Apologies for resurrecting an old thread but I am tearing my hair out trying to get our ATEM Television Studio HD Pro to function as a PTZ controller for a Sony BRC-H700 via the DB9 socket on the ATEM.
VISCA is enabled, the camera and ATEM are both set to 9600 baud rate and the camera is set for auto addressing - but nothing.
I've following the pin-out per the current BM PTZ control manual (dated April 2018 - I'll try to attach a snip) which is different both to the previous version and to the version which Daniel posted earlier on in this thread. So I am about as confused as I ever hope to be...
Before I stab myself in the eye with the soldering iron, could someone confirm the correct pin-out for me?
Many thanks!
