We have the F16v2 with diff expansion board set up. The red card has had the appropriate update to 1.09 and is happy testing a string of pixels from the S1 position. (this in its self was a victory today). So we got encouraged to run the Cat 5 cable from the Diff Expansion board to the receiver to test a second light string. So after supplying power to the receiver board we anxiously awaited the beautiful color wash to begin on the 2nd string.... but sadly ...only darkness.
After 2 hours of troubleshooting, I'm throwing in the towel. Please help, I feel so close. I've attached pics of the F16v2 with diff exp board and receiver.
