ATEM Televison Studio Pro HD and Canon Cameras

My canon c100 Mark 2 camera shows up fine on my new ATEM TSP HD switch. Just bought a Canon C200 and it will not show up. Cameras are on the same settings. When i hook the C200 up to my Video Assist 4K, the signal shows up fine.

help.

How are they connected? The C100 does not have SDI.. HDMI only..

But the C200 can output 4K Hdmi.. So what resolution did the VA4k tell you the camera was on?
