Plextor ULTRA-B Assembly Instructions

Hardware Installation
By itself, your CD-ROM drive is incapable of communicating with your computer.
You must use a hardware link that enables your drive to ‘‘talk’’ with the rest of your
computer.
Plextor’s UltraPleX drives use a SCSI interface as their link. If you own a PC, there are
four ways in which you can make the SCSI connection:
1) Use a separate SCSI interface board. This is the most common method for
both internal and external drives. We recommend using a 32-bit PCI bus
masteringSCSIinterfaceboardtomaximizethedrive’spotential.Older8-bit
SCSI interface boards are not recommended. More cost-effective, but with
adecreaseinvideoperformance,are16-bitISAbusmasteringSCSIinterface
boards. Both these bus mastering interface technologies also allow you to
take advantage of SCSI multitasking in 32-bit operating systems such as
Windows 95, Windows NT, UNIX, SCO, Solaris, etc. Another possibility is
to use an ISA-PIO SCSI interface board, but performance will suffer, as will
multitasking.
2) Use a soundboard that also has a SCSI interface built onto it. This helps save
a slot in your computer by combining the functions of two boards (SCSI
interface board and soundboard) into one. Plextor recommends against
using the SCSI interface on a soundcard with the UltaPleX. Doing so will
limit the performance of the UltraPleX.
3) If you have an external drive, you can also use a parallel-to-SCSI interface.
Thisisadevicethatplugsintotheparallelport(theoneyourprinternormally
is connected to) of your computer. It is convenient, but typically at a cost of
reduced performance to your CD-ROM drive.
4) If you have an external drive and a portable computer with a PCMCIA slot
(Type II or III), use a PCMCIA-to-SCSI card. This is a small, credit-card size
device that plugs into the PCMCIA slot. It too is convenient, but may also
provide less performance than a direct connection to a 32-bit or 16-bit SCSI
interface board. PCMCIA connections should, however, provide better
performance than a parallel-to-SCSI interface.
NOTE: The following section is only for PC users who need to install a SCSI
interface board, or a soundboard with a built-in SCSI interface, in their
computer. If you plan to use a parallel-to-SCSI, or PCMCIA-to-SCSI
interface,youcanskiptoChapter9.IfyouareaMacuserwithanexternal

ULTRAPLEX OPERATION MANUAL 21

Board Installation
YOUR TASK: Install a SCSI interface board, or a soundboard with
a built-in SCSI interface, in your computer.
YOUR OBJECTIVE: Provide the hardware link needed to enable your
CD-ROM drive to communicate with your
computer.
YOUR METHOD: Remove your computer’s case. Install board and
attach necessary cables.
Let us point out that this is a CD-ROM drive installation and operation manual----it is
not a SCSI interface board or soundboard installation and operation manual. Unless
you purchased a SCSI interface board or soundboard (and its accompanying manual)
bundled in the same box with an UltraPleX drive, we have no way of knowing which
type of board you elect to use. There are dozens of SCSI interface boards and
soundboards on the market. Each one is installed somewhat differently. Therefore, our
instructions for this section should only be considered as guidelines. For more detailed
instructions on how to properly install your SCSI interface board/soundboard, you
shouldrefertotheinstallation/operationmanualthatyoureceivedwhenyoupurchased
the board.
Caution: If static electricity may be present in the room where you are working,
dischargeanyyoumayhaveonyourbodybytouchingagroundedobject
before you remove the host adapter from its packaging.
Static electricity is a silent killer. Just a small jolt to one of the chips on
your interface board may render it useless with no apparent damage
visible. Positioning your computer in a location without a carpet under-
foot is one method of guarding against static electricity damage. Using
common sense, such as not walking on a carpeted floor in stocking feet
just before you install your drive, is another.
Before proceeding, make sure the power to your computer and any
external peripherals is OFF and your computer is UNPLUGGED from its
power source.

back panel of your computer and sliding off your computer’s cover.
Carefully remove the SCSI interface board from its packaging. Select a vacant slot in
your computer where you will install the board (refer to the manual packaged with
your interface board for instructions as to which slot in your system to use). Plextor

drive, try to pick a slot that is closest to where the drive will be installed.
Remove the cover plate for this slot from the back panel of your computer. Keep the
screw from the cover plate nearby as you will need it in a moment. Save the cover
plate in case you need it at a later date.
Plug the SCSI interface board into the slot you have selected. Rock the board from
end to end to ensure that it seats firmly in the slot. Don’t force it. If you cannot push
the board down completely into the slot, remove the board and try again.

