i am having a issue with my Hansen Electronics HE123, I'm running a HE123-TX on the left side of the board to run to my HE123 RX Differential Receiver, i am only using 1 port on the Tx and anything plugged into the Receiver at the other end is not lighting up. using a multimeter it does seem that im getting some data down the RJ45 cat 6 cable but still not getting any lights. from what i can see its a programming issue more than likely a setting or something that i have missed in Xlighs / Fpp. Any thoughts on what i could try?
