Hi JS,
I downloaded the DMX DECK Software and ran the test. I assume there are no settings required other than selecting the correct com port and selecting the channels you want to test?
I ran the test for board 1 and at first nothing happened, no lights, then I switched USB cables and one of the mini lights came on and the other leds that I had turned on came on also. I then switched back to the original cable, and the lights DID NOT go off. The cable was unplugged and the lights were on!
I turned the power off to the board then on and ran the test again, switched the cables again and no lights no leds. Nothing.
I must admit I'm gonna have a greater appreciation of a working system once it's up and running. This troubleshooting is getting a weeeeee bit old.
Thanks for your help guys. I refuse to be defeated!
