RS485 Port

The DVR can be controlled remotely by an external device or control system, such as a control
keyboard, using RS485 half-duplex serial communications signals. The RS485 connector can also
be used to control PTZ (pan, tilt, zoom) cameras. Connect RX+/TX+ and RX-/TX- of the control
system to the + and – (respectively) of the DVR.

RS232 Port

An RS232 port is provided to connect remote control devices such as a control keyboard. PTZ
cameras or text-in devices can also be connected to the RS232 port.

Network Port

The DVR can be networked using the 10Mb/100Mb/1Gb 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.
CAUTION: The network connector is not designed to be connected directly with cable or
wire intended for outdoor use.

Video Out

A VGA connector is provided so that you can use a standard, multi-sync computer monitor as your main monitor.
Use the cable supplied with your monitor to connect it to the DVR.
An HDMI (High-Definition Multimedia Interface) connector is provided so that you can use an HDMI monitor
as your main monitor.

Factory Reset Switch

The DVR has a Factory Reset switch to the left of the HDMI connector on the rear panel.
This switch will only be used on the rare occasions that you want to return all the settings to
the original factory settings.
CAUTION: When using the Factory Reset, you will lose any settings you have saved.
To reset the unit, you will need a straightened paperclip:
1. Turn the DVR off.
2. Turn it on again.
3. While the DVR is initializing, the front panel LEDs will blink. When the front panel LEDs blink, poke
the straightened paperclip into the unlabeled hole to the left of the HDMI connector.
4. Hold the switch until the DVR's internal buzzer sounds twice.
5. Release the reset switch. All of the DVR's settings are now at the original settings it had when it left the factory.

NOTE: Connect the monitor before the DVR boots so that video can be displayed
on the monitor with the resolution you have set during system setup. If you want
to use both the HDMI and VGA Monitor connectors, one of the monitors should
be connected before the DVR boots, and the other monitor should be connected
after the DVR boots.
