Can't connect Sony PDW-F335 XDCAM to ATEM Television Studio

Hi guys!
I'm having problems connecting my Sony PDW-F335 camera to my ATEM Television Studio.
I'm using the BNC cable (double checked, cable if fine) to SDI slot on my ATEM. The resolutions match, all the settings are ok, but I’m still getting black screen on the preview. I can see the HDMI laptops, other camera connected to SDI slot, but Sony PDW-F335 camera NO. I can’t work out why. Please help. Thx.

Make sure you are connected to the lower BNC connector on the camera back,
below the battery, not the side analog video out.

Check your menu setting for HD signal not down-converted SD.

Make sure "ANA V OUT SAVE" is set to OFF on the Cam Config page Maintenance menu.
