■ 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.
