No pictures in my gopro

[tlovoll]

Hello! I have a phantom 2 with zenmuse gimbal.
I have connected to a transmitter Fatshark.
I have 3 gopro camera and mini iosd.
I bought plug and paly cable. I can't get any picture in my fatshark glasses from my gopro.
I know I have the correct channel at Fatshark glasses.
I get picture with Fatshark camera, but not with gopro camera.
Do you have any tips on what I'm doing wrong?
I get a picture in my glasses of the IOSD mini info.
Do I have to setup my gopro correct?

No answer, just curious. How do you have everything set up so you can switch back and forth between different cameras?

Thanks,
