<strong>Overview</strong><br />
<strong>Addonics</strong> <strong>ATAPI</strong> <strong>to</strong> <strong>SCSI</strong> <strong>Converter</strong> <strong>Board</strong><br />
(Model: ADAEC7722)<br />
Thank you for purchasing the <strong>Addonics</strong> <strong>ATAPI</strong> <strong>to</strong> <strong>SCSI</strong> converter, model ADAEC7722. With this converter, you can use any standard<br />
<strong>ATAPI</strong> devices like a standard <strong>SCSI</strong> device. Thus many devices that are available only in <strong>ATAPI</strong> interface such as CDRW, DVD-R/RW,<br />
ZIP drive, MO drives and so can now be installed in<strong>to</strong> computers that have <strong>SCSI</strong> controller. Once installed, all application software works<br />
transparently. You can burn CD on CDRW, play DVD movie with a DVD ROM. The converter supports <strong>SCSI</strong> performance up <strong>to</strong> LVD160<br />
standard, thus ensuring that you will get the maximum performance from any <strong>ATAPI</strong> device.<br />
<strong>Features</strong><br />
• Built-in RISC CPU, <strong>SCSI</strong>, IDE controllers and interfaces on the chip.<br />
• Maximum data transfer - 80Mb/sec.<br />
• Full support of <strong>SCSI</strong> target features.<br />
• Programmable IDE access modes, including PIO mode 0,1,2,3,4.<br />
• Upgradeable firmware.<br />

Hardware Installation<br />
Internal Power Connection<br />
There are two kinds of internal power connec<strong>to</strong>rs providing power <strong>to</strong> the <strong>ATAPI</strong> device and AD-7722 circuit board. The large connec<strong>to</strong>r is<br />
for most <strong>ATAPI</strong> devices while the small one is for AD-7722. For correct connection see picture below:<br />
Cable Connection<br />
Before connecting AD-7722 <strong>to</strong> an <strong>ATAPI</strong> device, you should know the <strong>SCSI</strong> connec<strong>to</strong>r from the IDE one. On the circuit board the 68-pin<br />
connec<strong>to</strong>r is for <strong>SCSI</strong> adapter while the 40-pin one is for <strong>ATAPI</strong> devices. Please connect it <strong>to</strong> AD-7722. The steps are listed below:<br />
• Find out pin 1 of CN2 on AD-7722<br />
• Find out pin 1 of the connec<strong>to</strong>rs by pin <strong>to</strong> pin and connect them.<br />
• Find out the colored pin 1 of the connec<strong>to</strong>r on the other end of the <strong>SCSI</strong> cable and connect <strong>to</strong> CN1 of AD-7722. See below:<br />
Troubleshooting<br />
After installing AD-7722, if you find out that it does not work correctly. Try the following methods below:<br />
Check the <strong>SCSI</strong> host adapter<br />
Check if the adapter is firmly inserted in<strong>to</strong> PCI slot on the motherboard.<br />
Check all Connec<strong>to</strong>rs and Cables<br />
Check if the power connec<strong>to</strong>r, <strong>SCSI</strong> connec<strong>to</strong>r, <strong>ATAPI</strong> connec<strong>to</strong>r on the bridge, the power connec<strong>to</strong>r on the <strong>ATAPI</strong> device, and the cables<br />
are all properly connected. The cable is easily damaged due <strong>to</strong> folds. You may use a new cable. Be sure that the pins inside the connec<strong>to</strong>r are<br />
not bent and the two-colored pin 1 on both ends of the cable are corresponding <strong>to</strong> the pin 1 on CN1 of the bridge and the pin 1 on <strong>SCSI</strong><br />
adapter respectively.<br />
