The terminal resistor is used for the following cases.
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.
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.

DO NOT CONFIGURE! This configuration is to upgrade its firmware
by the manufacturer only.
It must be always set to ON.
