I have 2 dp-415 originally set up with a stage setter 8 I believe. (not by me) The stage setter was stolen and replaced with adj dmx programmable operator. No problems until a had a bad can that i took down and worked on, when I replaced it I thought I would rearrange plugs, not a good idea I guess, as only 2 can worked. So I put the plugs back in the original positions, and now only 1 can works off the controller. Dont know much about the dmx system, is there some resetting or programming or something I need to do to get it back working?
