AHA®-1540 Family
Connect any SCSI peripheral to any PC
Overview
For compatibility and ease of use, the
AHA-1540 family of ISA-to-Fast SCSI
host adapters is the ideal connection
for the widest choice in SCSI periph-
erals. Rigorously tested with more
than 300 systems and peripherals
from major manufacturers, these
adapters are the recognized standard
for SCSI compatibility.
Fully Windows®95 and SCSI Plug-
and-Play capable, the AHA-1540/1542
host adapters also set the standard
for ease of use. Configuration of the
adapters is automatic in any Plug-
and-Play system.
Key Benefits
Unmatched compatibility
The AHA-1540/1542 host adapters
connect up to seven SCSI devices to
any PC. Designed for computers with
standard ISA or EISA expansion slots,
they are compatible with virtually
any peripheral that complies with
the SCSI-2 standard. Plus, they
support all major operating systems
— Windows 95, Windows NT™,
DOS/Windows®, OS/2, UnixWare,
and NetWare.
Easy Plug-and-Play installation
Installation of the AHA-1540/1542
host adapters and SCSI devices is
quick and easy. Simply plug in the
board, and resources are automatically
assigned to ensure compatibility. Used
with SCSI Plug-and-Play peripherals
and cables, the AHA-1540 family
adapters quickly locate all connected
SCSI devices, instantly resolve any
SCSI resource conflicts, and properly
terminate the SCSI bus.
With Adaptec EZ-SCSI®software for
DOS and Windows, SCSI devices can
be installed in minutes following
simple menu-driven instructions.
Configuration settings can be quickly
modified from the keyboard using the
Adaptec SCSISelect®optimization utility.
Designed for multitasking
AHA-1540/1542 host adapters make
multitasking truly efficient. A multi-
threading, 10 MByte/sec Fast SCSI
interface to the ISA bus enables
seamless concurrent I/O operations.
And bus master DMA takes over
I/O processing and frees the CPU
for other tasks.
Quality and reliability
As with all Adaptec products, AHA-
1540/1542 host adapters have gone
through thousands of hours of rigorous
functional and environmental tests.
Trusted for quality and reliability,
Adaptec products are incorporated
into the products of virtually all major
system and peripheral manufacturers
around the world.
The complete kit
The AHA-1542 kit provides everything
necessary to add high-performance
Plug-and-Play SCSI devices to PCs.
It features the AHA-1542CP host
adapter board with a floppy drive
controller, complete user documenta-
tion, and Adaptec EZ-SCSI software
on CD. Adaptec EZ-SCSI software
applications enable users to create
their own CDs, play audio and view
photo CDs, perform tape backups,
benchmark SCSI peripheral devices,
and more.
