My 27 Ch (Ray Wu, holidaycoro..) doesn't seem to be responding to dmx, i read as much as i could find, i know about the test mode on switch 10. I have all switches off except #1 (so dmx address 1) and hooked dmx in to a standard hardware controller ("dmx operator"). I have power to both unplugged while i make the connections. When i power everything up, the LED that i have hooked to the wu controller turns on, but the controller has no effect, the led just stays on at full brightness. The DMX/power light is off, but it seems to stay off whenever i have power going to the led, so i thought that was normal. If i unplug my LED, the DMX/power button blinks at a constant rate. If i then unplug DMX, after about a second it stops blinking, so apparently it's getting DMX. I do have the dmx operator fixture #1 button set on. This controller has ch#1 hardwires to fixture #1, iow, when you have fix #1 selected, you're always broadcasting on ch#1. As i understand anyway, obviously something isn't working.. If i enable test mode (switch #10 on), there's no change, the LED just stays on. Thanks!
