Reanrd Output issues
« on: October 17, 2016, 05:55:09 PM »
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).


Config attached

Ok, broken channels was resolved by a power cycle of the renard board, which is weird.


But I'm still getting dropped frames, so fades get stuck, etc. Any idea why the signal from the F4V2 3' away is poor but a e1.31 bridge 20 feet away is fine?

It turns out the RS485 line driver IC on my F4V2 was weak. I replace the chip with another 485 line driver and it works fine now, with jumpers in place.

Glad you got it working. PM me your address and I can get you another driver out in the mail.
