My ARTNET/DMX fixture monitor output is black and has a zero value regardless of what color is highlighted on the screen. I am trying to get a supernight rgb led strip to turn red using a redsqure image from modul8. when tested in enttec nmu the sliders for the 3 channels (rgb) all light just fine but I get no response from the led or any output data in the output monitor on madmapper. Please help.
P.S. lighting n00b
