Terminal resistor is used if your system meets one of following two
conditional cases.
Case1: Control cable between camera and controller is
relatively long (1:1 connection)
If communication cable is very long, the electrical signal will bind in
the terminal point. This reflected signal causes signal distortion,
resulting in a degradation of camera function. In this case, the
terminal resistor of both sides (i.e. camera and controller) must be
set to the 'ON' state.
Case2: Multiple cameras are controlled at the same time
Due to similar reasons stated in case 1, the terminal resisters of the
controller and the last camera must be set to 'ON' state.
camera with the longest cable length is determined to be the 'last'
camera. Do not turn on the terminal resistor of all cameras.
