• How to Connect to RS-485
• Connecting the Video Output
• Connecting the Alarms
The EasyTrak™ PTZ dome camera has built-in RS-485 receiver so that it can be
controlled remotely by an external control device such as a Controller Keyboard or
a DVR.
RS-485: Connect the TXA (Tx+) and TXB (Tx-) of the RS-485 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.
