A

re legacy DOS systems still

doing important work for you?
Do they get bogged down printing
page after page of data? Now you
can clear your screen and get
back to work with the Data Buffer
II and the HS (High-Speed) Data
Buffer II.

These buffers streamline
bidirectional communication
between two RS-232 devices
by buffering data, eliminating
bottlenecks between your
computer and your printer, plotter,
or other serial device.

The print buffer that keeps your

legacy system working at full speed.

Key Features

DAT A BUFFER II AND HS DATA BUFFER II

Each buffer’s input and output
port can support different baud
rates. This, together with proper
memory sizing, can completely
eliminate the need for flow control
at the host, providing fast,
efficient, and error-free data flow.

Eight-position DIP switches
enable you to set data rates,
hardware or software flow
control, and parity. Each port can
be configured independently.

The buffers have multiple­copy capabilities, enabling them
to print up to 99 copies of a file. To

cancel a job, a simple press of the
reset button cancels all the data
in the buffer.

The buffers can generate self­test messages from the output
port so you can print out
diagnostics on your printer.

Configure the Data Buffer II
to accept data at speeds ranging
from 300 bps to 19.2 kbps. And
the HS Data Buffer II accepts
data as fast as your PC can send
it at any of 16 selectable data
rates ranging from 4800 bps to

115.2 kbps.

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.
