I have a few of the Ray's 27 channel DMX RGB controllers. One works great, but two others are causing me pains. When running in 'Fun' mode, each channel lights up. However, I cannot control each channel individually. That is, using LSP or other DMX controlling software via the J1SYS ECG-DMXREN8, I can only get the channels to respond when I turn everything on. If I try to control channels individually, they may respond, but often times, they do not. Watching the DMX activity light, it has DMX input, then goes solid for 2-3 seconds like there is no DMX activity, even though I am outputting DMX. The other controller I have does not behave this way. Is there a firmware update or some other trick? I have the 2 faulty ones configured the same as the one that works, except on a different universe. I tried switching the universes around so the faulty ones were on the 'working' universe, but the problem followed the controllers.
