I got an RX2700 lightbar the other day. It has the 12v power wires and a telephone jack looking serial cable but no controller. I found the manual online that has part numbers for two or three controllers which I think includes the boards inside the bar. Do any of you know which controller I need and a part number? Better yet does anyone have a controller for sale? This has what I think is multi-color LEDS. It also has LED takedowns and alley lights on the feet. Thanks all!
