Connecting to the RS232 Port
Figure 14 — RS232 connector.
An RS232 port is provided to connect an external modem for remote monitoring, configuration
and software upgrades, and to connect a remote control keyboard. Use a modem cable with a
DB-9S (female) connector to connect to the DVR. See
Chapter 3 — Configuration for
configuring the modem.
NOTE: The DVR is not supplied with a modem cable, and many modems are not
supplied with cables. Make certain you have the correct cable when purchasing the
modem.
Factory Reset
Figure 15 — Factory reset switch.
The DVR has a Factory Reset switch to the right of the USB port. 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 setting you have
made.
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, poke the straightened paperclip in the unlabeled hole to
the right of the USB port.
4. Hold the switch until all the LEDs on the front panel are lit.
NOTE: When the DVR successfully resets to factory defaults all the LEDs on the front
panel flash three times.
5.
Release the reset switch. All of the DVR’s settings are now at the original settings it
had when it left the factory.
