This is a digital audio output connector or Video CD output connector.
You can connect this to the digital audio system or Video CD Board.
2Analog Audio Output Connector
The Audio Output Connector connects to a sound card.
The supplied audio cable is a SoundBlaster®type cable. If you have a different
sound card, you will need to contact the sound card manufacturer to obtain the
proper cable for that card. This cable is necessary to play audio CDs.

These three jumpers are used to set the DVD-ROM Drive to either a Master,
Slave, or CSEL drive.
Refer to section HARDWARE INSTALLATION.

HARDWARE INSTALLATION
This section describes how to install your DVD-ROM drive into your computer.
Note: If you are not comfortable about opening your PC and attempting the DVD-ROM
drive installation, many local computer shops can perform this service for a
reasonable cost.
This installation assumes you have a PC with an available connector on an IDE
interface cable. If your PC has an IDE hard drive, there is usually an available connector
in the middle of the same cable that attaches from the motherboard (or controller card)
IDE connector to the hard drive. Some PC’s have 2 IDE ports on the motherboard or
controller card, and you may need to purchase on IDE cable to use an unused IDE port.
If you do not have an available IDE connector or IDE port, you may need to purchase
an IDE controller card to install this DVD-ROM drive. Inspecting and knowing your PC
system will make your installation easier and less time consuming.
A final note before installation: The cable connecting to your floppy disk drive is not an
IDE cable. Do not attempt to attach the DVD-ROM drive to this cable.
If the DVD-ROM drive is to be connected to the same cable as the hard drive, be sure
that the hard drive is set as master. Hard drives can be set as single, master, or slave.
Check your hard drive owner’s manual or contact the hard drive manufacturer for
correct jumper settings.
SETTING MASTER / SLAVE JUMPER
* You will see three pairs of pins and a jumper (cap) at the back of the DVD-ROM drive.
This jumper is used to set the DVD-ROM Drive as a CSEL, MASTER, or SLAVE device
in your PC. Examples of how the jumper can be placed are shown in Figure 3 below.
* Move the jumper (clip on one pair of pins) from its default factory position (SLAVE) to
CSEL or MASTER as needed (see the following description for the setup that matches
your system), using the above diagram to place the jumper.
WARNING:
To protect the DVD-ROM Drive, your computer, and peripheral devices from damage,
turn off their power before installing the drive.

WHEN USING A PRIMARY IDE CONTROLLER
Most PCs provide one IDE cable to support two devices (one for hard disk, the other for a
second hard disk or a DVD-ROM drive). This IDE cable originates either on the motherboard
or on a controller card. This controller is termed the primary IDE controller, and the hard disk
attached that contains the operating system for boot-up is set up as the Primary Master. Your
DVD-ROM drive should be set to the Slave mode.

WHEN USING A SECONDARY CONTROLLER
* If your PC has an additional IDE controller on the motherboard or in a system slot, each
IDE device connected to the secondary IDE controller must also be set to the Master or
Slave mode. If you are connecting your DVD-ROM drive to a secondary IDE port, and it
is the 1st device you are connecting to it, then set the DVD-ROM jumper to the Master
position. If it is the 2nd device, set the DVD-ROM jumper to the Slave position.
* Depending on the IDE card and whether the DVD-ROM drive is a master or slave
unit, the diagram below represents the different ways in which the DVD-ROM may
be configured in your PC. The table below the diagram shows the possible Jumper
placements that would correspond to each of the different configurations shown.

MOUNTING THE DVD-ROM DRIVE
Step 1. Turn off and unplug your
computer and all peripheral
devices attached to it.
Step 2. Remove the cover from your
computer.
Step 3. Remove the front panel from an
unused half-height slot.
Step 4. Slide the DVD-ROM drive into
the half-height slot, and secure
the drive in place with screws.
Note: If there is too much space between
the sides of the drive and the drive
bay, you may need to install spacer
brackets, available at your local
computer store.
Step 5. Push the power supply cable
connector firmly into the power in
connector.

CONNECTING AN AUDIO CABLE
Step 6. Connect the 40-pin IDE Cable to
the back of the DVD-ROM Drive.
Please make sure that the red
edge of the IDE Cable is
connected to Pin 1 on the DVD-
ROM Drive.
If you want to connect audio equipment or
a sound card to the DVD-ROM drive, use
an audio cable to connect the drive to the
sound device.
Note: This CD-ROM Drive can be used
vertically.
•To use the drive vertically, open the
drawer and put a disc on to the 2 disc
hooks. Use only standard 12cm discs.
•Do not touch the unlabeled side of the
disc.
