NL240 Wireless Network Link Interface
3. Power cycle the NL240 and your WAP/hub/router/PC.
•
Turn off or unplug your WAP/hub/router/PC and NL240. Wait 10
seconds and then plug them back in or turn them on. A full restart
may take 30 to 60 seconds.
4. Check the settings of the NL240.
• Make sure you have entered the correct SSID and Key/Passphrase (if
needed) for your network.
•
Make sure the NL240 is connected to the right WLAN (Wi-Fi Status
in
DevConfig
or show | Wi-Fi settings | Wi-Fi in a Telnet session).
• Make sure the Wireless Network you are connecting to has a RSSI
level of greater than (>) –90dBm (in DevConfig under the Settings
Editor tab | Wireless Networks in Area list).
• Make sure the assigned NL240 IP address (DHCP or static) and the IP
address of the PC you are trying to connect from are able to
communicate with each other. (Your network administrator can help
you with this.)
For example, the following addresses are able to communicate:
NL240: IP address: 192.168.0.2, Network Mask: 255.255.255.0
PC: IP address: 192.168.0.3, Network Mask: 255.255.255.0
•
If you are using DHCP to assign an IP address to the NL240, use
DevConfig
to read the IP address assigned to your NL240. This is
done through a USB connection to the NL240 while the NL240 is
connected to your network (if bridge mode is not being used).
•
The IP address assigned to the NL240 must be unique on your
network.
• When Bridge Mode is enabled, the datalogger controls how the IP
address is assigned. Make sure your datalogger is connected correctly
to the NL240 via the CS I/O port and SC12 cable.
• Try to ping the NL240 from your PC. (From the Windows Start
Menu, choose Accessories | Command Prompt. Then type ping
xxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx is the IP address of your
NL240.) If no packets are returned, this indicates that there is no
network connection to that IP address.
5. Make sure the IP address and port number entered in
LoggerNet / PC400 / RTDAQ match the settings in the NL240.

Note that PakBus® and serial server communications use different
port numbers. The default port number for PakBus communications
is 6785. The default port number for CS I/O serial server
communications is 6783. The default port number for RS-232 serial
sever communications is 6784. The correct port number must follow
