PlexWriter 12/10/32S Operation Manual
Set SCSI Drive
Switches or Jumpers
Your PlexWriter SCSI drive needs to
be flexible enough to work with the
variety of computer systems and a
number of other SCSI peripherals. To
provide this flexibility, Plextor lets
you specify the drive’s settings before
it is installed. On an internal SCSI
drive, you determine settings by the
position of jumpers on the jumper
block at the rear of the drive. On an
external drive, you determine settings
by the position of DIP switches and
the rotary dial on the rear panel of the
drive.
Your drive ships from our factory
with its jumpers, switches, and/or dial
set to work in the most commonly
found environment. You should leave
those switches and jumpers at their
factory settings, unless: 1) you plan to
use another SCSI peripheral (e.g.,
CD-ROM, hard disk, scanner) with
your computer system in addition to
your PlexWriter; or 2) you find it
necessary to change the block size
setting (most likely in an older UNIX
system).
Do I Have to Change My PlexWriter’s SCSI ID Number?
Your PlexWriter SCSI drive is shipped from the factory with its SCSI ID number set
to 4. The SCSI interface lets you chain several SCSI peripheral devices to a single
SCSI interface board, or to the SCSI port of an Apple computer, with no loss of
performance.
NOTE: The cable length of all SCSI chain cables should not exceed 1.5 meters.
Shorter cable lengths are better, especially when using multiple devices or faster
SCSI interfaces, such as Ultra, Ultra Wide, and others.
Quickstart Installation
(Continued)
Scenario 2: You have a Plug-and-
Play/SCAM SCSI board installed
already, the PlexWriter is your only
SCSI peripheral, and you have a
Windows operating system.
What to do: Plug in the PlexWriter,
and go. Windows will recognize the
drive and install the correct drivers
automatically.
Scenario 3: You have a SCSI board that
is not Plug-and-Play/SCAM-capable,
and you have a Windows operating
system.
What to do: Set a unique SCSI ID
number for the PlexWriter, and make
sure all other peripherals have their own
SCSI numbers. Set the termination of
each peripheral OFF; except set the
termination of the last peripheral
devices on each side of the chain to ON.
Other scenarios, or if you have
problems: Better take a closer look at
this chapter and at “Appendix B:
Installing a SCSI Drive in Windows.”
