I operate a S900 and have recently purchased a Z15 GH13.  After setting it up and testing it, I found that when I triggered the shutter release, I lose the video downlink completely.

I can trigger the shutter on the camera with no problems, its when I do it remotely.

The GREEN LED shows that the camera and gimbal are connected, however after the shutter release, it flashes red.  I can still trigger the shutter, however the downlink is lost.

The HDMI-AV board is V4 and all firmware updates are up to date (including the GH3).

Does anyting have a solution for this?  I'm considering replacing the HDMI-AV board to see if it has any effect.

Thanks,
Jon

Hi , the GCU version should be 2.4, IMU 1.18, gimbal assistant s/w version should be  1.4, please check if these are updated to the latest
