I upgraded my I/O card to enable RDM recently. I can't pin it down, but I think it's causing signal problems. For instance: I had about 40 Kino Image 87s in a rig. They were all responding very slowly to commands. Everything else in the rig responded normally. When, finally, I changed my DMX signal rate to "slow" in the shell, the Kinos responded normally again, although they still displayed a blinking "dmx signal" light. (meaning they didn't have good DMX. However, we checked the signal going into the chain of Image 87s, which was good.)
More recently, I was doing a camera test, with just 1 VL3000, and a bunch of Chroma Q color blasts. The color blasts were responding great, and all the non intensity perimeters of the VL3000. However, the intensity parameter was having the same delay as the Kino Image 87s. I never actually tried switching the DMX signal rate to "slow" on that occasion, because it wasn't critical.
Today, I'm on a small stage with existing LED Spaceflights (unknown manufacturer). I've taken control of those house spaceflights in conjunction with our installed conventional dimmer racks. I'm regularly turing the spaceflights on and off for a cue. Pretty much every time i turn them back on, they start flickering to some degree. However, if i turn them off and on a time or two, they're fine....until I turn them off again. I'm going to try the slower DMX rate at lunch, when I can go to the shell.
Anyone else with these sorts of ghosts in the machine after upgrading the I/O board firmware?