YOUR OBJECTIVE: Position the drive in the proper manner so that it
operates correctly.
YOUR METHOD: If you have an internal drive, find an open bay in
your computer. If you have an external drive, find
an open space on your desktop.

NOTE: The following section is only for those installing internal drives. If you
have an external drive, skip to page 30.
Mounting an Internal Drive
YOUR TASK: Mount your internal drive inside your computer.
YOUR OBJECTIVE: A securely positioned drive whose connectors are
within easy reach of the various cables that must
attach to it.
YOUR METHOD: Identify the drive bay where you will mount your
drive. Remove bay cover. If necessary, use
mounting rails to install drive in bay.
Your PC probably looks something like this:
You can mount your drive in any available bay. You must remove the small panel that
covers the bay that you want to use. Typically, this is done after you have removed
your computer’s cover. The panel can then be popped out by pressing outward lightly
(in some older cases you may have to remove screws that hold the panel in place).
You now need to determine if you must install mounting rails on the sides of your
drive. To do so, insert the drive into the open bay. If the drive fits tightly with little or
no clearance on either side of the drive, you will not have to use mounting rails. The
drive can be mounted directly into your computer.
Caution: Donot mountyour drive inyour computerusingscrews otherthan those
supplied by Plextor. You may damage the drive if you insert screws that
are too long.

CHAPTER 8 ---- Hardware Installation
26 ULTRAPLEX OPERATION MANUAL

If you must use mounting rails, install them as shown below:
There are four holes provided on each side of the drive. To mount an internal drive
in most computers, the rails should be fastened to the lower pair of holes. In some
instances you may need to fasten the rails to the upper set of holes.
Youwill findthateight screwsweresupplied with yourdrive: four chromescrews and
four black screws. Select which screws to use based on which set of holes you use to
attach the mounting rails.
✓Use the chrome screws if you use the upper set of mounting
holes.
✓Use the black screws if you use the lower set of mounting holes.
Check the positioning of the rails by sliding the drive into the bay before you connect
any cables.
Check Your Jumper Settings
Once you have determined a) the correct set of holes to use to attach mounting rails,
or b) that you don’t have to use mounting rails, you are almost ready to finish your
drive’s installation. Before doing so, however, check your jumper settings one
last time.
If you do not have any SCSI peripherals (e.g., hard disk, scanner, printer, etc.) in your
systemother than your CD-ROMdrive,you should not changethe jumpers from their
factory setting.
If you do have other SCSI peripherals as part of your computer system, you may need
to change the settings of the SCSI ID and Terminator. See Chapters 6 and 7 for
information on how to change these settings.
Be sure not to mistake the inner and outer face of
the rail when attaching. The smooth side of the rail
faces away from the drive’s chassis.
CHAPTER 8 ---- Hardware Installation
ULTRAPLEX OPERATION MANUAL 27

Cable Connections
You must make a minimum of two cable connections to your CD-ROM drive. A third
cableconnectionneed bemade onlyifyou areusing asoundboardinyourcomputer.
The two cable connections that you must make are:
1) SCSI cable
2) power cable
The SCSI cable you will need is a standard 50-pin flat ribbon cable. If you already
have one other SCSI peripheral (such as a hard disk), and your existing cable has only
two connectors, remove the cable and replace it with a cable with additional
connectors.Connect the SCSI host adapter to aconnectionon either end of the cable.
Connectthetwo peripheralsto theother twoconnectors(oneatthe middleconnector
and one at the end of the cable). Refer to Chapter 7 of this manual for setting the
termination of the devices.
CAUTION: It is easy to accidentally plug your SCSI ribbon cable upside down into
bothyourdriveandSCSIinterfaceboard.Accordingly,besureyoumatch
the red stripe along one side of the SCSI cable to pin 1 on the interface
boardandpin1onthedrive(asshownonthenextpage).Eachconnector
on the ribbon cable has a ‘‘key’’ in the middle. This key should fit into a
slotinthemiddleofeachconnectoroftheinterfaceboard,yourUltraPleX
CD-ROM drive, and any other SCSI peripherals. Additionally, ensure
there are no kinks or knicks in the cable and that the length does not
exceed 1.5 meters.
Double-check your work; you must ensure the side of the SCSI cable with
the red stripe is matched to pin 1 on the interface board and on the drive.

