Overview
This Installation Guide explains how to physically
install and configure Adaptec APA-348 MiniSCSI
™
Plus Parallel-to-SCSI host adapters. The MiniSCSI
Plus has been designed to provide simple, flexible
control of most SCSI devices. The adapter’s high-
speed operation is fully compatible with bidirec-
tional parallel ports, offering excellent performance
while remaining compatible with unidirectional
ports found on many older computers. Both SCSI
and parallel printer interfaces may be operated
simultaneously, with no performance degradation.
Hardware Requirements
■ The parallel port must be standard—i.e., have a
fully IBM
®
-compatible hardware design, includ-
ing all ground lines. For highest performance, the
computer’s parallel port must be capable of bidi-
rectional operation.
■ The SCSI device chain must be properly termi-
nated as per ANSI SCSI specifications.
■ The SCSI device(s) connected to the MiniSCSI
Plus must have the standard ANSI SCSI-
specification TERMPOWER implemented, since
the adapter draws its power from this line.
■ IBM or compatible AT
®
, PS/2
®
, or similar
computer.
■ A 100% IBM-compatible BIOS. Operation with an
incompatible BIOS may be possible but is not
guaranteed.
