RS-485 is the interface that communicates to 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 following diagram). Please do not change the default setting without qualified specialists or
a supplier’s notice. The SW3 and SW4 are used for termination and Line Lock adjustment, respectively. To
use the termination, apply the switch to the last PTZ camera as shown in the figure below. Use the SW5 to
restore the camera to the factory default status. Once firmware upgrade is complete, reset the SW6.
