I'm not able to get the DJI Transmission system to work with my FX6 whne using SDI to connect the transmitter to the camera. I have the SDI output set to 1080P and I've tried it at both Level A and Level B, but the transmitter never recognizes the video signal (I get the red indicator light and the no-video source icon on the screen).

HDMI works fine with the same output settings. I've also tried several SDI cables, so confident it isn't a cable issue.

I could be wrong, but I SWEAR this was working before the 4.0 firmware was released for the FX6. Does anyone else have SDI working?

Hi there, did you get it running. Facing the same problem here.

Yes, I had to set the FX6 to output at 1080P, then it worked fine.
