Control Via Rs-485 Interface - Samsung SCB-5003 User Manual

When the resistance value of copper wire is at [20°C(68°F)]
Copper wire size (AWG)
Resistance value(Ω/m)
Voltage Drop (V/m)
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.

Be sure to connect power only after all the installation is complete.

The camera can be controlled by using external controllers like a Remote controller. (RS-485
Communication)
(1) To control by PC
Connect the RS-485 control port of the camera and the serial cable through an RS-485
converter.
Example) PC 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.
