Installation
2
Connect the power cable.
¶
When the power cable has been connected, the wiring
monitor indicator on the rear of the drive (orange) will
light up.
¶
When terminator switch is set to ON, the termination
indicator (green) also lights (does not apply to DVD-
R7783).
3
Connect the changer interface cable.
¶
When the changer interface cable has been connected,
the wiring monitor indicators will flash at two-second
intervals.
NOTE:
Connect the changer interface cable to the connector
corresponding to the bay in which the drives have been
installed. (Note that labels are affixed to connectors indicating
the corresponding bay number.) Note that it is extremely
important to do this, as connecting the changer interface cable
to a neighboring bay will result in damage to discs and the
disc transport mechanism.
(3) Reading and self-checking the installed drive’s SCSI
ID by the changer
¶
If all drives have been assigned different SCSI IDs, a
buzzer will sound once.
¶
If the same SCSI ID has been assigned to two or more
drives, a buzzer will sound three times.
NOTES:
¶
If installed drives are to be connected to different SCSI
buses, then the same SCSI ID assigned to each of the
drives may be all right.
¶
Even if none of the drives installed within a changer has
been assigned the same SCSI ID, it is necessary to check
that the same SCSI ID is not assigned to other devices
(e.g., hard disks) on the same SCSI bus.
4. Connecting SCSI cables
After installing all drives and checking to make sure that they
have been properly connected, install the SCSI interface
cables.
For SCSI connections refer to the “SCSI Connection
Manual” or consult your dealer.
NOTES:
¶
Host adapter should be set to ID 7.
¶
The LVD SCSI bus should have a total length of 12 m or
less, and SE SCSI bus should have a total length of 6 m or
less (these lengths include wiring inside changers and
between changers when multiple changers are daisy-
chained). However, if the DRM-ULV16 is installed, SE SCSI
bus length should be 3 m or less, and no more than 3
drives can be connected to the bus. As a result, a maximum
of 3 SE drives can be installed on a single changer, and
due to the limitations on cable length, drives should be
installed in the rear bays #1 to #3.
¶
When connecting SE drives, if one or more unused
connectors remain on the SCSI cable, the connector on
the end of the cable should be connected to the terminating
drive, and unused connectors allowed to remain the middle
of the cable (see page 18, examples 1, 3, 4, 6).
¶
The changer SCSI termination switch is set to ON at the
time of shipment. Always make sure that the changer SCSI
termination switch is set to OFF when the changer is not
the last device in the SCSI chain (see page 18, examples
1, 3, 4, 6).
¶
Note that the DRM-7000/DRM-3000 is unable to recognize
the existence of faulty SCSI cable connections or mistakes
in the assignment of SCSI IDs, and for this reason you
should always be sure to restart the host computer after
installation to make sure that all drive units and the changer
are properly recognized. This is the only way of confirming
that all SCSI devices are installed properly.
¶
When connecting a host computer, turn off power to both
changer and host computer before performing the
connection. After connections are completed, turn on
power to the changer first, followed by power to host
computer.

When inserting a drive, be sure to place the drive on the
changer guide rails and push the drive in until the lock
lever on the drive shifts to the locked position. Maybe you
can hear a clicking sound then.
