Connecting to the USB Port
Figure 12 — USB connector.
Two USB ports are provided to connect external hard disk drives, CD-RW or flash drive for clip
copy or system upgrade. Position the external hard disk drive 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.
Connecting to the Ultra Wide SCSI Port
Figure 13 — SCSI connector.
A SCSI port is provided to connect external storage devices for recording or arching video.
Connect the external SCSI hard disk drive (RAID) cable to the high-density 68-pin female
UltraWide SCSI port. The length of SCSI cable should not exceed 1.5 meters. You can connect
up to 15 UltraWide SCSI devices with SCSI IDs set to 0, 1, 2, 3, 4, 5, 6, 8, 9, 10, 11, 12, 13, 14
and 15 respectively.
NOTE: Do NOT set the SCSI ID to 7 because the ID number 7 was assigned to the Host.
NOTE: The SCSI bus must be terminated properly, otherwise the DVR will not operate
properly.
CAUTION: Do NOT connect the SCSI device while the DVR power is on. The
DVR must be powered down to connect the SCSI device and powered up again
after the SCSI device has been connected. Power up the SCSI device so it is
ready for operation in advance of powering up the DVR.
CAUTION: If the SCSI device is shut down while the device is operating, the
DVR system may not work normally.
