COM port
1 x COM (RS-232) data port for codec control and
configuration through API commands.
Camera Control port
1 x Camera Control (RS-232) port for power and
camera control (pan, tilt, zoom) using the VISCA™*
protocol.
Main connector. The main camera is connected
to the Camera Control port.
Power. Pin No. 4 on the Camera Control port
provides 12 V DC / 1 A to the main camera.
If more than one camera is connected, only the first
camera is powered from the codec. The additional
cameras must be daisy chained by using a serial
cable and external power.
