erminal resistor is used if your system is one of following two cases.
Case1: Control cable between camera and controller is relatively
very long (1:1 connection)
If communication cable is very long, the electrical signal will bound
in the terminal point. This reflected signal cause distortion of
original signal. Accordingly, the camera can be out of control. In
this case, the terminal resistor of both sides i.e. camera and
controller must be set to ‘ON’ state.
Case2: Multiple cameras are controlled at the same time
Due to similar reasons with case 1, the terminal resisters of
controller and the last camera must be set to ‘ON’ state. Last
camera means decided by cable length. Do not turn on the terminal
resistor of all cameras.
