WEEE Statement English
In order to cope with the increasing waste electrical and electronic equipment, reduce the use of landfill and
incinerator, and prevent the harmful matter of waste equipment from entering the environment, the European
Union (EU) has set the Directive on Waste Electrical and Electronic Equipment (WEEE) asking manufacturers
to collect, recycle and treat waste electrical and electronic equipment properly. Member nations already
established their free of charge recycle systems of WEEE before August 13, 2005. Accordingly, ACARD has
to be responsible for recycling all products exported to Germany. You can return your ACARD product that
needs recycling to a local collector.
WEEE Erklärung German
Mit dem Ziel die steigende Menge elektrischer und elektronischer Altgeräte zu bewältigen ohne hierzu
unnötig Mülldeponien und Verbrennungsanlagen zu belasten und um die Verschmutzung der Umwelt durch
freiwerdende Stoffe aus den Altgeräten zu vermeiden, hat die Europäische Union (EU) die Richtlinie über
Elektro-und Elektronik-Altgeräte erlassen. Die Richtlinie verpflichtet Hersteller, elektrische und elektronische
Altgeräte umweltgerecht einzusammeln, zu recyceln und zu entsorgen. Die Mitgliedsstaaten der EU haben
bereits ihre kostenfreien Recyclesysteme konform der WEEE vor dem 13. August 2005 eingerichtet.
Entsprechend der Richtlinie ist ACARD verantwortlich für die umweltgerechte Entsorgung aller nach
Deutschland exportierten ACARD Produkte. Sie können Ihr zu entsorgendes ACARD Produkt zu Ihrer
örtlichen Sammelstelle bringen.
AEEA verklaringDutch
Met het doel de stijgende hoeveelheid afgedankte elektrische en elektronische apparatuur te beheersen
zonder hiervoor onnodig stortplaatsen en verbrandingsovens te belasten en om de vervuiling van het milieu
door vrijkomende stoffen uit de afgedankte apparatuur te voorkomen, heeft de Europese Unie (EU) de richtlijn
betreffende afgedankte elektrische en elektronische apparatuur besloten. Deze richtlijn verplicht fabrikanten
afgedankte elektrische en elektronische apparatuur in te zamelen, te recyclen en te verwijderen. De lidstaten
van de EU hebben reeds de kosteloze recyclesystemen volgens de AEEA vóór de 13 augustus 2005
ingericht. Conform de richtlijn is ACARD verantwoordelijk voor de verwijdering van alle naar Nederland
geëxporteerde ACARD producten. U kunt uw afgedankt ACARD product naar uw locale inzamelplaats

LVD SCSIDE Bridge Manual
SCSIDE®is a revolutionary new technology developed by ACARD Technology
Corp. It can not only transform IDE data into SCSI type, but also save the
expenditures. Through this technology any cheap IDE device can have high-
performance SCSI applications. The following examples are merely a little portion
of SCSIDE®applications.
1. To transform an IDE hard disk into an external SCSI one for notebook and desktop
PC users to back up data.
2. To transform an IDE CD-ROM or CD-R/RW into a SCSI one. It is an unprecedented
technology.
3. To transform your favorite IDE DVD-ROM, DVD-RAM/R, DVD−R/RW or
DVD+R/RW into an LVD SCSI one.
4. To daisy chain multiple SCSIDE®DVD-ROMs to create a DVD-ROM server.
5. To transform a DMA 66/100/133 hard disk of 5400rpm or 7200rpm into a SCSI
one for PC workstations, servers and even Unix workstations and servers.
The basic structure of SCSIDE®is a “System On Chip” which highly integrates
multiple CPUs. This SOC design is resulting from ACARD’s years of experiences
in the design of IDE, SCSI and RISC CPU chips. The block diagram on the next
page shows that SOC has multiple CPUs. Its ROM, RAM, DMA controllers and
external ROM interface can be used as the firmware upgrade of flash ROM. In
ACARD’s technologies there is a perfect firmware design as well. It makes the
transformation of IDE to SCSI really “plug and play”. The firmware has been tested
on many kinds of IDE DMA66 /100/133 HDDs, CD-ROMs and DVD-ROMs. No
matter your IDE device is an ATA hard disk or DVD-ROM, you all can plug it and

enjoy the advantages of SCSI. With the intelligent firmware design, you don’t need
to install a driver into the operating system so as to use SCSIDE®products. In the
operating system it is just a SCSI device.
1.2 SCSIDE®Design
The objectives of SCSIDE®design are given as follows:
1. Reduce the expenses of SCSI by using a cheap IDE device.
2. Create applications like SCSI CD-ROM, high SCSI DVD-ROM, etc.
3. Apply ”plug and play” to the transformation of IDE device to SCSI one. It is not
necessary to install a driver.

sec in AEC-7726H/Q).
lThe on-board flash ROM is easy to update firmware.
1. AEC-7722 and AEC-7726H/Q have the following features:
Thank you for purchasing AEC-7722, AEC-7726H/Q, ARS-2100/2100Q, ARS-2120,
ARS-2000LFS or ARS-2000LHS SCSI-IDE Bridge. You must feel the bridge’s
attraction in the high-tech industries worldwide after using it. Through the SCSI-
IDE Bridge, you can turn a cheap IDE interface into a SCSI one. The on-board core
microcontroller developed by ACARD makes the bridge more flexible, more stable
in high level applications. AEC-7722 supports DVD drives. AEC-7726H/Q, ARS-
2100/2100Q, ARS-2120 and ARS-2000LFS support 3.5” IDE hard drives. ARS-
2000LHS supports 2.5” IDE notebook hard drives. All the devices are easily
connected to SCSI bus.

Chapter 3 Hardware Installation
Hardware installation includes two parts. The first part is the installation of SCSI
adapter like AEC-67160. The second part is the installation of AEC-7722 or AEC-
7726H/Q, etc. Yet, you have to set jumpers at first (see page 33-37).
Insert the PCI edge connector of SCSI adapter firmly into PCI slot so as to connect
other devices internally or externally.
If your old hard drive contains an OS, you had better partition and install the OS
again. In DOS and Windows it is all right without installing anew, but the different
commands on the SCSI adapter and IDE controller will result in read/write errors.
Therefore, after installation regard the IDE hard drive as a brand-new one.
3.1 InstallingAEC-67160
Refer to the manual of AEC-67160 to install the driver before installing the SCSI
adapter. If the driver on the CD is not the newest version, you need to download it
from Internet onto a floppy, and then install it into your computer. The Web site of
ACARD is http://www.acard.com.

3.2 Compatibility
3.2.1 Supported DVD-ROMs
AEC-7722 is particularly designed for DVD drive. It has been tested, and perfectly
supports every major kind of DVD-ROM/DVD writer with different generation and
speed. It supports the following brands.
lAOPEN lTEAC
lASUS lLG
lLiteon lHP
lPanasonic lNEC
lPioneer lPlextor
lRICOH lSANYO
lSony lMATSUSHITA
Through AEC-7722 an IDE DVD drive can be transformed into a SCSI one, but
most CD recording software still regards it as an IDE one . Thus the recording soft-
ware willsend 12-byteIDE commands. OnlyaspecialSCSIadapter such as AEC-
67160cansolvetheproblem.
3.2.2 Supported SCSI Adapters
3.2.3 Supported Recording Software
In order to make an IDE DVD writer work stably and normally after being trans-
formed into a SCSI one, it needs not only a SCSI adapter, but also fine recording
software like the following ones.
