I'm having the hardest time with Renard ouput on the F4V2. I have a SS8 that behaves fine with an e1.31 bridge. All outputs work as expected. When I move it to the F4V2, (making the DMX to Renard cable) it has signal issues, only responding to random packets. If i remove JP1 on the SS8 (which makes no sense, it's the DB9 Serial ground jumper) response improves maybe only missing every 50th frame, but it isn't perfect. And it's only 4' of cable between the F4V2 and SS8. I've remade the cable from CAT5 twice. Same result. Jumpers on the F4V2 are set to DMX.
In addition, Outputs 1,3-5 don't work. 2 and 6-8 seem to work fine. Even using RGBW test mode on the F4V2, only those 4 outputs work. (remember, this SS8 test fine with a e1.31 bridge, all outputs).
