Here is an interesting one. So, for the first time in 2 weeks of operation of the rig for the current show I started to have a wacky DMX issue. All of the DMX gear on one of my electrics just started to twitch. The electric is fed from one DMX line from an Opto-Splitter. There are two ETC Revolutions, an ICue on a SmartPower PSU, and 4 Chroma-Q Mk.II Scrollers on a Chroma-Q PSU. The chain goes: Opto>SmartPower (ICue)>Chroma-Q PSU>Rev>Rev. I didn't put a terminator in the last Rev as I have the ones with built in termination. The odd thing is that the "twitch" only shows up after everything is powered up for a while. Also, it goes away when I hard reset the Chroma-Q PSU. However, I noticed that when I powered down the PSU the "twitch" got worse until I powered it back up. More odd things. So last night, as I said, we had the same issue. I did a hard reset on the gear and it all worked fine for the show, we never saw the "twitch" again. So far today, after a reset it all seems to be working fine. I do a channel check before every show, and everything has always been working fine at channel check. After Channel Check, before the stage warmer, we have a cue for fight call, but we haven't noticed the twitch until we get into the stage warmer cue (though no one has been paying much attention to the lights during fight call). I don't know if I will have much time to troubleshoot today as it is a double header day and the show is 3 hours long. I probably won't be able to work on it in earnest until Monday. If you have any thoughts, let me know.
