Notice!
1. If there is any time-overlapped data (ex: DST etc.) among the recorded data you want
to back up, the window which you can select the one of time-overlapped data will pop
up and “Search”(ITEM5) will be done according to the selected data.
2. When the DVR is under HDD overwriting mode, back up can be done from the data of
more then 1 hour later of “Recorded start time”
(Because when the overwriting is on working, the “Recorded start time” is changing continuously)
The RS-232C port has two main functions, PC to DVR update using a DB9 cable, and PTZ control using a RS-485
to RS-232C adapter. The settings required for both functions vary depending on the devices specifications. Please
refer to the devices operational manual for the required baud rate, data bits, stop bit, and parity settings to establish
communication between devices.

Baud Rate
The baud rate setting is used to determine the speed setting between the DVR and external
device using the RS-232C port. The RS-232C port uses two voltage states commonly known as
MARK (negative) and SPACE (positive).
The baud rate will vary depending on the required settings of the external device used with the
RS-232C port. Please refer to the operational manual of the device.

Data Bits
