I have 2 LEs, one channel 1-16, the other 17-32... tested them and work just fine when hard wired to dongle. (YEAH!!)
Took out the RS485 chip on the first LE, inserted the RX. Disconnected DMX IN cable from LE and hooked up to TX. First LE works just like it did with wires (YEAH #2).
But the 2nd LE isn't doing anything, and doesn't appear to be getting DMX signal (Boo). I am not sure if the first one isn't sending the signal or the 2nd one isn't receiving it, or if I am just missing something like pulling the RS485 chip on the 2nd board. Just don't want to go pulling chips and risking damaging them if it is something simple, like a jumper. Which reminds me, these are both v3.0 boards. I don't think it is that because both worked fine wired, but you experts may know better.
