Setting Switches on a PlexWriter External SCSI Drive
Use this procedure if you have a PlexWriter external SCSI drive. (However, if you
already have a SCSI board installed, an external PlexWriter is the only SCSI
peripheral you will use with your computer, and you do not need to change any
settings, skip now to “Install a PlexWriter External SCSI Drive” on page 24.)
Factory SCSI Switch Settings
A rear-panel rotary dial controls the SCSI ID setting of the external PlexWriter drive,
and other settings are controlled by DIP switches. Figure 9 shows the factory settings
of the rear-panel dial and switches.
Figure 9: Factory Settings for Dial and DIP Switches on External SCSI Drive
CAUTION: Turn the drive’s power OFF before changing the setting of the SCSI ID
dial or the DIP switches.
Changing the SCSI ID
If you already have another SCSI peripheral whose SCSI ID is set to 4, you must
change the SCSI ID number of either that peripheral or that of the PlexWriter drive.
(But see “Do I Have to Change My PlexWriter’s SCSI ID Number?” on page 10
before proceeding.)
To change the SCSI ID number of the external PlexWriter drive, rotate the dial’s
arrow to a different SCSI ID number.
