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 FlextraSpeedand FlextraLink™  
technologies to ensure an efficient and reliable data transfer and storage.  
FlextraSpeedincreases accuracy and reliability when rewriting across a wide  
range of disc media, while FlextraLinkprevents buffer underrrun problems for  
error-free recordings. The following sub-sections describe these technologies in  
detail.  
14  
ASUS CRW-5232AS  
FlextraSpeed™ Technology  
The ASUS FlextraSpeedtechnology 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 FlextraSpeedtechnology 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 FlextraSpeedtechnology 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 motors life and ensuring high-quality recording.  
FlextraLinkTechnology  
The ASUS FlextraLinktechnology provides a seamless combination of flexibility and  
ultra-reliable recording quality.  
FlextraLinkincorporates 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. FlextraLinkuses 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  
massthat 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

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.

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

Connecting the drive cables  
1. Connect the power  
cable plug to the  
power connector on  
the rear panel.  
Power Cable  
IDE Cable  
2. Connect the 40-pin  
4-pin Audio Cable  
IDE cable plug to the  
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.
