PX-R820T OPERATION MANUAL
Drive Switch/Jumper/Dial Settings
YOUR TASK: Find the locations of the jumpers (internal drive), the
switches, and the rotary dial (external drive). Check
their settings. Change them, if necessary.
YOUR OBJECTIVE: To ensure that your new CD-R drive can coexist 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 the locations of the jumpers, the switches, and
the rotary dial on the diagram in Chapter 5. Read
below to determine if your drive’s settings need to be
changed. If so, follow the directions for making the
necessary changes.
Your PlexWriter 8/20 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 the drive’s settings 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, and/or dial set to work in this
environment.
You should leave the jumpers found on the rear panel of the PX-R820Ti and
the switches and rotary dial found on the rear panel of the PX-R820Te 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
CD-R drive; or 2) you find it necessary to change the device type setting (most
likely in an older UNIX system).
If you plan to use additional SCSI peripherals, you may need to change the
jumper, switch, and/or dial settings of the PX-R820Ti/PX-R820Te. This section will
describe how to make these changes.
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.)
