The RATOC U2SCX USB 2.0 to Ultra SCSI Converter is one of the few commercially produced adapters that allows legacy SCSI devices to be connected directly to a USB-equipped computer. It was especially popular for connecting vintage scanners, MO drives, Zip/Jaz drives, CD-ROMs, and SCSI hard drives to modern PCs and Macs.

Features

• Converts Ultra SCSI (50-pin HD) devices to USB
• Supports both USB 2.0 High-Speed and USB 1.1 ports
• Hot-pluggable (connect/disconnect without rebooting)
• Works with:
  • SCSI hard drives
  • MO drives
  • Zip and Jaz drives
  • CD-ROM and CD-R/RW drives
  • DVD-RAM/ROM/RW drives
  • Tape drives
  • Flatbed and film scanners
• Two operating modes:
  • USB Mass Storage Mode for storage devices
  • SCSI Emulation Mode for scanners and specialized SCSI peripherals
• Can support up to 7 SCSI devices in a daisy chain under Windows when using the RATOC driver.

Originally supported:

• Windows 98SE
• Windows Me
• Windows 2000
• Windows XP
• Windows Server 2003
• Mac OS 9.2.1+
• Mac OS X 10.2.1+
• Optional drivers were later offered for Windows Vista and Windows 7.

Important Limitations

• The adapter relies on SCSI Termination Power (TERMPWR) from the attached device. Some older devices do not provide enough power, requiring an external 5V adapter.
• Under macOS, only one SCSI device can be attached at a time; daisy-chaining is not supported.
• Some very old or unusual SCSI devices may not be recognized, and specialized software such as VueScan is often needed for vintage scanners.

Connector Type

The U2SCX plugs directly into a SCSI device with a:

If your device uses a different connector (Centronics 50, DB25, or 68-pin HD), you'll need an appropriate SCSI adapter cable or converter.

If you tell me which SCSI device you want to connect (scanner, hard drive, MO drive, tape drive, LS-120/240 setup, etc.), I can tell you exactly what additional cables or adapters are required.
