Hello everyone! Long time lurker first time posting. I just took over a new theatre as TD and ran into a very odd problem with their DMX control system and was wondering if someone could help. The problem is that when you plug the console (Expression 3) into any of the DMX input ports in the theatre. All the lights go crazy flickering and flashing at random. BUT when you run into any of the ports by first running the DMX through a DMX splitter we don't have that problem. I remember running into this problem once before years ago and I seem to remember that the solution is pretty simple but I can't for the life of me remember what the solution was. Any suggestions? Thanks!
