Hello everyone, This year will be my first year using controllers and everything so far has been going smoothly in my planning and testing. I have all my smart pixels wired and tested. However when it comes to the dumb pixels etc. I am having a few problems. I have recently purchased 4 2nd hand 27ch controller boards (ray wu) and they were all working a few months ago using my own pixlite long range as a dmx converter/bridge. Now when it comes to setting everything up again, I am having a few issues 2 are working perfectly fine and the dmx/power light is blinking away as it should, the other 2 one the led is just solid on and the other stays solid unless I remove the dmx plug which it blinks normally for a few seconds then goes solid again. I have tried swapping the dip swicthes around to see if they are the problem. The 4 boards are currently all daisy chained so the data is getting through as the others are working. Any help would be appreciated.
