• If you want to control using DVR or P/T controller, their protocol must be identical to camera.
Otherwise, you cannot control the camera.
• It you changed camera protocol by changing DIP S/W, the change will be effective after you
reboot the camera.
• Factory default of protocol is “Pelco-D, 2400bps”.
■ Input Sensor Active Type
• When a sensor input is used, its functional type should be set.
There are two types; Normal Open type and Normal Close type.
-Normal Open : Voltage is let out when the sensor is activated
-Normal Close : Voltage is let out when the sensor is not activated

• If a wrong type of sensor is selected, it activates in the opposite way to the sensor input.
■ Termination Switch Setting
Termination switch (Pin 4) is used in cases listed below.
• Long-distance communication between the controller and the camera (1-to-1 connection)
When the connection distance between the two units is especially long, communication errors
may occur due to the impedance of transmission cable. In this case, set the termination switch
of both units to ON.
• Controlling multiple cameras (Multiple connection)
The camera may not operate correctly if multiple cameras are connected and controlled. In this
case, set the termination switch of the controller and the last connected camera to ON and the
switch of other cameras is OFF.
Ex) Using the Terminating Resistance.
