ASUS CRW-5232AS 13

Features

The ASUS CRW-5232AS is a CD-RW drive with 52X-write, 32X-rewrite, and
52X-read capabilities. The drive complies with the AT Attachment Packet Interface
(ATAPI) specification and comes equipped with the latest innovative technologies
in CD recording. Designed to be shorter than common internal CD-RW drives, the
ASUS CRW-5232AS is an ideal optical drive solution for mini-PC systems.

The ASUS CRW-5232AS employs the ASUS FlextraSpeed™ and FlextraLink™
technologies to ensure an efficient and reliable data transfer and storage.

FlextraSpeed™ increases accuracy and reliability when rewriting across a wide
range of disc media, while FlextraLink™ prevents buffer underrrun problems for
error-free recordings. The following sub-sections describe these technologies in
detail.

14 ASUS CRW-5232AS

FlextraSpeed™ Technology

The ASUS FlextraSpeed™ technology provides the optimum solution to ensure
quality recording when using discs that require flexible speeds. The CRW-5232AS
drive employs this technology that allows automatic recording speed adjustment
based on the recording media.

In addition to the fact that there are low and high quality recording media, various
other factors such as dye layer, temperature, humidity, dust, fingerprints, etc.,
affect the recording characteristics of CD-R and CD-RW discs. Due to these
factors, some discs may not be able to stand the high-speed capabilities of the
latest CD-RW drives. The FlextraSpeed™ technology solves this problem by
automatic assessment of the disc quality and recording capability. The recording
speed is based on these factors. If you use a high quality recording disc, you can
maximize the recording capability of the drive and get the best quality output. If you
use a low quality disc, the drive speed adjusts to the level that is most appropriate
for the disc, still optimizing the disc recording capability.

ASUS CRW-5232AS 15

The FlextraSpeed™ technology also helps maintain the CD-RW drive because of
the controlled motor rotation speeds and reduced noise caused by spindle air, thus
prolonging the drive motor’s life and ensuring high-quality recording.

FlextraLink™ Technology

The ASUS FlextraLink™ technology provides a seamless combination of flexibility and
ultra-reliable recording quality.

FlextraLink™ incorporates a flexible strategy that prevents buffer underrun problems
caused by an empty data buffer. This CD-RW drive technology allows continuous
monitoring of the data buffer status during the write process. Once the available data
drops to approximately 1% of the total buffer capacity, the drive stops recording and
marks the last write position. When new data is received from the host, it is loaded to
the data buffer, and the laser is repositioned to link the new data with the data already
written. FlextraLink™ uses minimal system resources so that your PC remains fully
operational throughout the writing process, and available for other applications.

The diagram on the following page shows the advantage of the FlextraLink™
recording technology.

Double Dynamic Suspension System (DDSS II)

The DDSS II is an enhanced follow up to the DDSS anti-vibration system
developed by ASUS. The DDSS technology is designed to reduce the vibration
generated from spindle rotation of over 8900 rpm of CD-RW drives. The DDSS II
improves this feature by handling up to over 10,000 rpm of the new CD-RW drives.
In addition, the DDSS II stabilizes the pick-up head of the drive in both horizontal
and vertical directions, making tracking and focusing even more precise.

Like the DDSS, the DDSS II vibration absoption structure contains a “dynamic
mass” that can absorb the vibration caused by high revolution of spindle motor.
However, the DDSS II moves the dynamic mass to be suspended to the chassis,
thus providing more stability and accuracy when accessing data from the disc.

The diagram on the following page illustrates the DDSS/DDSS II design structure.

DDSS / DDSS II Design Structure

ASUS CRW-5232AS 19

Constant Angular Velocity (CAV) Recording Technology

The CRW-5232AS drive employs the Constant Angular Velocity (CAV) recording
method. With CAV recording, the drive spindle motor rotates the disc at the same
speed regardless of the radial position of the pickup head. This means that there is
a higher transfer rate when writing data to the outer tracks of the disc than to the
inner tracks, as the head traverses a longer linear path on the outer than the inner
part of the disc.

Although the transfer rates vary, and may not be at maximum, depending on the
part of the disc being written to, the CAV method allows faster recording speed
because the rotation speed does not have to change when the head writes data to
different areas of the disc. This is primarily advantageous for computer
applications.

your computer supports four IDE devices, this mode sets your
CRW-5232AS drive as either Primary or Secondary Slave.

Cable Select Mode

Cover the two pins labeled CS if your computer supports a
Cable Select (CSEL) signal. You need an exclusive interface
cable for this mode. Refer to your computer manual for details.

28 ASUS CRW-5232AS

Installing the CRW-5232AS drive

Follow these steps to install the drive into the computer chassis.

Refer to your computer manual for specific instructions on opening the chassis
and installing drives.

1. Remove the cover of an
empty 5.25-inch drive bay.

ASUS CRW-5232AS 29

2. Carefully insert the drive into
the bay and push it inward
until it is flushed to the chassis
front panel. The holes on the
sides of the drive should align
with the holes on the drive
bay.

30 ASUS CRW-5232AS

3. Secure the drive with
screws that came with
the drive package. Use
two screws on each side
of the drive.

Depending on the space on your chassis, you may need to connect the drive
cables before securing the drive into the chassis. For cable connections,
proceed to the following section, “Connecting the Drive Cables.”

ASUS CRW-5232AS 31

Connecting the drive cables

1. Connect the power
cable plug to the
power connector on
the rear panel.

2. Connect the 40-pin
IDE cable plug to the

4-pin Audio Cable

IDE connector,
matching the red pin
stripe on the cable with Pin 1 on the connector.

3. If your computer has a sound card or an onboard audio feature, connect an
audio interface cable to the 4-pin analog audio connector on the rear of the
drive. Connect the other end of the audio cable to the connector on the sound
card or on the 4-pin CD connector on the motherboard.

All the cable plugs are slotted so that they fit in only one orientation. If a plug does not
fit in completely , try reversing it. DO NOT use too much force when fitting the cable
plugs. Replace the computer cover according to your computer manual.
