I have 3 RGB spot lights, that I was using with Vixen, but I can not get them to work with Xlights. I am using the DMX effect with only 3 channels. If I go into the test lights and turn on the output I get the Rx Dmx light to light on the dongle and they work fine. But they do not come on when I program them to come on in the sequence? I guess, I need to add something or do something. Is there any information on this?
