Hi. We have a show tomorrow night and - wouldn't you know it - our lights will not work! Full show programmed and...nothing! Here's what I know: 1. I can activate the dimmers manually (the button on the dimmers), so that's not the issue. 2. I can control the dimmers via MPX via our old board. But, I can't control them via DMX via the old board. That led me to believe it was a problem with the DMX cable (which I only have 1 5-pin cable, so can't test this). BUT 3. I have moving lights connected to outputs 2 and 3 as well and neither of them are working. Is there some reason all of the Expression 3 (800) outputs would have quit working? Any help would be greatly appreciated.
