Introduction
Congratulations on your purchase of Adaptec’s USBConnectTM 2000
adapter. The USBConnect 2000 adapter allows SCSI devices to plug
into the Universal Serial Bus (USB) port of your PC or MAC
computer.
The built-in SCSI controller in the USBConnect 2000 adapter allows
you to connect up to seven SCSI devices to your desktop or portable
PC or MAC. These devices include the Iomega Jaz drive, CD-ROM
drives, hard disk drives, Magneto-optical (MO) drives and most
scanners.
Overview
The USBConnect 2000 adapter is designed as an integrated adapter
and 50-pin high-density (SCSI 2) connector and is available as a
■USB-to-SCSI with a 50 pin Micro-D SCSI-2 type connector
Note: The USBConnect 2000 adapter is designed as a self-
powered device and as such receives it’s power from the ter-
mination power line of the attached SCSI devices. As a
result, all SCSI devices must supply termination power.
Some devices such as the Iomega Zip drive and some
scanners do not provide termination power and therefore
can only be used if they are attached to the SCSI chain with
another SCSI device that provides termination power.
