Connecting to the RS232 Port

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

The DVR has a Factory Reset switch under the RS232 connector. 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 RS232 connector.
4. Hold the switch until all the LEDs and all the segments on the Front Panel Display are
lit.
NOTE: When the DVR successfully resets to factory defaults all the LEDs and the
segments on the Front Panel Display flash three times.
