This service manual provides a variety of service

information.

It contains the mechanical structure of the CD-RW

Drive and the electronic circuits in schematic form.

This CD-RW Drive was manufactured and

assembled under our strict quality control

standards and meets or exceeds industry

specifications and standards.

This CD-R/RW drive is an internal drive unit

designed for use with IBM PC, HP Vectra, or

compatible computer. It can write as much as 650

Mbytes of digital data into CD-R/RW disc, and can

read as much as 650 Mbytes of digital data stored

in a CD-ROM, CD-R and CD-RW disc.

The CED-8041B can easily meet the upcoming

MPC level 3 specification, and its Enhanced

Intelligent Device Electronics (E-IDE) and ATAPI

interface allows Plug and play integration in the

majority of today’s PCs without the need of an

additional interface card.

LOCATION OF CUSTOMER CONTROLS

1. Disc tray

This is the tray for the disc. Place the disc on the

ejected disc tray, then lightly push the tray (or

push the eject button) and the CD will be loaded.

NOTE: Don’t pull out or push in the disc tray

forcibly. This might cause damage to the loading

section of the drive.

2. Stop/Eject button

This button is pressed to open the CD tray.

This button works only when power is supplied to

the drive.

If an Audio CD is playing, pressing this button will

stop it, and pressing it again will open the tray.

3. Play/Skip button

When an Audio CD is in the disc drawer, pressing

this button will start playing Audio CDs from the

first track. If an Audio CD is playing, pressing this

button will skip to the next track.

4. Volume control

This is used to adjust the output volume of the

headphone jack. It can’t be used to adjust the

output volume for the audio output connectors on

the rear panel.

NOTE : Turn the volume down before turning on

the power. Sudden loud noises can damage your

hearing.

5. Headphone jack

This jack is for connecting headphones or mini-

speakers.

6. Drive activity indicators

Two colored LEDs are used to indicate the

operation of CD-R/RW Drive.

(1) Read

The orange color is displayed when the spindle

motor begins the Spin up operation: accessing

data, reading data, playing Audio, and up loading

tray.

(2) Write

The green color is flashed during disc writing

sessions.

1. Power Connector

Connects to the power supply (5-and 12-V DC) of

the host computer.

NOTE : Be careful to connect with the proper

polarity. Connecting the wrong way may damage

the system (and is not guaranteed). Usually this

connector can only be attached one-way.

2. IDE Interface Connector

Connect to the IDE (Integrated Device

Electronics) Interface using a 40-pin flat IDE

cable.

NOTE : Do not connect or disconnect the cable

when the power is on, as this could cause a short

circuit and damage the system. Always turn the

power OFF when connecting or disconnecting the

cable.

3. Jumper Connector

This jumper determines whether the drive is

configured as a master or slave. Changing the

master-slave configuration takes effect after

power-on reset.

4. Analog Audio Output Connector

Provides output to a sound card (analog signal).

Generally you need this to play a regular audio

CD.

5. Digital Audio Output Connector

Provides output to a sound card (digital Signal).
