RS485 CONNECTION

It's possible to control an external device by the DVR using the RS485 interface for communication.

The RS485 port can be used to control PTZ cameras, speed domes, keyboard controllers and other types of external

devices.

Connect the RX+/TX+ & RX-/TX- of the external device to the + & - of the RS485 port respectively.

It’s not possible to connect a PTZ device and a keypad device (SSC-2000) to the RS485 port and use the two

devices at the same time. In order to use a PTZ device with a keypad or another type of external device, you

will need to install a separate COM port expansion card.
