depends on the type and format of the target data. See the manual supplied
with your CD-ROM disc for instructions.
Example of System Setup
To use the CD-ROM drive unit, the following components are required:
●Computer (IBM PC, PC/XT, PC/AT, HP Vectra, or equivalent)
●Floppy disk drive
●IDE interface cable (40 to 40 pin flat cable)
●Software (Device driver, Utilities)

Precautions
■Installation
●Avoid placing the drive in a location subject to:
– high humidity
– high temperature
– excessive dust
– mechanical vibration
– direct sunlight
●The drive can be used in either a horizontal or vertical position.
●Do not force the power cable. It is keyed to protect the drive.
■Operation
●Do not move the drive when it is in use. Doing so may cause data error
and damage the optical pick-up.
●Avoid exposing the drive to sudden changes in temperature as
condensation may form on the lens inside the drive. Should the
surrounding temperature suddenly rise while the drive is turned on, stop
using the drive and leave the power on at least one hour before
operating it or turning it off. Operating the drive immediately after a
sudden increase in temperature may result in a malfunction.
■Transportation
●Close the disc drawer before moving the drive.
●Keep the original packing materials. When you need to ship the drive to
another location, repacking it in its original container will help you
transport it safely.

Pin 1

Setting the Jumpers
Set the jumpers on the rear of the drive in accordance with the
configuration of your computer system.
The jumpers are preset at the “MASTER” position as illustrated at the
factory.
Notes for configuration jumpers:
●Designation of the Drive Number is generally set by inserting a jumper
pin on either the MASTER or the SLAVE pin.
●When the CDU311 is daisy-chained with a Hard Disk Drive on an IDE
Card, set the Hard Disk Drive as MASTER and the CDU311 as
SLAVE.
●If the CDU311 is the only device connected to the IDE Card, set the
CDU311 as MASTER.
However, it should be noted that some personal computers may use CSEL
in lieu of the foresaid MASTER/SLAVE selection. In this case, remove the
existing jumpers from MASTER and SLAVE, and set a jumper on CSEL.
When the CSEL signal of the interface connector is set low, the drive is
designated as Drive 0. When the CSEL is set high, the drive is designated
as Drive 1.
Consult your PC manufacturer, IDE Card manufacturer or dealer for
further details.
Installing the Drive in Your Computer 11
Installing the Drive in Your Computer
This section provides an example of instruction for installing the CD-ROM
drive unit into your personal computer.
To connect the CDU311 directly to the PC’s IDE port, consult your PC
manufacturer for instruction.
Preparation You need the following parts and tools (these are not supplied with the
drive):
●A flat-blade screwdriver
●Four screws 3 mm in diameter and 6 mm in length.
●Two mounting rails if your computer has mounting tracks.
Unplug the computer and disconnect the cables attached to the back to
give yourself more room to work. Do not turn on the power of the
computer before completing the entire installation process.

Software Installation 19
Software Installation
The installation diskette enclosed in the package contains two software
items:
●Installer
●Device driver for MS-DOS/Windows 3.1
Note:
Both Microsoft CD-ROM Extensions (MSCDEX) or equivalent and Sony’s
Device Driver are required to run the CDU311 under the MS-DOS and
Windows 3.1 environment.
Therefore, prior to loading the installation diskette, make sure that the
MSCDEX is in the DOS directory of your hard disk drive (C:\DOS).
Although MSCDEX is included in the most up-to-date MS-DOS (ver. 6.2),
you may need to obtain the software from your PC dealer if you do not
have it.
The installer will automatically load MSCDEX via the AUTOEXEC.BAT
file and installs the Device Driver via the CONFIG.SYS file, if MSCDEX
is already in Drive C:\DOS.
Installing the Software Driver for DOS 6.X
Load the diskette into the floppy disk Drive A, and type:
>A:\INSTALL
and then, press the Enter key.
After installation, the following lines are added to CONFIG.SYS and
AUTOEXEC.BAT files.
in CONFIG.SYS:
Device=C:\DEV\ATAPI_CD.SYS /D:mscd000 /I:0
in AUTOEXEC.BAT:
C:\DOS\MSCDEX.EXE /D:mscd000 /M:12 /V
18 Software Installation

Note c)
Insert the disk labeled “MS-DOS Device Driver & Utilities” into the
floppy drive. Click on the Start button on the pop up menu and select the
Run option. When the dialog box appears, type
A:\INSTALL
and click on the OK button. The installation menu will appear.
Follow the instructions of the INSTALLATION utility. Reboot the
computer, run Windows 95, and verify the 8X CD-ROM drive setting by
clicking on the My Computer icon. The CD-ROM drive icon will appear.
■ Case 2: Using CD-ROM drive under MS-DOS by restarting computer in
MS-DOS mode.
If you want to use CD-ROM drive under MS-DOS by restarting computer
in MS-DOS mode, you should follow this installation procedure.
Insert the disk labeled “MS-DOS Device Driver & Utilities” into the
floppy drive. Execute INSTALL.EXE, then the installation menu will
appear. Follow the instructions of the INSTALLATION utility.
After that, use your DOS editor to edit the AUTOEXEC.BAT file by typing
C:\EDIT AUTOEXEC.BAT
and insert REM at the beginning of the following line as shown:
REM C:\WINDOWS\COMMAND\MSCDEX.EXE /D:mscd000 /M:12 /V
Save this modification by selecting File, Save, and Exit from the editor.
Then use your DOS editor to edit the DOSSTART.BAT file by typing
C:\EDIT C:\WINDOWS\DOSSTART.BAT
and add the following line:
C:\WINDOWS\COMMAND\MSCDEX.EXE /D:mscd000 /M:12 /V
20 Software Installation
Save this modification by selecting File, Save, and Exit from the editor.
Now restart your computer, run Windows 95, and choose restart computer
in MS-DOS mode. The CD-ROM drive is now available in MS-DOS
mode.
■ Case 3: Using CD-ROM drive under MS-DOS by previous MS-DOS mode or
command prompt mode only.
If you want to use CD-ROM drive under MS-DOS by Previous MS-DOS
mode or Command Prompt only mode, you should follow this installation
procedure.
Insert the disk labeled “MS-DOS Device Driver & Utilities” into the
floppy drive. Execute INSTALL.EXE, then the installation menu will
appear.
Follow the instructions of the INSTALLATION utility.
After restarting Previous MS-DOS mode or Command Prompt only mode,
the CD-ROM drive will now be available in these modes.
Software Installation 21

Note:
When the drive is set up in vertical position, use the disc locks to prevent
your disc from falling. See “How to Use the Disc Locks” on page 22 for
details.
4Gently push the drawer or press the eject button to close the drawer.
The drive may begin reading the Table of Contents (TOC) data when it
accepts the disc. The busy indicator lights up in amber while the drive
is reading the TOC.
For subsequent drive operations, follow the instructions provided with
the application software you are using.
Note:
The busy indicator stays lit in amber if:
– the disc is not properly placed on the loading tray
– a malfunction occurs.
In either case, eject the disc and place it in the loading tray again making
sure that it sits properly in the tray. If doing this does not solve the
problem and the busy indicator still remains lit in amber, consult your
dealer or qualified service personnel.
Caution: Do not forcibly close the disc drawer. Applying excessive force
may damage the loading mechanism. The tray’s mechanism is designed to
operate with a “feather touch”.
