Network Port

The DVR can be networked using the 10/100Mb Ethernet connector. Connect a Cat5 cable with an
RJ-45 jack to the DVR connector. The DVR can be networked with a computer for remote monitoring,
searching, configuration and software upgrades. See the Network Setup section in this chapter for
configuring the Ethernet connections.
CAUTION: The network connector is not designed to be connected directly with cable or wire
intended for outdoor use.

Factory Reset

CAUTION: When using the Factory Reset, you will lose any settings you have saved.
To reset the unit, you will need a straightened paperclip:
Turn the DVR off.  Poke the straightened paperclip in the unlabeled hole to the left of the Alarm Output connector,
and turn the DVR on.  Hold the switch until the DVR turns on and the live monitoring screen appears.  Release
the reset switch. All of the DVR's settings are now at the original settings it had when it left the factory.

The RS-485 connector can be used to control PTZ (pan, tilt, zoom) cameras. Connect TX+/RX+ or
TX-/RX- of the control system to the RX+/TX+ or RX-/TX- (respectively) of the DVR. See the Camera
