    In most situations the + and - DMX will work sufficiently without the ground. But sometimes the ground is needed if there is flickering of the signal due to ground loops, but in my experience I have just used the DMX + and - only for these boards

    Thanks, That is how I hooked them for testing and it worked, but I didn't want to wire up dozens of lights in the shed over winter, only to find I have a problem when it comes time to set them up at xmas.

    I would like to add my own dumb question to this, how do I get signal to it? I use the J1SYS DR4, but this board does not support cat5/6?

    you need to wire a cable to go from one of the outputs on the dr4 to the 3 pin xlr skt on the 27ch board. from there you daisy chain them using the 4 pin plugs and wires that I was asking about
    The pinouts can be found here...
