CNB SKB-21Z12F - Manual (Page 6)

◎ Termination switch(Pin 6~7) is used in cases listed below.
Termination Switch Setting
◎ Select the appropriate Protocol with DIP switch combination. (Pin 1~3)
Communication Protocol Setup
◎ Long-distance communication between the controller and the camera (1-to-1
connection)
- When the connecting distance between the two units is especially long,
communication errors may occur due to the impedance of transmission cable. In this
Termination Switch is used in case listed below.
NO PROTOCOL BAUDRATE #1 #2 #3
0 SONY 9600bps OFF OFF OFF
1 SONY 38400bps ON OFF OFF
2 PELCO-D 2400bps OFF ON OFF
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.
3 PELCO-D 9600bps ON ON OFF
4 PELCO-D 38400bps OFF OFF ON
5 PELCO-P 4800bps ON OFF ON
6 PELCO-P 9600bps OFF ON ON
Others Reserved
◎ If you want to control using DVR or P/T controller, their protocol must be identical to
camera. Otherwise, you can not control the camera.
◎ If you changed camera protocol by changing DIP S/W, the change will be effective
after you reboot the camera.
