First of all we suggest to check that all connections and cables are properly set. Please ensure that main power supply and Moxa NPort adapters are connected to an active power source.
Verify that Moxa NPort adapter “Ready” light is active (red or green, not relevant). If this is not happening and you are sure that the power socket has an active power line, please ensure that the feed-in cable is not only inserted in the feed-in connector but also properly screwed in.
If Moxa NPort adapter is showing “Ready” and “Link” diodes in a red state, this means that connection is not properly set. Verify that the Ethernet cables are properly plugged into the Moxa NPort and the router as well as the entire daisy chain cables are properly fitted into their panel connectors. Ensure that all the ferrules are properly tighten and DSUB connector on Moxa NPort is properly screwed in.
If, after checking that communication and power line is properly done, you are still unable to control the fixture, read carefully the Control Software User manual to ensure that you have followed all the proper passages and to verify if the software is able to communicate with the hardware (Log/Configuration sections may help to troubleshoot further).
