Introduction
Thank you for purchasing a Plextor PlexWriter 4/12max, a CD Reader/Recorder with
the performance and support you expect from Plextor. We appreciate the confidence
you have shown in us. Our goal is to put you ---- and keep you ---- on the leading edge
of CD technology. Throughout the rest of this manual we will occasionally refer to
the PlexWriter by the general model number PX-R412CS, as well as the model
numbers with a lowercase ‘‘i’’ or ‘‘e’’ added to it to indicate internal and external,
respectively.Foryourpurposes,thesereferencesallapplytothePlexWriter4/12CD-R
drive. (CD-R is a common abbreviation for CD Recordable drives and recordable CD
media.)
To get you there, we first have to help you install your PlexWriter 4/12 drive properly
and operate it correctly. After that, the responsibility is yours to seek the applications
that make a CD-R 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
operateyourdrive.Ifyourunintoaproblem,however,pleasecontactus(seeChapter
12 for the different ways you can contact us). You will be connected to our friendly,
helpfulbandof techsupportrepswho know their stuff.What mightseemlike a non-
cooperative CD-R drive to you could very well be a 30-second fix to them. But we
will never know unless you CONTACT 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.
---- CHAPTER 1 ----

This manual is designed to be followed in sequence. It is aimed primarily at those
who will connect their PlexWriter 4/12 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-R412CS 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 PlexWriter 4/12 drives in three configurations:
1) Drive only (includes caddy and Plextor Manager software).
2) Drive with bundled software, including CD-mastering software for PC
2) and Mac, packet writing software and Plextor’s own CD Res-Qsoftware
2) for HDD disaster recovery. (We may add more utilities as we uncover them.)
3) Drive kit with SCSI interface board, the software listed above, cables,
2) media, Plextor Manager, and caddy.
The drive kits come with either ISA or PCI bus mastering SCSI controllers, or PCMCIA
controller for laptops. 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
yourbox were carefully checked before this sticker wasapplied. 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.
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
purchased separately before selling the box to you.
NOTE: Ifyour drive came pre-installed in a computer, therails, cables, interface
boards and other parts shown on the following pages may have been
installed and may not be separately available. Other accessories, espe-
ciallysoftware,maynot havebeen purchasedfromPlextorandthus may
be different from those sold in Plextor retail packages.

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 PlexWriter 4/12 CD-R 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 PlexWriter 4/12 might go through on its way
from us to you. Our box and its packaging material were designed and drop tested to
ensurethatyourPlexWriter4/12canendureroughtreatmentandstillarriveinworking
order.
We advise you to hold on to 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
ontotheirboxesandhavehadtoresorttosomeless-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,pleaseshipyour 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., 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 mustcallour Technical Support Departmenttogetan RMA number
before returning any drive (see Chapter 12, p. 44).

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-R drive.
YOUR METHOD: Inventory your current computer system; check list
below.
If you purchased a Plextor box labeled ‘‘Drive Kit with PCI SCSI Interface’’ or ‘‘Drive
Kit with ISA SCSI Interface,’’ or ‘‘Drive Kit with PCMCIA Interface’’ your needs are
simple: none. Everything you need to successfully install and operate your PlexWriter
4/12 is included in the box you purchased.
If you are a PC owner who has purchased a PlexWriter 4/12 ‘‘Drive Only’’ box, life
gets a bit more complicated. These drives are intended for purchase by computer
resellers or computer enthusiasts. They do not have software, cables, or a SCSI
controller.DriveonlypackagesareforthosewhoneedaPlextorCD-Rdrivebutprefer
to use their own sources for all the accessories. So, if you purchased a drive only, you
will need to select CD-mastering or packet writing software that supports the Plex-
Writer 4/12. You will also need some cables, CD-R media, and a SCSI controller. For
SCSI controller purposes, you fall into one of two groups:
1) You do not own a bus-mastering SCSI interface board.
In this case, you have to get one. Your local computer store and numerous
mail order vendors carry them. Due to the technical demands of producing
your own CDs, it is suggested that you buy a high-performance bus-mastering
interface board. Older PIO SCSI interface boards may not properly support
the recording of CDs. Call us if you need suggestions on which model to buy.
2) You own a bus-mastering SCSI interface board.
If you purchased your SCSI interface board several months or years before you
purchased your PlexWriter 4/12, you may need to update your device drivers.
See the discussion about device drivers in Chapter 9 of this manual.
NOTE: Do not use SCSI interface built into a soundboard.

6PX-R412CS OPERATION MANUAL

If you need to purchase a SCSI cable, note the following:
Internal Cables
You may already have a SCSI ribbon cable. If you are removing an existing internal
SCSI device and installing the PlexWriter 4/12, you can use the same cable. If you are
not removing an existing internal SCSI device, you may need to purchase a different
SCSIribboncablefrom yourlocal computersupplystore.Thecable musthave atleast
as many connectors as you have SCSI peripherals (including one for your PlexWriter
4/12), plus one additional connector to attach to the interface board. Be sure to read
the section on ‘‘Termination’’ in Chapter 7 of this manual.
External Cables
If you have an external PlexWriter 4/12, you will need to purchase an external SCSI
cable. Make sure at least one end of the cable has the same kind of SCSI connector
as your PlexWriter. The other end of the cable must have the proper connector to fit
your SCSI controller or another daisy-chained external SCSI device. Be sure to read
the section on ‘‘Termination’’ in Chapter 7 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.

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 PlexWriter 4/12 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 PlexWriter 4/12 external drive.
✗Donot place yourdriveindirect sunlight, onheatingunits, or near electrical
appliances that 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
contaminants.
✓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-R and CD-ROM discs remain free of dirt or
other contaminants, your drive requires a disc caddy. Use only an industry
standard disc caddy or the tray/caddy adapter included with your drive. Do
not insert a warped or cracked disc caddy into the drive.
✓Keep your CD-R and CD-ROM discs clean. See Chapter 10 for tips on
handling and cleaning 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-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
providethisflexibility,Plextorgivesitscustomersoptionsonhowadrivecanbesetbefore
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/dialsettingsofthePX-R412CSi/PX-R412CSe.Thissectionwilldescribe
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.)

PX-R412CSi Internal Drive
Factory Setting of Jumper Block
The functions shown are ON if the jumpers are installed and OFF if jumpers are
removed. The jumpers are set by the factory as follows:
Installing and Removing Jumpers
Ensure power to the drive is OFF before installing or removing jumpers.
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. Extra jumpers are supplied with the
PX-R412CSi in addition to the three jumpers already installed at the factory.
Caution: Installjumpersacrosseachpinasshown.Donot connectonepinswitch
to another by installing the jumpers lengthwise. Doing so could result in
damage to the drive. ONLY when upgrading firmware are jumpers
connected lengthwise.
