Introduction
Thank you for purchasing a Plextor 8PleX, the first eight speed CD-ROM drive with
professional quality specifications. The 8PleX is also the first eight speed CD-ROM
driveable toself-configure SCSIIDs (whenpurchased inkit formwith aSCSI interface
board or otherwise connected to a SCAM compliant SCSI interface board). We will
discuss this capability in more detail in Chapter 6. Throughout the rest of this manual
we will occasionally refer to the 8PleX as well as the internal and external model
numbers. For your purposes, these references all apply to the 8PleX CD-ROM drive.
We appreciate the confidence you have shown in us. Our goal is to put you----and
keep you----on the leading edge of CD-ROM drive performance. To get you there, we
first have to help you install your 8PleX drive properly, and operate it correctly. After
that, the responsibility is yours to seek the applications that make a CD-ROM drive
such a powerful and exciting addition to your system.
For those of you with PCs, the installation process may seem a bit complicated.
Windows95hasimprovedthingsalittlebit.Macpeoplehaveiteasy.Butnooneshould
worry.Our manualshavesuccessfully walkedmanycustomersthrough theinstallation
process,includingthosewhopreviouslyhadlivedinmortalterroroftheinnardsoftheir
computer. Plus, our Technical Support Department is just a phone call away.
In this manual you should find all the information you need to successfully install and
operate your drive. If you run into a problem, however, CALL US (see Chapter 13 for
the different ways you can contact us). The call is toll-free. You will be connected to
our friendly, helpful band of tech support repswho know their stuff about CD-ROM
drives. What might seem like a lost cause to you could very well be a 30-second fix
tothem.ButwewillneverknowunlessyouCALLUS.Ifyouarehavingtrouble,please
don’t give up, and don’t take your drive back to where you bought it until you have
spoken with one of our tech support reps.
---- CHAPTER 1 ----
This manual is designed to be followed in sequence. It is aimed primarily at those
who will connect their 8PleX drive to a PC.
Mac users should look for this symbol:
Users of UNIX-based systems should look for this symbol: as an
indicator of sections of the manual that pertain to them.
Many of you reading this manual are experienced computer users who have
successfully installed peripherals in the past. There probably are a number of
sections in this manual that you can skip over. However, we ask everyone----from
novice computer users to experienced computer professionals----to read the sections
marked with this symbol:
PX-83CS/PX-85CS OPERATION MANUAL 1

Box Contents
YOUR TASK: Check the contents of the box.
YOUR OBJECTIVE: Make sure you got everything you paid for.
YOUR METHOD: Compare what you find in the box with the tables
on the following pages.
What you should find in your Plextor box depends on two factors: 1) what configu-
ration you purchased; and 2) what the company that sold you the box put in ---- or
took out ---- while it was in their possession.
Plextor currently sells its 8PleX drives in three configurations:
1) Drive Only
2) Drive with SCSI Interface Kit
3) Drive with Mac Kit
The configuration you received is indicated by stickers applied to your box.
Your drive may also have been integrated into a computer system or subsystem
sold by a third party.
PLEASE
NOTE: A security sticker was applied to the top of your box. The contents of
yourboxwere carefully checkedbefore this stickerwas applied. Ifitwas
cut before you purchased the box, you should carefully check the
contents to ensure nothing has been removed. If something is missing,
you should contact the party from whom you purchased the box for an
explanation.
There may be a perfectly good reason why the security sticker on the box was cut
before you received it. For example, a dealer may have purchased a ‘‘Drive Only’’
configuration from Plextor, then added a SCSI interface board and/or software he had
purchased separately before selling the box to you.
NOTE: Ifyourdrive came pre-installedin a computer,the rails, cables,interface
boards, and other parts shown on the following pages may have been
installed and may not be separately available.

A Gentle Reminder. . .
YOUR TASK: Save your box (if you received one).
YOUR OBJECTIVE: Have a secure container in which to ship your drive
back to Plextor, if necessary.
YOUR METHOD: Find an empty space in your home/office and fill it
with the Plextor box.
If you received your 8PleX CD-ROM drive in a Plextor box, you should save the box
after you have installed your drive. There are many sets of hands----some of them
potentially unfriendly----that a drive might go through on its way from us to you. Our
box and its packaging material were designed and drop tested to ensure that your
8PleX drive can endure rough treatment and still arrive in working order.
We advise you to hold onto your box in case you should ever need to return your
drive to Plextor for any reason. Unfortunately, some of our customers have not held
ontotheirboxes,andhavehadtoresorttosomeless-than-securemethodstogetdrives
back to us. We have received drives in a shoebox, in an unpadded express mail
envelope, and in a box filled with buttered popcorn.
We cannot assume liability for any damage your drive sustains during shipment.
Therefore,pleaseship yourdrivein thesafest manner possible.We believe yourdrive
will be most secure if it is shipped in a Plextor box. We hope you will never have to
ship your drive back to us. If you do, however, we hope you will send it packaged in
a Plextor box.
If you did not receive a Plextor box (if, for example, your drive came pre-installed in
a computer), we recommend that you pay a packaging store (e.g., Mail Boxes Etc.) in
your area to ship your drive. The drives that we have received from most packaging
stores have arrived in good shape. If you don’t have a packaging store in your area,
call our Technical Support Department for packaging pointers before you ship your
drive. In fact, you should call our Technical Support Department to get an RMA
number before returning any drive (see Chapter 13, p. 63).

