I am checking to see if anyone here has experienced a similar problem with scrollers or perhaps any piece of DMX controlled gear.
I am having a strange recurring problem on a scroller run. It has four scrollers on it, 2 Smart Color and 2 Smart Color Pros. Every so often the scroller that is the last unit in the run (and which has a standard four pin DMX terminating connector on it) will receive a change order from my ETC Element and will then proceed to run wild. It will scroll end to end repeatedly, and nothing short of turning off the light board (which also cuts power to the scrollers) will stop it from doing so. It happened in every show last season, and though I have done extensive trouble shooting I have not been able to prevent the problem from occurring. So far I am blaming the ETC Element, mainly because replacing the unit with another one does not make the problem go away, and it always happens on the same cue in the show. The only thing I have not been able to change is the Element, I don't have a spare one hanging around.
