 Terminal Resistor Setup
The terminal resistor is used for the following cases.
z 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.
z
Case 2 : In case that multiple cameras are connec
ted 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. G
