Drive Switch/
Jumper/Dial Settings
YOUR TASK:
Find the location of jumpers (internal drive) or
switches and rotary dial (external drive). Check
their settings. Change them if necessary.
YOUR OBJECTIVE:
To ensure that your new CD-R drive can coexist
peacefully with other equipment you might have
installed in your computer. To ensure that your
drive will work properly after it is installed.
YOUR METHOD:
Find locations of jumpers/switches/rotary dial on
diagram in Chapter 5. Read below to determine if
your drive’s settings need to be changed. If so, follow
the directions on making the necessary changes.
Your PlexWriter 4/12 needs to be flexible enough to work with the variety of computer
systems (PC, Mac, Sun, Silicon Graphics, DEC, etc.) that can use SCSI peripherals. To
provide this flexibility, Plextor gives its customers options on how a drive can be set before
it is installed. On an internal drive, settings are determined by the position of jumpers on
the jumper block at the rear of the drive. On an external drive, settings are determined by
the position of DIP switches and the rotary dial on the rear panel of the drive.
Fortunately, we have a pretty good idea of the environment in which most of our
drives will be used (a single SCSI device connected to a PC or Mac). Your drive ships
from our factory with its jumpers/switches/dial set to work in this environment.
You should leave the jumpers found on the rear panel of the PX-R412CSi and the
switches and rotary dial found on the rear panel of the PX-R412CSe at their factory
settings unless: 1) you plan to use another SCSI peripheral (e.g., hard disk, scanner)
with your computer system in addition to your CD-R drive; 2) you find it necessary to
change the device type setting (most likely in an older UNIX system); or 3) you need
to upgrade the drive’s firmware.
If you plan to use additional SCSI peripherals, you may need to change the
jumper/switch/dial settings of the PX-R412CSi/PX-R412CSe. This section will describe
how to make these changes. For information on #2 and #3, see page 18.
If the CD-R drive is the only SCSI peripheral you will use with your computer and you
do not need to change the device type setting, skip now to Chapter 8, Hardware
Installation. (Take our word for it, most of you can now skip to Chapter 8.)
