Precautions
■Installation
• Avoid placing the drive in a location subject to:
–high humidity
–high temperature
–excessive dust
–mechanical vibration
–direct sunlight.
We recommend to use the drive in a horizontal position. Do not use
it in a tilted position.
■Operation
• Do not move the drive during operation. This may cause it to
malfunction during reading or writing.
• Avoid exposing the drive to sudden changes in temperature as
condensation may form on the lens inside the drive as a result.
Should the surrounding temperature suddenly rise while the drive
is on, wait at least one hour before you turn off the power.
Operating the drive immediately after a sudden increase in
temperature, may result in a malfunction during reading or
writing.
■Transportation
• Keep the original packing materials for future transport of the
drive.
• Remove the caddy before moving the drive and, if you take the
drive out of the computer, repack the drive as you received it.
Precautions

Example of System Setup
To use the CD-R device, the following components are required:
• Computer (IBM-PC/AT* compatible)
• SCSI-Host adapter
• SCSI-Interface cable (50 to 50 pin flat cable)
• Software (Device driver, utilities)
Example of System Setup

Installing the Drive Unit into the Computer
As you go through this section, you may wish to refer to your
computer’s manual for a more detailed description of how to install
internal drives.
Getting Started
• Prepare the necessary parts and tools that have not been supplied:
–Screwdriver
–four screws 3 mm in diameter (Screws must not extend more
than 4.0 mm into the side panels or the bottom plate.)
–two mounting rails if your computer has mounting tracks.
• Unplug the computer and disconnect the cables attached to the
back for your own safety. Do not turn on the power of the
computer before completing the entire installation process.
Setting the Jumpers
Set the jumpers on the rear panel of the drive unit in accordance
with the configuration of your computer system.
The jumpers are preset, as illustrated below, at the factory.
Installing the Drive Unit into the Computer

11
Remove the jumper to set to OFF, and install the jumper to set to ON.
The recommended jumper is AMP* Shunts (14227-1), JAE** Short
Socket (PS-2SH4-1) or equivalent.
The following table shows the function of each jumper.

Notes:
• The upper row of pins (without KEY position) is ground.
• ID SELECT, PREVENT/ALLOW, and TEST MODE are recog-
nized when the power supply is turned on or SCSI bus is reset.
• TEST MODE is used exclusively for the factory testing. Do not
set TEST MODE to ON. Doing so may cause an unexpected
result.

Caution:
Improper connection may damage the drive and void the warranty.
■Frame ground
When normally installed, the drive unit is not in contact with the
host computer directly and should be grounded. Connect the frame
ground tab to one of the host computer’s ground cables.
The frame ground cable recommended has aAMP 1-480435-0
housing and 170203-2 or 60711-1 contacts.

Host Adapter Installation
Connect the free end of the flat cable to the existing SCSI host
adapter card and install the host adapter in the computer by inserting
it securely in a system expansion slot. Refer to the operating
instructions of the host adapter for complete instructions on its
installation and the assignment of its switches.
Notes:
• The red edge of the flat cable must be closest to pin number 1 of
the interface card connector.
• The following illustration is a sample system configuration of the
Sony CDU948S CD-R drive installation with a SCSI card.

17Installing the Drive Unit into the Computer
Termination
• If the CD-R drive is connected at the end of the SCSI chain, keep
the drive terminator mounted at the drive.
• If the CD-R drive isn’t the last device at the SCSI bus, remove the
termination from the CD-R drive and make sure that the last
device at the SCSI bus has a proper termination installed.
• Be aware that the SCSI bus needs to be terminated at each end of
the SCSI bus cable.
Closing the Computer
1Replace the cover on the computer, being careful to reinstall all
screws that were removed.
2Replace the AC power cord and turn on your computer.

18 Installing the Software Driver
Installing the Software Driver
MSCDEX and the device driver for an ordinary SCSI CD-ROM
drive can be used when using the CDU948S as a SCSI CD-ROM
drive.
Use the device driver for a CD-R drive when using the CDU948S as
a recordable drive.
Be sure to install the device driver before operating the drive. Refer
to the manual supplied with the host adapter for instructions.
