Overview
The GL711FW is a high-performance 1394 to ATA/ATAPI native bridge with an embedded SBP-2 target solution. It supports a solution for link/transaction layer controller conforming to the IEEE Std 1394 (IEEE 1394-1995 and IEEE 1394.a) up to 400Mbps transfer rate. Through the SBP-2 port driver, supported by Microsoft Windows 2000 and Windows 98 SE, Windows ME, SCSI class drivers can use SBP-2 to communicate with IEEE 1394 device using the SCSI command set.
