I have two controllers. Controller A is connected to the PC running the show via an Ethernet cord. Controller A is connected to Controller B via a phone cord. The LOR software isn't recognizing either controller. I read in the LOR getting started guide that some controllers have selectors that specify whether an Ethernet cable or a phone cable is coming in. Is this true? I don't see any such selector on my controllers. Why else would my software not be recognizing either controller?
