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.

5. First-time Hardware Installation

STEP 1:

After removing the NPort W2150A/W2250A from the box,
use a cross

-over Ethernet cable to connect the NPort’s

RJ45 Ethernet port directly to your computer’s Ethernet
port.

STEP 2:

Attach the power adaptor to the NPort and then plug the
adaptor into an electrical outlet.

STEP 3:

Configure the NPort W2150A/W2250A through the
Ethernet port. See the next section for software
installation in formation.

NOTE

You must connect the Ethernet cable first before powering
up your NPort

6. Software Installation Information

Insert the Document & Software CD into your PC. A window should
open with severa l options displa yed:

• Click [Install COM Driver] an d follow the on-s creen
instructions to install the COM drivers.

• Click [Documents] and select “NPort W2150A/W2250A
Series User’s Manual” to view the user’s manual.

• Click [Install UTILITY] and follo w the on-screen instructions
to install the NP ort Search Utilit y. This utility can be used to
search for NPort W2150A/W2250A units on the network.

7. Setting the IP Address

The factory default IP settings are assigned as follows:

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, the NPort will use factory default IP settings.

NOTE

If you have forgotten the NPort’s IP address, use the NPort
Search Utility from your PC to locate the NPort. Aft

er

searching the LAN for NPort units, the NPort Search Utility
will display the IP address of ea ch unit.

NOTE

Only one network interface can be active at a time. If the
Ethernet link is a ctive, the WLA N will be inactive . If the
WLAN is active, the Ethernet link will be inactive .

Open the web console to make configuration changes as follows:

STEP 1:

Open your web browser.

STEP 2:

In the address bar, enter 192.168.126.254 (the default
IP address).

STEP 3:

The web console will open, and the current configuration
settings are shown.

STEP 4:

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.
