Factory default of protocol is “Pelco-D, 2400 bps”.
7.1.3. 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 connecting 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.
