• IEEE 1394 (FireWire + iLink) and USB 2.0 Combo Host Interface
• Supports one IDE (ATA/ATAPI) device.
• Provides a switch which allow user to set the function for Read-only (Write Protect) or Read/Write.

The U2FW-IDE22 is a high performance USB 2.0 and 1394 combo bridge solution for connecting one ATA/ATAPI data storage devices, e.g. hard disk drives, CD-ROM, CD-R, CD-RW and DVD.

The USB interface of U2FW-IDE22 supports USB 1.1 or USB 2.0 specifications to allow connections to host computer via USB port at maximum data transfer rate 480 Mbps.

The 1394 interface of the U2FW-IDE22 is in compliant with IEEE Std 1394-1995 and IEEE P1394a specification supporting data transfer rate 100, 200 and 400 Mbps, and built-in SBP2 (Serial Bus Protocol 2) hardware engine to enhance sustained data transfer rate up to 40 MBytes/sec.

U2FW-IDE22 provides a switch which allow user to set the function for selecting ATA Read-only (Write Protect) or Read/Write.
