RS-485 is the interface that communicates the Dome Camera and its control
device; for this reason, the RS-485 setup of the Dome Camera 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 set the camera to the factory default status; moreover, once
firmware upgrade is carried out, users also need to adjust the SW 5 afterward.
