		The recommended cable diameter is AWG 28-16 (0.08-1.5 mm2).
		To communicate with the controllable camera, select a port number that is the same as the
		input number to which the camera is connected (for example, configure a controllable camera
		to port 16 if it is connected to channel 16).
4.12	Biphase port
		Use the Biphase port for connecting controllable Biphase-compatible cameras. Five Biphase
		outputs are provided for dome cameras and pan, tilt, and zoom control. The screw terminal

connection board supplied with the unit simplifies all Biphase connections to the unit and protects the port against transient over-voltage.
