CHAPTER 6 ---- Drive Switch/Jumper/Dial Settings

SCSI ID Number

It is possible to chain (using a daisy chain cable) up to seven SCSI peripherals to a
single SCSI interface board, or to the SCSI port of an Apple computer. When using
multiple SCSI peripherals, however, it is necessary to set each peripheral to a unique
SCSI ID number.
Your Plextor CD-ROM drive can be set to use one of eight SCSI ID numbers. The drive
should arrive with its SCSI ID set to 3. Accordingly, if you already use another SCSI
peripheral, and its SCSI ID also is set to 3, you must change the SCSI ID number of
either this peripheral or that of the CD-ROM drive. In the past this always had to be
done manually. If you connect your UltraPleX to an existing SCSI controller, you will
still need to go through this exercise of checking and possibly changing SCSI IDs. If,
instead, you bought a Plextor kit with a SCSI interface board, both the drive and the
board are SCAM* compliant. Each time you turn on your computer, the drive will
internally reset its SCSI ID to avoid any conflict. If you separately purchased or already
own a SCSI interface board, it may
Changing the SCSI ID: PX-32XSi
The SCSI ID number of the PX-32XSi is determined by the placement of jumpers on
pins 1, 2, and 3. To find the location of pin 1, pin 2, and pin 3, refer to the diagram
of the Jumper Block on the previous page. To change the SCSI ID number, follow the
chart below.
