The most common reason Transmitters or Receivers lose communication is network issues. Follow these steps to diagnose and repair
If the unit can be discovered, but you cannot give it any commands, you probably have an incompatible IP address. Discovering is a broadcast that can potentially cross subnets while issuing a command is direct communication. For example…
This DVR was just discovered and is red:

This means broadcast packets got through, but direct communication did not.
Going to its settings page, we find its IP address is 172.10.10.224:

Now go to your DiVAS or Conductor Server’s IP Settings:

You’ll see that it does not have an IP assigned that can communicate with the DVR. Change the 2nd IP to one that is compatible with the DVR (such as 172.10.10.100). Then you can assign a DVR a correct IP address. When finished, change DiVAS or Conductor Server’s 2nd IP back.
If you are using Conductor NetLite, you would change the IP using your normal Windows IP configuration to communicate with the unit.
