2.7 RS-485
Connector
RS-485 is the interface that the PTZ Camera uses to communicate with its control
unit. Connect the control keyboard to the camera via the terminal block. The
recommended cables for RS-485 communication are
CAT 5
cables; the maximum
cable length for wire with a gauge above 24 is 4000 feet (1219 meters). If the total
cable length exceeds 4000 feet, using a repeater to amplify the signals is
recommended.
