A PostScript™ USB printer (not supplied) can be connected to one of the ports. You can print selected
images resulting from a search.

Connecting to the RS232 Port
Figure 15 — 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.
Connecting to the Ultra Wide SCSI Port
Figure 16 — SCSI connector.
A SCSI port is provided to connect external storage devices for recording or archiving 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 5 feet (1.5 meters). You can connect up to 8 UltraWide SCSI
devices with SCSI IDs set from 0 to 15 except for 7, which is assigned as the Host ID.
NOTE: The SCSI bus must be terminated, otherwise the DVR will not operate properly.
NOTE: When using low speed SCSI devices, the recording speed might decrease.
CAUTION: Do NOT connect or disconnect SCSI devices while the DVR power is on. The
DVR must be powered down to connect or disconnect SCSI devices. Power up SCSI
devices so they are ready for operation before powering up the DVR. Power down SCSI
devices after powering down the DVR and then disconnect SCSI devices.
CAUTION: If the SCSI device is shut down while the device is operating, the DVR system
might not operate normally.
