of environments: sync
or async, 2- or 4-wire,
half- or full duplex,
point-to-point or
multipoint.
13 selectable data
rates to choose from
Extremely tolerant to
heat and humidity.
Transmits data up to
12 miles.
Built-in 2000-VAC
transformer isolation
and high-speed surge
protection.
V.52 and V.54 test
modes.
T
hink of your operating
environment as an obstacle
course. There are all sorts of
hurdles to overcome. If you’re not
worrying about spikes, then
there’s always excessive heat.
Or maybe you’re set up for 2 wire
operation and now you need to go
to 4 wire. Or your application calls
for multipoint configuration when
you really need point to point.
This is no time for a wimpy line
driver. You need versatility. You
need equipment that can handle
extreme conditions. You need the
Async/Sync Industrial Line Driver.

KeyFeatures
ASYNC/SYNCINDUSTRIALLINEDRIVER
The Async/Sync Industrial
Line Driver is loaded with features
that not only drive your data, but
also keep it safe from harmful
conditions:
• Built in surge protection
keeps your equipment safe
from spikes.
• Transformer isolation guards
against ground loops.
• Extreme temperatures
ranging from 14 to 158°F
( 10 to +70°C) won’t affect
performance.
And when it comes to being
prepared for all situations, you
can’t beat this kind of flexibility:
• 2 wire (half duplex) or
4 wire (full or half duplex)
operation.
• Point to point or multipoint
configuration in both 2 and
4 wire applications.
• Data is transmitted in async
or sync mode.
• 13 selectable data rates.
• Transmit data up to 12 miles
(19.3 km).
Other features include three
clocking selections (internal,
external, or receive recover),
equalization, and an anti
streaming timer. You also get
comprehensive diagnostics
including a V.52 compliant BERT
pattern generator/detector and
V.54 LAL and RDL tests. Both RDL
and LAL modes can be controlled
by a manual switch or via the
V.24/RS 232 interface.

Specifications
Recogni e 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.
