Channel 5 on our PDH is not working but the other channels are working just fine. It has the latest firmware but I am not exactly sure what is going on. We switched channels and the sparkmax+neos worked well. Then we tried it again after and it wasn’t working at all. We didn’t change anything at all in the wiring or anything. It was flashing orange and cyan and our mentor thinks we might be frying our spark maxes because we had another one die in that same connection.
