I'm very suspicious that something deeper is wrong with the V3 implementation. There are lots of LOR boards running with V2 boards, but not a single V3 that I find has been successfully connected to any LOR board.
I just ordered a Son of Chuckie board so I hope to have a backup plan. It says it can operate 16 servos (8 bit, which is all I need). Since Gil has done the heavy work by getting Skulltronix to work, I should be able to jury-rig something from that. But there again, I don't know what Gil was using for a DMX bridge from xLights.
I do have a generic multicast e1.31 to DMX bridge I can use if the Falcon is no go.
I have an LOR dongle somewhere. Perhaps I should try that as well.
