COM port and Camera Control port

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.

Additional cameras. For information about additional cameras, go to the Cameras section later in this guide.
