Installation When the resistance value of copper wire is at [20°C(68°F)] Copper wire size (AWG) #24(0.22mm2) #22(0.33mm2) #20(0.52mm2) Resistance (Ω/m) 0.078 0.050 0.030 Voltage Drop (V/m) 0.028 0.018 0.011 #18(0.83mm2) 0.018 0.006 • As shown in the table above, voltage decreases as the wire gets longer. Therefore use of an excessively long adaptor output line for connection to the camera may affect the performance of the camera.  Standard voltage for camera operation : DC 12V±10%, AC 24V±10%  There may be some deviation in voltage drop depending on the type of wire and the manufacturer. Notes • Be sure to connect power only after all the installation is complete. • Note that AC / DC adaptor is not supplied with camera. • Ground should be connected to the GND terminal. Control via RS-485 Interface The camera can be controlled by using external controllers like a Remote controller. (RS-485 Communication) (1) To control by PC C onnect the RS-485 control port of the camera and the serial cable through an RS-485 converter. Example) P C Serial Port (COM1) → Serial Cable → RS-485 Converter → Camera RS-485Control Port. (2) To control using a DVR or System Controller Connect the RS-485 cable (TRX+, TRX-) to the connection port of the 485 control board that is connected to the DVR or System Controller. 485 Control Board Connection Port (+) CONNECTION TERMINAL (TRX+) (- ) CONNECTION TERMINAL (TRX-) RS-485 Control Port 485+ 485- COLOR CCD CAMERA 18 User Guide * RS-485 Communication establishment initial value Item Camera ID BAUD RATE UART MODE Initial value 1 9600 8-NONE-1 RET PKT ENABLE Notes • T o control the camera by constructing an additional controller, use the SAMSUNG-T, SAMSUNG-E, PELCO-D, PELCO-P, BOSCH, HONEYWELL, VICON and PANASONIC protocol.
