yes the jumpers set up for DMX use and I was using channel 1,2,3,4. As I was looking at it more last night, I found one of the four channels working. Apparently the tracs had been removed and replaced and the solder pads were damaged. Handling the board I bent or moved the trac and it lost contact. after making a few jumpers I got the board working and it is operating properly now. Thank you for the assistance.
