 Terminal Resistor Setup

The terminal resistor is used for the following cases.

Case 1 : In case that the control cable length between a
camera and a controller is relatively very long (1:1
Connection)
If the communication cable length is very long, the electrical
signal will bound in the terminal point. This reflected signal
causes distortion of original signal. Accordingly, the camera can
be out of control. In this case, the terminal resistor of both sides
i.e. the camera and the controller must be set to ‘ON’ state.

Case 2 : In case that multiple cameras are connected to a
controller.
Due to similar reasons with the case 1, the terminal resister of
the controller and the last camera must be set to ‘ON’ state. The
last camera means the camera farthest in cable length from the
controller. Do not turn on the terminal resistor of all the
cameras on the same communication cable.
