Good idea. I don't think the controls had been touched in at least 10 years . Thanks.

I have a DS8-12 that has the "intermittent bump button" problem where there are false bump signals which cause the lights on some channels to go to 25%. From what I've read this is caused by the switches failing due to age. The bump buttons were set to latch mode and the channels with the...

In case anyone is interested, I have most of the bugs out of the system. The primary problem was in the IF501 -- the unit uses insulation displacement connectors to hook the DMX connectors to the circuit board, and one of the wires (signal common) wasn't making proper contact. Easy to find...

Glad it's working. Electrical design is my day job.Five days ago I was trying to survive having 4 grandkids under 9 in my house for several days. That, and trying to get an NSI IF501 to talk to a CD80.Martin

Sharyn, So far I've worked out the interface problems between the 808CP and the IF501 -- works fine if I remove the termination jumper on the 808CP. That much I could do at home. The rest will have to wait a few days. The IF501 sits on the dimmer. The console (actually laptop with USB to...

Thanks for the quick reply. It looked like a timing issue to me, but I don't have the AMX192 spec, and I don't think I have time to order the spec from USITT with the program 2 weeks away. That leaves me with re-building cables and having another set of eyes look at the jumpers as the...

My church has an older CD80 pack (AMX only) and Mantrix board. For our Christmas program I'm trying to set up to run off a laptop so I can do a cue list instead of running manually. We've bought an NSI IF501 and an Enttec Open DMX USB unit. We also bought an NSI 808CP to use as a day-to-day...
