---- CHAPTER 1 ----
Introduction
Thank you for purchasing a Plextor 4PleX CD-ROM drive. We appreciate the
confidence you have shown in our ability 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 4PleX 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 (Mac
people have it easy). Fear not. We have successfully walked through the installation
process with many customers who previously had lived in mortal terror of the innards
of their computer.
In this manual you should find all the information you need to successfully install and
operate your drive. However, if you run into a problem CALL US (see Chapter 14 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 reps
drives. What might seem like a lost cause to you could very well be a 30 second fix
to them. But we will never know unless you CALL US. If you are having trouble, 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.
who know their stuff about CD-ROM
This manual is designed to be followed in sequence. It is aimed primarily at those
who will connect their 4PleX 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:

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 configuration 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 4PleX drives in four configurations:
1) Drive Only
2) Drive with 16-bit SCSI Interface Board Kit
3) Drive with16-bit Soundboard Kit
4) Drive with Mac Kit
The configuration you received is indicated by stickers applied to your box.
PLEASE
NOTE:
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.
A security sticker was applied to the top of your box. The contents of your
box were carefully checked before this sticker was applied. If it was 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.

CHAPTER 2 ---- Box Contents
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, fill it with
the Plextor box.
If you received your 4PleX 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 4PleX 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 4PleX 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
onto their boxes, and have had to resort to some less-than-secure methods to get drives
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, please ship your drive in the safest manner possible. We believe your drive
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., Mailboxes, 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 tech 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 14, p. 65).

---- CHAPTER 3 ----
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 16-bit
SCSI Interface Kit’’ or ‘‘Drive with 16-bit Soundboard Kit’’ your needs are simple: none.
The same holds true if you are a Mac owner and purchased a Plextor box labeled
‘‘Drive with Mac Kit.’’ Everything you need to successfully install and operate your
4PleX 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 a 4PleX ‘‘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 which 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
model to buy. You also will need to buy a SCSI ribbon cable to connect the
board to an internal drive, or an external SCSI cable to connect the board
to an external drive.
2) You own a SCSI interface board.
If you already have other SCSI peripherals (e.g., hard disk, scanner, tape
drive) connected to the board, you will need a daisy chain cable that can
connect one board to multiple SCSI peripherals. If you have a SCSI interface
board, but the CD-ROM drive is the only SCSI peripheral you will connect
to it, you can use cables such as those mentioned in #1 above.
If you purchased your SCSI interface board several months or years before
you purchased your 4PleX 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 add a SCSI cable and, most important, an audio cable (see
page 33 for a discussion on audio cables). If you have an external drive you
6 PX-43CH/PX-45CH OPERATION MANUAL
Page 13
CHAPTER 3 ---- What Else Do I Need?
will need two SCSI cables (internal and external), an audio cable, and a
special bracket that plugs into the back of your computer. The bracket acts
as the point where cables inside your computer connect to cables outside
your computer (and onto your CD-ROM drive).
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 4 ----
Precautions
YOUR TASK: Read the list of precautions below.
YOUR OBJECTIVE: Avoid any undo harm coming to you or your drive.
YOUR METHOD:
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.
Review the list and use common sense.
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 PX-45CH external drive.
✗ Do not place either the PX-43CH or PX-45CH drive in direct sunlight, on
heating units, or near electrical appliances which draw large amounts of
current, such as a high-powered audio amplifier, microwave oven, toaster,
hair dryer, etc.
✓ Keep the area around your drive clean from dust, smoke, and other contami-
nants.
✓ Use a soft, dust-free cloth for cleaning your drive. Do not allow moisture or
liquids including water, cleaning fluids, or solvents to touch the drive.
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 11 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.
Only CD-ROM discs carrying this label may be used with this drive:

---- CHAPTER 6 ----
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 4PleX 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.
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-43CH and the switches
and rotary dial found on the rear panel of the PX-45CH 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-43CH / 45CH. This section will
describe how to make these changes. For information on #2 and #3, see page 17.
If the CD-ROM drive is the only SCSI peripheral you will use with your computer, you
do not need to boot from the CD-ROM drive in a UNIX environment. If you do not
plan to use the Eject Lock feature, skip now to Chapter 8, Hardware Installation. (Take
our word for it, most of you can now skip to Chapter 8.)

Installing and Removing Jumpers
Ensure power to the drive is OFF before installing or removing jumpers.
Identify the appropriate pin number by looking for the pin labeled 1 on the green
circuit board. The pins to the right of it are 2, 3, 4, 5, 6, 7 and 8 respectively.
To remove a jumper, pull it off with your fingers or a pair of needle-nose pliers.
To add a jumper, push it onto the jumper pins. Three extra jumpers are supplied with the
PX-43CH in addition to the three jumpers already installed at the factory.
Caution:
Install jumpers

