So today I finally plugged in my Dumb RGB strip into my new Ray Wu 27ch board and both work in test mode. Then I connected that to my D2 (powered by a 5v plug pack) and the 2 lights on the board come to life. Plug in my Cat6 cables and I see the input on the D2 are flashing as I adjust RGB faders on the laptop. However no lights are on the RJ45 for either Universe 1 or 2 (no matter which side I plug into) Therefore, no signal seems to be getting to the 27ch board and therefore no lights Please help, has anyone else experienced this or do I have a dodgy/faulty board? Any other tests to run to check where issue may lie?
