Rear USB connector
Three USB ports are provided to connect external hard disk, CD-RW or flash
drives for video clip copying or system upgrades. One USB port is on the rear
panel and the other two are on the front panel. Position external drives close
enough to the DVR so that you can make the cable connections, usually less than
6 feet. Use the USB cable provided with the hard disk drive to connect it to the
DVR.
A USB mouse (not supplied) can be connected to one of the ports. You can use
the mouse to navigate through the screens and menus much like you would on a
computer.
A PostScript™ USB printer (not supplied) can be connected to one of the ports.
You can print selected images resulting from a search. Refer to Section 9.10:
Searching video.
A USB to Serial converter can be connected to the USB port. Multiple text-in
devices can be used with a USB to Serial converter.