CHAPTER 6 ---- Drive Switch/Jumper/Dial Settings
SCSI ID Number
It is possible to chain (using a daisy chain cable) up to seven SCSI peripherals to a
single SCSI interface board, or to the SCSI port of an Apple computer. However, when
using multiple SCSI peripherals, it is necessary to set each peripheral to a unique SCSI
ID number.
Your Plextor CD-ROM drive can be set to use one of eight SCSI ID numbers. The drive
should arrive with its SCSI ID set to 2. Accordingly, if you already use another SCSI
peripheral and its SCSI ID also is set to 2, you must change the SCSI ID number of
either this peripheral or the CD-ROM drive.
Changing the SCSI ID: PX-43CH
The SCSI ID number of the PX-43CH is determined by the placement of jumpers on
pins 1, 2 and 3. To change the SCSI ID number, follow the chart below.
Jumper Installed Across
SCSI ID Number Pin 1 Pin 2 Pin 3
0 No No No
1 YES No No
Factory
Settings
2 No YES No
3 YES YES No
4 No No YES
5 YES No YES
6 No YES YES
7 YES YES YES
For example, the factory setting of the SCSI ID at 2 is made by installing a jumper
across pin 2 of the jumper block, leaving pins 1 and 3 uncovered. To set the SCSI ID
at 7 you would install a jumper across pin 1, another jumper across pin 2, and a third
jumper across pin 3. To set the SCSI ID at 5, you would install a jumper across pin 1
and a jumper across pin 3, leaving pin 2 uncovered.

CHAPTER 6 ---- Drive Switch/Jumper/Dial Settings
Auto Leave this ON unless you are having trouble reading a defective or damaged
CD-ROM disc.
Normally, the data transfer rate for the drive is 600KB/sec from the data
section of the disc and 150KB/sec from the audio section. However, your
drive is designed to sense if it is reading a defective, damaged or poorly
manufacutred disc and adjust the data transfer rate accordingly.
With the AUTO switch ON, the drive first will attempt to read a disc at quad
speed (600KB/sec). If it is unsuccessful, the drive automatically will switch
to double speed (300KB/sec) and once again attempt to read the disc. If
successful, the drive will continue at double speed until it receives the next
read command. At this point, it will attempt to resume quad speed operation.
If your drive is unsuccessful in reading a disc at quad or double speed, it will
slow to single speed (150KB/sec) and try a final time to read the disc. If
successful, the drive will continue at single speed until it receives the next
read command. At this point, it will attempt to resume quad speed operation.
If it is unsuccessful in its attempt to read a disc at single speed, you will
receive an error message.
You may override this feature and set your drive to operate only at single
speed (150KB/sec) by setting the AUTO switch/jumper OFF. At this setting,
the drive will transfer both data and audio at 150KB/sec.
We recommend that you set this switch/jumper OFF only under extreme
circumstances (e.g., you have a badly damaged disc that you MUST get data
from).
Test Leave this OFF. It is for factory use only.
Block Leave this OFF unless you are working in an UNIX environment and want
to boot from your CD-ROM drive. If so, set this switch/jumper ON.
Eject In most situations, you will want to leave this switch/jumper OFF.
However, if you are in an environment where you want to prevent others
from borrowing or stealing the disc inserted in your drive (e.g., the drive is
located in a public place where multiple people hae unlimited access), you
can activate the Eject Lock feature. To do so, set this switch/jumper ON.
When this switch/jumper is ON, it is impossible to eject a disc inserted in
the drive by pressing the Eject button. A software eject command must be
issued for the disc to eject from the drive. Check your device driver manual
for instructions on how to issue a software eject command.

Termination
YOUR TASK: Find the location of the terminator(s) on your drive.
YOUR OBJECTIVE: Determine if your drive must use a terminator(s).
YOUR METHOD:
Find location of terminator(s) by checking diagrams
in Chapter 5. If necessary, remove them by
following instructions given below.
You must use a terminator if the PX-43CH or PX-45CH is the only SCSI peripheral
used with your computer. In addition you must use a terminator if you are using
multiple SCSI peripherals with your computer, and the PX-43CH or PX-45CH is
positioned as the
Any SCSI peripherals which are positioned between your SCSI host adapter and the
last peripheral in a daisy chain should have their terminators turned OFF. Consult the
manuals of these peripherals for the proper method of turning their terminators OFF.
Remember:

or PX-45CH, you must turn OFF the PX-43CH’s or PX-45CH’s termination.

CHAPTER 7 ---- Termination
PX-43CH Termination
The PX-43CH is shipped from the factory with its termination turned ON. To turn
termination OFF remove the black resistor blocks from the locations shown below:
Top panel of drive
White Dot
Resistor Block
Front door
If your drive already is installed in your computer, be sure to turn off your computer
power before removing (or reinstalling) the terminators. We recommend that you use
needle nose pliers to remove the resistor blocks in order to avoid bending their legs.
We also recommend that you retain the resistor blocks so you can reinsert them into
the drive if you later need to turn the drive’s termination ON. If you reinsert the resistor
blocks, make sure that the side of the resistor block with a small white dot is facing
UP.
PX-45CH Termination
The PX-45CH is shipped from the factory with a terminator installed on one of its SCSI
connectors on the rear panel of the drive. When this terminator is installed, the drive’s
termination is turned ON.
To turn the termination OFF, first turn off the drive’s power, then pull the terminator
off the SCSI connector. We recommend that you retain the terminator so that it can
be reinstalled if you later need to turn the drive’s termination ON.
