Sorry for the delay in getting back to you. Guitar Center did take the unit back and didn't have one and said I could order it, which I do want to do.
Here's what happened. I plugged the usb dmx box into the laptop. IT was recognized by the laptop. I have approximately 15 lights set up for our CLC at the church that I currently run on a standard 16 channel board. When I unplugged the 3 pin cable from that board and plugged into the dmx it began to smolder. I immediately unplugged it but it was too late.
One other thing, mu cable had a female end on it and I had to use an adapter (male/male) to get it o plug in.
Thanks for your help. Do i need to re-wire?
