DMX flickering problem. Using Show Express. All fixtures work ok except these 2 old American DJ - DJ Scan 250s keep jumping around like the DMX signal has noise in it. I have replace the cables.
Did you ever resolve this? I've got some new nice lights that are now flashing too. And I have some cheap lights in the chain, so I don't know if the cheap lights are affecting the higher end lights due to the cable. now I did have mic cables, but they worked for months with no problem.
While the comment of DMX termination is completely appropriate as a place to start, I would suspect something more on a component failure/degradation level. Old fixtures with halogen lamps have been baked pretty hard after several years of use. It would take thorough servicing and fixture diagnostic to be sure what's going on, but I suspect it would be time to replace components on the PCB's along with a general work over. Most people would replace fixtures by that point.
I have tha same problem with someold scanners. Works fine in standalone or i 4 unit show. Works fine with my old dmx controller. But when i plug it in in my airstream dmx brige or show express dongle it flickers like on your video. What do i do too fix it?
I never did fix it. I ended up getting rid of those fixtures. New DMX lines. Terminators on the end. Single DMX line to one single fixture. Nothing worked.
@@Globerson Oh yes they can. The majority of DJ fixtures (cheap) simply pass the DMX straight thru and completely unbuffered. As a result they are subject to data line noise and ringing. Always, ALWAYS, terminate the end of the line.
