I need this too. Apparently people speccing these new Sony PTZ cameras are not reading in the manual the part about 'When IP control card is installed, RS-232 and RS-422 ports cannot be used'... But they want to use a Joystick controller via IP AND RS-232 control via Crestron at the same time. I'm just waiting for the change order to come down at any moment... At which point It'll have to be working yesterday. Many thanks to those who have figured this one out!