28 ULTRAPLEX OPERATION MANUAL

The easiest way to install your SCSI cable is to plug it into the SCSI connector on the
rear panel of the drive before you insert the drive into your computer. Then you can
thread the cable through the front of the open bay you plan to use and back toward
the SCSI interface board. Connect the cable to your SCSI interface board and finish
mounting your drive in the proper position. The drive should slide smoothly into the
bay.Ifitdoesnot,checkforobstructionsinthebayandensurethesiderails(ifneeded)
are attached properly.
You now need to make the power connection. In most computers you will find
additional power connectors that are ready for use. Check the cable running from
your power supply to your hard disk and see if it has extra connectors on it. If so, you
can plug one of these into the power connector found on the rear panel of the
CD-ROM drive.
If you do not find any additional connectors available (either because they were not
supplied, or they are all in use), you will have to buy a ‘‘splitter’’ or a ‘‘Y-connector.’’
These can also be found at most computer stores. If you are in a hurry to get started,
you can probably unplug the power connector from your 5.25" floppy drive (if you

haveone) and plugit into yourCD-ROMdrive. You willbe able touseyour CD-ROM
drive until you have the opportunity to buy a ‘‘splitter’’ or ‘‘Y-connector.’’ (Of course,
you will lose the use of your 5.25" drive until you buy a splitter/Y-connector.)
If your computer has only a 3.5" floppy disk drive, you may find that you do not have
a power connector that is the correct size to plug into your CD-ROM drive. Once
again, you can turn to your local computer store for a splitter to solve this problem,
or you might find an adapter that converts the smaller-sized power plug found on a
3.5" drive to the size required for your CD-ROM drive.
A third cable, an audio cable, must be used if there is a soundboard in your system.
This cable runs from the four-pin audio output connector on the rear panel of your
drive to your soundboard. See page 34 for more information about audio cables.
Installation of your internal drive is now complete. Skip to page 33.
External Drive Installation
YOUR TASK: Connect cables from your external drive to your PC
or Mac. Check to see if switch, dial, and terminator
settings need to be adjusted.
YOUR OBJECTIVE: A well-functioning drive that does not conflict with
any other peripherals in your computer system.
YOUR METHOD: Follow directions below for making cable
connections. Review your current computer setup
to see if the potential for conflicts exists. If so, make
necessary switch, dial, and/or terminator changes.
If you are installing a single UltraPleX external drive, and you have no other SCSI
peripherals attached to your system, you should leave the switches, dial, and
terminatorfoundon therearpanel ofyourdriveattheir factorysettings.If youdohave
additional SCSI peripherals (e.g., scanner, printer) attached to your computer, you
may need to change your switch, dial, and terminator settings. See Chapters 6 and 7
for information on how to change these settings.
If you are installing a single UltraPleX external drive, connect it as shown on the next

