NOTE: Change the SCSI ID number after turning off the power to this drive unit and
computer. The new number will not become effective while power is still turned on.
Setting SCSI ID (external)
For external units, you can change the value on the ID number display
window by turning the SCSI ID switch. If you encounter overlapping
SCSI IDs, reassign the ID numbers. The initial default value “4” is
assigned to all drive units in the factory before shipment. For internal
units, set the SCSI ID with SCSI ID jumpers as shown in the diagram.
In all cases, two consecutive SCSI ID numbers must be available.
A SCSI hint for Mac Users
SCSI ID=0 is assigned to the built-in hard disk drive, SCSI ID=3 to
the built-in CD-ROM drive, and SCSI ID=7 to the computer before
shipment. Therefore, SCSI ID=1, SCSI ID 2, SCSI ID=4, SCSI ID=5,
and SCSI ID=6 are available for this drive unit.
It will therefore be necessary to pay close attention to the SCSI IDs
on your Macintosh, as the PCD-47 requires three SCSI IDs. See
“Setting SCSI IDs” for an explanation of SCSI ID usage.
NOTE: SCSI ID=3 is available when the Macintosh computer has no built-in CD-
ROM drive. For an external CD-ROM drive, SCSI IDs other than “3” may be
assigned. In either case, it is imperative to check the SCSI ID for all SCSI devices.
Also, note that the SCSI ID for the built-in hard disk drive and the computer cannot
be changed.
