④ COMMUNICATION Setup
(OFF: Upward direction / ON: Downward direction )
Set RS-422, RS-485 or RS-232C by using ON/OFF DIP switch
no.1 and 2.
By using ON/OFF DIP switch no.3(Rx) and 4(Tx), set the terminating resister as shown below.
● For RS-485, use the terminating resister when...
When the distance b/w controller and camera is very far (1:1Connection)
When using multiple cameras at the same time
(1:N Connection)
COMMUNICATION 1 2
RS-422 OFF OFF
RS-485 OFF ON
RS-232C ON OFF
If multiple cameras are connected to one controller at the same time, a
communication failure may occur. In this case, set the terminating resister of the
controller to ON, and set OFF on the camera located ate the very end.
※ DO NOT SET THE TERMINATING RESISTER OFF ON EVERY CAMERA
If the distance between the controller and the camera is very long, a
communication error may occur due to the impedance problem of the
communication line. In this case, set the terminating resister to OFF in both the
controller and the camera.
