Disregard this post - I reloaded 2.7 and all seems fine.
I had DMX working on a test v1 F8-B, but now I've got a new F8-PB running v2.7, I cannot get DMX to work on any of my F8 boards.
Set BBB tab at 8 serial output
Start address as 1
Port (13-16) pin 1&2
As pixel ports they are working.
I thinking the test button didn't work, be ending to be a test sequence. (Yes/no)
Assume my Vixen 3, Open DMX sequence is correct.
Any suggestions, comments or check points?
