RS-485 is the interface that communicates the dome camera and its control
device; for this reason, the RS-485 setup of the dome and the control device
must be the same. The RS-485 default setting is half-duplex (see the diagram
follows). Please do not change the default setting without qualified specialist
or supplier’s notice. As for the SW 3 and SW 4, they are used for termination
and Line Lock adjustment respectively. The SW 5 is mainly used when users
want to restore the camera to the factory default status; moreover, once
firmware upgrade is carried out, users need to reset the SW 6 afterward.