NOTE: The following section is only for those installing a soundboard in their
PC. If you are not using a soundboard, skip to Chapter 9.
Soundboard Installation
YOUR TASK: Install a soundboard in your PC.
YOUR OBJECTIVE: Make sure that the soundboard works properly with
your CD-ROM drive.
YOUR METHOD: Follow the instructions for installation that came
with your soundboard. Follow the instructions
given below to connect the soundboard to your
CD-ROM drive.
From Plextor’s perspective, soundboards fall into one of three major categories:
1) Soundboards that have no CD-ROM drive interface (e.g., ATI Stereo F/X,
Logitech Sound Man 16, Turtle Beach Multi-Sound). Most soundboards fall
into this category.
2) Soundboards that have a proprietary or IDE CD-ROM drive interface built
onto the board (e.g., Creative Labs Sound Blaster, Orchid Sound Producer
Pro,Wearnes Tech BeethovenADSP-16). Typically, the onlydrives that can
be attached are mediocre performers that sell for a low price.
3) Soundboards that have a SCSI CD-ROM drive interface built onto the board
(e.g., Media Vision Spectrum 16, Diamond SonicSound, Prometheus Aria
16SE). Any SCSI CD-ROM drive can be attached to this type of soundboard
and should work if the proper device drivers are used. However, the SCSI
interface will not be high performance.
If you own a soundboard that falls into category #1 or #2 and want to use it with your
UltraPleXdrive, you must alsobuya separate SCSI interfaceboard. You should follow
the directions starting on page 22 regarding the installation of a SCSI interface board.
Then, check the diagrams given on page 34 to see how you should connect your
audio cable.
If you own a soundboard from category #3, you do not have to buy a separate SCSI
interface board. However, most soundboards with a built-in SCSI interface do not
perform well because they use only an 8-bit SCSI interface. (This is true even if you
buy a ‘‘16-bit’’ soundboard. The ‘‘16-bit’’ refers to the audio channel, not necessarily
the SCSI data channel. The soundboard may have only an 8-bit SCSI interface on it.)
Plextor recommends the use of a separate SCSI interface.
CHAPTER 8 ---- Hardware Installation
ULTRAPLEX OPERATION MANUAL 33

Whichever category your soundboard falls into, you will find that the best source of
information about installing the soundboard in your computer is your soundboard’s
manual. Once you have successfully installed your soundboard in your computer,
you can continue to the next section, which describes the different cable connections
that need to be made.
Audio Cables
Weinclude two audio cables with your internalCD-ROMdrive SCSI card kit and one
cable with your external drive SCSI card kit. One cable delivered with your internal
drive is MPC compliant, and the other has connectors designed for use with Sound
Blaster sound cards. The cable delivered with your external drive has two RCA-type
color-coded connectors at one end, which connect to your drive, and a single stereo
mini-jackattheotherend,whichplugsintotheline-inreceptacleonyoursoundboard
(at the back of your computer).
If you purchased an internal drive SCSI card kit and you have a sound card other than
Sound Blaster that is not MPC compliant, you will have to purchase a different audio
cable from a computer supply store. We can help by recommending several vendors
(see listing, p. 62) who offer audio cables, and can get them to you quickly at a
reasonable price. Call our Technical Support Department directly at 800-886-3935.
Please see next page for diagrams illustrating the cable connections.

Software Installation
YOUR TASK: Install software onto your computer system to
enable the CD-ROM drive to operate optimally
within your specific operating system.
YOUR OBJECTIVE: Enable your CD-ROM drive to communicate with
the rest of your computer system.
YOUR METHOD: Identify your operating system and refer to the
section of this chapter, or the Plextor Manager
manual, that pertains to your operating system.
A device driver is a software program that allows your computer to interact with
yourCD-ROM drive. If youdo not use adevicedriver, or youusean outdated version
of the required device driver, you will not be able to operate your CD-ROM drive.
The lack of a device driver, or the use of an improper version of a device driver, are
the most common source of business for Plextor’s Technical Support Department.

