Thanks, Ed.
I've tried a couple of fixture profiles . . . 3Ch (RGB), 4Ch (RGB-D), (D-RGB), with no joy.
I was doing this at home, where I only had 3-pin DMX cables available, hence using the 2nd DMX output.
I have a 1-universe desk, so was expecting identical behaviour from each DMX output.
However, when trying the set up at the theatre, with the 5 pin cable from DMX Output 1, my LED strip behaved properly ! All is well !
So I now wonder if there is a problem with my DMX Output 2. Is it "switched off" ?
So for now, my LED Tape problem is solved, but I now need to do some more specific testing on the 2nd DMX output of the desk. This is the 1st time I've used this output since I bought the desk a few months ago.
thanks, Zulu