PX-83CS/PX-85CS OPERATION MANUAL 5

What Else Do I Need?
YOUR TASK: Review the software and hardware installed in your
current computer system.
YOUR OBJECTIVE: Determine what else you may need to operate your
CD-ROM drive.
YOUR METHOD: Inventory your current computer system; check list
below.
If you are a PC owner and you purchased a Plextor box labeled ‘‘Drive with SCSI
InterfaceKit’’yourneedsaresimple:none.ThesameholdstrueifyouareaMacowner
and purchased a Plextor box labeled ‘‘Drive with Mac Kit.’’ Everything you need to
successfully install and operate your 8PleX CD-ROM drive is included in the box you
purchased. The only thing you need to add is a CD-ROM disc to play in your new
drive.
If you are a PC owner who has purchased an 8PleX ‘‘Drive Only’’ box, life gets a bit
more complicated. You fall into one of three groups:
1) You do not own a SCSI interface board.
In this case, you have to get one. Your local computer store and numerous
mail-order vendors carry them. Call us if you need suggestions on which
modeltobuy.WehaveprovidedaninternalSCSIribboncableoranexternal
SCSI cable to connect the board to your new 8PleX CD-ROM drive.
2) You own a SCSI interface board.
If you have only one other internal SCSI peripheral device and a Plextor
internal CD-ROM drive, you can use the SCSI ribbon cable we provided. If
you have more than one other internal SCSI peripheral, you will need to
purchase a different SCSI ribbon cable from your local computer supply
store. The cable must have at least as many connectors as you have internal
SCSI peripherals (including one for your Plextor CD-ROM drive), plus one
additional connector to attach to the interface board.
If you have an external Plextor CD-ROM drive, you will be able to include
it in your daisy chain of other external SCSI peripherals with the cable we
have provided (if at least one of your other peripherals has the same kind of
50-pin, high-density SCSI connectors as your Plextor drive). Be sure to read
the section on ‘‘Termination’’ in Chapter 7 of this manual.
---- CHAPTER 3 ----
6PX-83CS/PX-85CS OPERATION MANUAL

If you purchased your SCSI interface board several months or years before
you purchased your 8PleX drive, you may need to update your device
drivers. See the discussion about device drivers in Chapter 9 of this manual.
3) You own a soundboard that has a SCSI interface built into it (e.g., Sound
Blaster SCSI II).
You may need to use the SCSI cable and, most important, the audio cable
we have included with your 8PleX (see page 33 for a discussion on audio
cables). If you have an external drive, you will also need a special bracket
connector and an internal SCSI cable. These should have been provided by
the soundboard manufacturer. They allow the internal SCSI connector on
your soundboard to be linked or connected to your external drive. If they
were not provided by your soundboard manufacturer, you will need to
purchase them from a local computer supply store.
You also may need to update your device drivers. See the discussion about
device drivers in Chapter 9 of this manual.
Once you have assembled everything you need, you’re ready to install your drive.
But first, a few words of caution are in order.
CHAPTER 3 ---- What Else Do I Need?
PX-83CS/PX-85CS OPERATION MANUAL 7

Precautions
YOUR TASK: Read the list of precautions below.
YOUR OBJECTIVE: Avoid any undo harm coming to you or your drive.
YOUR METHOD: Review the list and use common sense.
Your new CD-ROM drive is a precision electromechanical device. Like the rest of
your computer system, it requires reasonable care in its installation and use.
Please read this manual carefully and keep it handy for easy reference. Use this
manual for installation, operation, and troubleshooting. See your dealer, or call
Plextor’s Technical Support Department, should your drive require repair or service.
✗Do not put your computer monitor (or any other device weighing more than
30 lbs.) on top of the 8PleX external drive.
✗Donot placeyour drivein directsunlight, onheating units,or nearelectrical
appliancesthatdrawlargeamountsofcurrent,suchasahigh-poweredaudio
amplifier, microwave oven, toaster, hair dryer, etc.
✓Keep the area around your drive clean from dust, smoke, and other
contaminants.
✓Use a soft, dust-free cloth for cleaning your drive. Do not allow moisture or
liquidssuch aswater,cleaning fluids,or solventsto touchthedrive.Thinner,
benzene, or alcohol-based solvents can mar your drive’s surface.
✓To help ensure that your CD-ROM discs remain free of dirt or other
contaminants, your drive requires a disc caddy. Use only an industry
standard disc caddy. Do not insert a warped or cracked disc caddy into the
drive.
✓Keep your CD-ROM disc clean. See Chapter 10 for tips on handling and
cleaning CD-ROM discs.
✗Do not drop or jolt the drive.
✗Do not attempt to open the drive and service it yourself. Removing the cover
may expose you to harmful electrical voltages or the laser beam. For your
safety, entrust service to Plextor-authorized service personnel only.

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-ROM 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 8PleX CD-ROM drive 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.
NOTE: Silicon Graphics computers are somewhat proprietory and historically you
needed to buy a Silicon Graphics C-ROM drive. Now you can purchase
special kits from Plextor that are specially configured for SGI.
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.
YoushouldleavethejumpersfoundontherearpanelofthePX-83CSandtheswitches
and rotary dial found on the rear panel of the PX-85CS 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-ROM drive; 2) you work in a UNIX
environment and want to boot from your CD-ROM drive; 3) you want to utilize the
Eject Lock feature. If you plan to use additional SCSI peripherals, you may need to
change the jumper/switch/dial settings of the PX-83CS/85CS. This section will further
describe how to make these changes. For more information on #2 and #3, see page 17.
---- CHAPTER 6 ----
