Hardware Introduction
The NPort W2150A models have one serial port; the NPort W2250A
models have two serial ports. Both models support RS-232/422/485
operation with DB9 connectors and include one 10/100M Ethernet port.

NOTE
Do not use the 1 kΩ setting while in RS-232 mode. Doing so will
degrade the RS
-232 signals and reduce the effective
communication distance.
First-Time Hardware Installation
STEP 1:
After removing the NPort W2150A/W2250A from the box, use
a crossover Ethernet cable to connect the NPort’s RJ45
Ethernet port directly to your computer’s Ethernet port.
STEP 2:
Attach the power adapter to the NPort and then plug the
adapter into an electrical outlet.
STEP 3:
Configure the NPort W2150A/W2250A through the Ethernet
port. See the next section on how to install software.
NOTE
You must connect the Ethernet cable first before powering up
your NPort.
NOTE
The operating temperature of the power adapter in the box is
from 0 to 40°C. If your application is out of this range, please use
a power adapter supplied by UL Listed External Power Supply
(The power output meets SELV and LPS and rated 12
-
48 VDC,
minimum current 0.42 A).
Software Installation Information
For the NPort’s configuration, the default IP address of the NPort is:
LAN: Static; IP = 192.168.126.254; netmask = 255.255.255.0
WLAN: Static; IP = 192.168.127.254; netmask = 255.255.255.0
If the NPort is configured for DHCP, but the DHCP server cannot be found,
then the NPort will use the factory default IP settings.
NOTE
If you have forgotten the NPort's IP address, use the Device
Search Utility
(DSU) from your PC to locate the NPort. After
searching the LAN for NPort units, the DSU will display the IP
address of each unit.
NOTE
Ethernet Bridge Disabled (default):
Only one network
interface can be active
d
at a time. If the Ethernet link is active,
the WLAN will be inactive. If the WLAN is active, the Ethernet link
will be inactive.
Ethernet Bridge Enabled:
The LAN and WLAN will both be
active. Go to the web console, find the network settings page,
and set Ethernet Bridge to Enabled.
You may log in with the account name admin and password moxa to
change any settings to meet your network topology (e.g., IP address) or
serial device (e.g., serial parameters). For first-time use, click the Wizard
in the left navigation panel. The wizard will prompt you to configure the IP
address, SSID, and security mode. For other settings, use the factory
defaults or modify the settings for your application.

For software installation, download the relative utilities from Moxa's
website:
https://www.moxa.com/support/support_home?isSearchShow=1
• Download the NPort Windows Driver Manager and install it as the driver
to run with Real COM mode of the NPort Series.
• Execute NPort Windows Driver Manager; then map the virtual COM
ports on your Windows platform.
• You may refer to the DB9 Male pin assignment section to loop back pin
2 and pin 3 for the RS-232 interface to carry out a self test on the device.
• Use HyperTerminal or a similar program (you may download Moxa's
program, called PComm Lite) to test whether the device is good or not.
