I completed my first Aether, but am unable to set the channel or control the board using DMX. I was successfully able to flash the PIC and everything appears to be working. When I connect the power, all the LEDs flash and the red LED power light stays lit. When I connect the DMX cable from the dongle to the board, the green data light glows. If I disconnect the dongle, the green light goes out. I have tried both DMX ports with the same issue. Any suggestions?
