•
Match the camera protocol with the camera protocol in the setting of your DVR or controller to control the came-
ra.
•
Adjust the DIP switch after turning off the camera. If you changed the camera protocol by changing the DIP S/W,
the change will be effective after you reboot the camera.
• 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.
The complete informations are in the manual on the CDrom.
