I have a Strand Basic Palette hooked into an NSI IF501 converting DMX to MPX (which goes to our dimmers), and then from the DMX out on the IF501 I have it patched to 6 Coemar ProLed Lite's. We only have 24 Channels of dimming, so i have the Coemar's addressed from channel 30 onwards. However, I am not getting anything on the fixtures. When i plug the DMX into the A port on the board, they work fine, but when i use the DMX passthrough on the IF501 it doesnt work. Our Board has a DMX B output, but the Coemars cannot be addressed higher than 512, and i cannot map the 1st universe to both DMX ports. I need both the LED's and my conventional dimming to work off the same board at the same time, using light jockey or PC control is out of the question... Any Ideas?
