It appears the problem is with the active hub. I can run all the DMX devices from a USB DMX dongle with no problem. When I tried to reflash the hub that I removed the Pickit software would not recognize the chip so I reheated the PIC socket, the ICSP pins, and the 485 socket between the PIC and the ICSp. Now The pickit recognizes the chip and I can reflash it. Next is to go outside and put this one back in play and remove the backup. Strange that both active hubs failed on DMX out. Unfortunately it is misting out right now and unlikely to get much better today. On the other hand this hub is in a marine battery box and is on the porch so at least under roof. Tonight is a a big Christmas Party so I won;t be home to babysit the show.
