I have one of these cheap lighting desks, a few years old now:
Lastnight when I powered up my garden lights, all the lights flickered (like they were getting bogus DMX data). Today I get nothing. I have plugged a moving head unit directly into the desk, it doesn't recognise the DMX signal. As a sanity check I plugged my garden DMX universe into my USB dongle, and ran the Vixen show. Everything is good. Equally I can also control the lights with Q light controller which is a software lighting desk.
So.... there's something funny about the DMX data coming from the desk. I've checked it in a 2 channel oscilloscope, everything looks very normal (the differential transceiver is doing what it should). The DMX framing and timing looks correct. Each bit of data is 4ms, I see the bits changing correctly when I adjust channel values.
I am totally out of ideas, other than toss it in the trash and buy another one.
Anyone?
Thanks!
