SCSI-1, SCSI-2, and
SCSI-3 compatible.

W
ith 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 inter-
connect two of the 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.

KeyFeatures
SCSIDIFFERENTIALCONVERTER
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.
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.

T
he 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.
