FEATURES
• SCSI differential to single-ended
bus converter.
• Extends SCSI bus an additional
82 ft. (25 m).
• Asynchronous and synchronous
compatible.
• SCSI-1, SCSI-2, and SCSI-3 compatible.
• Single-ended to single-ended SCSI
bus extender.
• Does not occupy SCSI bus ID.
OVERVIEW
With the SCSI Differential Converter, you get two great
functions with one product. The SCSI Differential Converter
translates single-ended SCSI bus signals into differential
signals and vice versa. And it can be used as a single-ended
to single-ended bus extender system up to 121 feet
(36.9 meters). Just interconnect two units.
The SCSI Differential Converter is highly compatible.
It’s a popular choice for high-speed interconnection media
between micro, mini, and mainframe computers and high-
performance peripherals. And it’s compatible with most host
adapters and peripherals that conform to ANSI X3.131 and
X3T9.2 specifications.
Interface the SCSI Differential Converter with multiple host
computers to provide a high-speed, extended intercommuni-
cations link of standard SCSI bus interfaces. And remember
that peripherals with high-speed data throughput usually
need a differential interface to operate over longer cable
lengths. The SCSI Differential Converter gives you increased
noise immunity, while maintaining signal integrity over
extended distances.
The SCSI Differential Converter contains an internal active
bus terminator which improves cable-matching characteristics.
Remove it for added flexibility.
Extend the working distance of high-speed host-to-host
computers, get remote high-resolution graphics, and store
data. The SCSI Differential Converter provides ideal solutions
for high-speed remote data communications.
Installation is easy. It’s completely transparent to all SCSI-1,
SCSI-2, and SCSI-3 commands and doesn’t require a SCSI
device address. And it can be installed anywhere on the bus
to provide the bus conversion you need.
TYPICAL APPLICATIONS
Translates single-ended SCSI bus signals into differential
bus signals or vice versa, or use two units as a single-ended
to single-ended bus extender.

Interconnect two converters and use them as a single-ended to single-ended bus extender.
Or use one to translate
single-ended SCSI bus signals
into differential signals
or vice versa.
The SCSI Differential Converter interfaces directly with
SCSI interface adapters used in PCs, VME, DEC™, Sun®, EISA,
and Macintosh®host computers. It also extends the working
distance to disk drives, CD-ROM memory systems, and tape
backup peripherals.
Single-ended and differential device termination meets
ANSI X3.131 and Z3T9.2 specifications. And proprietary
switching logic enables the SCSI Differential Converter to
maintain complete SCSI command functionality.

Recognize any of these situations?
• You wait more than 30 minutes to get through
to a vendor’s tech support.
• The so-called “tech” can’t help you or gives you
the wrong answer.
• You don’t have a purchase order number and the
tech refuses to help you.
• It’s 9 p. m. and you need help, but your vendor’s
tech support line is closed.
According to a survey by Data Communications
magazine, 90% of network managers surveyed say
that getting the technical support they need is extremely
important when choosing a vendor. But even though
network managers pay anywhere from 10 to 20% of their
overall purchase price for a basic service and support
contract, the technical support and service they receive falls
far short of their expectations—and certainly isn’t worth
what they paid.
At Black Box, we guarantee the best value and the
best support. You can even consult our Technical Support
Experts before you buy if you need help selecting just
the right component for your application.
Don’t waste time and money—call Black Box today.
