more details). If the Ethernet link is active, then WLAN connections will
be disabled. If the WLAN connection 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 Device Search Utility (DSU). After
the Device Search Utility (DSU) 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 the Device Search Utility (DSU).
Using ARP to Assign an 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.
3. From the DOS prompt, execute the arp -s command with the desired IP address and the NPort’s MAC
address, as in the following example:
arp -s 192.168.200.100 00-90-E8-xx-xx-xx
In this example, 192.168.200.100 is the new IP address that will be assigned to the NPort, and 00-90-
E8-xx-xx-xx is the NPort’s MAC address.
4. From the DOS prompt, execute a special Telnet command using port 6000, as in the following example:
telnet 192.168.200.100 6000
In this example, 192.168.200.100 is the new IP address that will be assigned to the NPort.

5. You will see a message indicating that the connection failed.
The NPort will automatically reboot with the new IP address. You can verify that the configuration was
successful by connecting to the new IP address with Telnet, ping, the web console, or the Device Search
Utility (DSU).
Using the Telnet Console to an Assign IP
Address
1. Select Run… from the Windows Start menu.
2. Enter telnet 192.168.126.254 (the NPort’s default IP address) and click [OK].
3. Enter your login account and password, then press ENTER.
(Default login is admin and password is moxa.)

Using the Serial Console to an Assign IP
Address
Before using the NPort’s serial console, turn off the power and use a serial cable to connect the NPort
console port to your computer’s serial port. Port 1 on the NPort serves as the console port. Use Port 1
connecting to the console port with a serial-based terminal or terminal emulator program, such as Windows
HyperTerminal. You may also download PComm Lite at www.moxa.com. The terminal type should be set as
ANSI or VT100, and the serial communication parameters should be set as 19200, 8, N, 1 (19200 for baud
rate, 8 for data bits, None for parity, and 1 for stop bits). As soon as the connection is open, you will be
presented with a text menu displaying the NPort W2150A/W2250A Series general settings. Please refer to
Chapter 4 for a description of the available settings. The following instructions, we recommend using
PComm Terminal Emulator, which can be downloaded free of charge from www.moxa.com, to carry out the
configuration procedure.
1. Connect your PC’s serial port to the NPort’s console port.
2. Open your terminal emulator program, such as Windows HyperTerminal. We recommend using PComm
Terminal Emulator, which can be downloaded for free at www.moxa.com.
3. In your terminal emulator program, configure the communication parameters for the serial port on the
PC. The parameters should be set to 19200 for baud rate, 8for data bits, None for parity, and 1for
stop bits.

4. In your terminal emulator program, set the terminal type to ANSI or VT100. If you select Dumb
Terminal as the terminal type, some of the console functions—especially the “Monitor” function—may
not work properly.
5. Hold the grave accent key (`) down and power up the NPort.
The continuous string of grave accent characters triggers the NPort to switch from data mode to console
mode.
