I have a Fog Fury Jett that we were trying to set up to run on DMX. On initial connection, everything seemed fine. We set channel for D2 (Only want to send color macro value). Upon first run, unit worked when value was sent then sent a 0 value to turn off fog which worked. After that, we lost our connection light and no further DMX commands would work. Checked DMX and everything else is working fine. Swapped cables, no change. It is like the DMX port has quit working. Cycled power as well, still no change. Anybody have any thoughts?