OS/2
Installation Procedure
To install OS/2 from your OS/2 CD-ROM disc, you first need to verify that your SCSI
interface board is supported by OS/2. Check your OS/2 manual and the README file
on the floppy disk that comes with the OS/2 CD-ROM for information on which SCSI
interface boards OS/2 supports.
If your SCSI interface board is on OS/2’s list of supported hardware, you can follow
the installation instructions provided by IBM.
However, if your SCSI interface board is not on OS/2’s list of supported hardware,
youmustcontactthemanufacturerofyourboardandrequestanOS/2softwaredevice
driver. (See listing of key contacts on page 62.)
The OS/2 device driver files that you need from your SCSI interface board’s manufac-
turer end with an ‘‘.ADD’’ extension. They need to be copied into the CONFIG.SYS
file on the OS/2 installation floppy disk. Your SCSI interface board manufacturer will
provide you with specific instructions.
Adding CD-ROM Support After OS/2 Has Already Been Installed
1) You first need to verify that your SCSI interface board is supported by OS/2.
Check your OS/2 manual, and the README file on the floppy disk that
comes with the OS/2 CD-ROM, for information on which SCSI interface
boards OS/2 supports. If your SCSI interface board is included on the list of
supported hardware, you can skip to step #3.
2) If your SCSI interface board is not on OS/2’s list of supported hardware, you
must contact the manufacturer of your board and request an OS/2 software
device driver. (See listing of contacts on page 62.)
3) Once you have confirmed that your SCSI interface board is supported by
OS/2, or you have obtained the necessary device driver files, run OS/2’s
Selective Install program to set up your SCSI interface board and CD-ROM
drive. In the ‘‘SCSI Host’’ field, select your board. (If your board was already
installedandrunning, yourSCSI interfaceboard shouldalready beselected,
andthereisnoneedforyoutochangethisentry.)TheCD-ROMdriveshould
automatically be detected. In the event that the CD-ROM drive is not seen,
please go to the ‘‘CD-ROM Drive’’ field, select ‘‘Texel/Plextor 3024/5024,
3028/5028, 4PleX’’. Then, select ‘‘Install’’ and insert the OS/2 floppy disks
when requested. After rebooting, your CD-ROM drive should appear in the
‘‘Drives’’ folder.

OS/2 Troubleshooting Tip
IfyouhavedifficultygettingOS/2torecognizeyourCD-ROMdriveandSCSIinterface
board, you should first verify that all of your hardware is operating properly.
This is best done by installing DOS. If your system also does not work under DOS,
you probably have a hardware problem that needs to be resolved before you can go
any further. Refer to the Troubleshooting guide in Chapter 12. If your system works
under DOS (but not OS/2) review your device driver installation and verify that the
SCSI interface board driver and CD-ROM support (see step #3 on page 37) is loaded
correctly.
Windows NT 4.0 (and Below)
Installation Procedure
To install Windows NT from your NT CD-ROM disc, you first need to verify that your
SCSI interface board is supported by NT. Check your NT manual for information on
which SCSI interface boards NT supports.
If your SCSI interface board is on NT’s list of supported hardware, you can follow the
installation instructions provided by Microsoft.
If your SCSI interface board is not on NT’s list of supported hardware, however, you
must contact your board’s manufacturer and request an NT software device driver
(see listing of key contacts on page 62).
The files you obtain need to be added to the NT installation floppy disk(s) that came
with your NT CD-ROM disc. Your SCSI interface board manufacturer will provide
you with specific installation instructions.
Adding CD-ROM Support After NT Has Already Been Installed
1) You first need to verify that your SCSI interface board is supported by NT.
Check your NT manual for information on which SCSI interface boards NT
supports. If your SCSI interface board is included on the list of supported
hardware, skip to #3.
CHAPTER 9 ---- Software Installation
38 ULTRAPLEX OPERATION MANUAL

2) If your SCSI interface board is not on NT’s list of supported hardware, you
must contact your board’s manufacturer and request an NT software device
driver (see listing of key contacts on page 62).
3) RunNT’s Setup program toadd support for yourSCSI interface board. Select
‘‘Add/Remove SCSI Adapters . . .’’ from the menu. Choose your SCSI inter-
face board from the list or, alternately, add the driver you obtained from
your SCSI interface board manufacturer.
4) Shut down your system and connect your UltraPleX to the SCSI controller.
5) Power ON your computer and your UltraPleX drive should now be visible
to the system.
Windows NT Troubleshooting Tip
If you have difficulty getting NT to recognize your CD-ROM drive and SCSI interface
board, you should first verify that all of your hardware is operating properly.
This is best done by installing DOS. If your system also does not work under DOS,
you probably have a hardware problem that needs to be resolved before you can go
any further. If your system works under DOS, but not NT, review your device driver
installation and verify that the SCSI interface board device driver and CD-ROM
support (step #4, above) are loaded correctly.
