2.4 Setting Dome Camera Termination
The device which is connected at end of line, whether it is a dome camera or keyboard controller,
must have the cable for communication terminated by setting the appropriate DIP switch.
Without proper termination, there is potential for control signal errors. Total length of the cable for
communication should not exceed 4000ft (1.2km).

2.5 Setting Dome Camera Address (ID)
To prevent damage, each dome camera must have a unique address (ID).
When installing multiple dome cameras using a multiplexer, it is suggested that the dome camera
address match the multiplexer port number.
The factory default setting is 1.
Refer to Figure 4.1 ~ 4.6 for setting the dome camera address (ID).
