RS-485 Connector
The DVR can be controlled remotely by an external device or control system, such as a control keyboard, using RS-485 half-duplex serial communications
signals. The RS-485 connector can also be used to control PTZ (pan, tilt, zoom) cameras. Connect RX-/TX- and RX+/ TX+ of the control system to the TX-/RX-
and TX+/RX+ (respectively) of the DVR. See
Chapter 3 - Configuration
and the PTZ camera or remote controller manufacture’s manual for configuring the
RS-485 connection.
Connecting to the USB Port
USB connector
A USB port on the front panel is provided to connect external hard disk drives, CD-RW drives or flash drives for archiving video. Position the external hard disk
drive close enough to the DVR so that you can make the cable connections, usually less than 6 feet. Use the USB cable provided with the hard disk drive or
CD-RW to connect it to the DVR. See
Chapter 4 - Operation
for archiving video to an external USB-IDE hard disk drive, USB CD-RW drive or USB flash drive.
You also can upgrade the software via USB port.
