TROUBLESHOOTING
New devices are shipped with the same logical network group
assignment and should have no problems communicating with
each other. If two devices can not communicate, check the
logical network group to make sure they are using the same PLC
configuration utility.
• If the configurations are the same, and the devices fail
to communicate, the electric wiring may be causing the
problem. Examples of potential problems are:
– Old fuse boxes.
– Old wiring that does not meet current wiring building
codes.
• First, make sure the devices are functioning properly. Plug the
units into nearby electric outlets in the same room or into the
same power strip with noise filtering. If the two devices can
communicate, go to long distance debugging steps; if the
two devices still can not communicate, continue to check
the following:
• Check that the Ethernet cables are securely plugged in
• Check the power supply
• Check the LEDs are properly lit, blinking, or turned off
