My school is running a Lehigh Millenium dimmer board, using DMX 512 wiring. We have multiple juniors and borders, and a few 6" Shakespeare Ellipsoidals. I HAVE checked the Channel <> Dimmer mapping options and setup, so don't say that that is the problem. Dimmer 52 doesn't work. Channel 52 is patched to Dimmer 52, and that is it. Raising 52 to 100% does nothing. 52 will occasionally flash "01" or "02". Here's the freaky thing: Whenever I raise Channel 51 to 100% (nothing mapped but Dimmer 51), 52 goes to 98%/99% and parks. I'm thinking short circuit or tripped breaker. Any Suggestions?
