The dome camera has a built-in RS-485 receiver so that it can be controlled
remotely by an external control device such as a joystick controller or a DVR.
RS-485: Connect the TXA (Tx+) and TXB (Tx-) of the RS485 control devices
(KBD, DVR…) to TRX+, TRX- of the dome camera.
RS-485 does not allow for a star connection layout. A splitter is required if a star
connection layout is desired. RS-485 guarantees 1.2 Km of data line routing. A
repeater is recommended to extend over 1.2 Km.
