Get more out of your equipment with the IEEE 1284 Serial→
Parallel Converter from Black Box. Use your speedy IEEE 1284 laser
printer with your async RS-232/423 hardware. You can use this
converter with all your hardware equipped with an IEEE 1284
Bi-Tronics
®
parallel interface.
This tiny box gives you lots of op erational options because it works
in either Level 1 Compatible or Nibble modes (according to the IEEE
1284 standard). So it supports the high speeds—up to 115.2 kbps—
necessary for graphics-intensive laser-printer applications. Depending
on your equipment, all you have to do is set a switch to change
modes.
Conversion is simple. On the serial side, the converter translates
Nibble operations into standard HP
®
LaserJet® IV serial printer escape
sequences. This enables operation with standard printer drivers.
On the parallel side, the converter translates all commands received
from the PC or other serial devices into Bi-Tronics Nibble operations or
Compatible operations.
The converter support s all Bi-Tronics Level 1 compatible hardware
and is backward-compatible with Level 2 hardware.

Recognize any of these situations?
• Youwaitmorethan30minutestogetthrough
to a vendor’s tech support.
• Theso-called“tech”can’thelpyouorgivesyou
the wrong answer.
• Youdon’thaveapurchaseordernumberandthe
tech refuses to help you.
• It’s9p.m.andyouneedhelp,butyourvendor’s
tech support line is closed.
According to a survey by D ata Communi cations 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.

IEEE 1284.
Introduced in 1994, the IEEE 1284 standard addresses
data-transfer speeds and distance for parallel inter faces.
Standard parallel interfaces support speeds of up to 150 kbps
at distances of up to 6 feet (1.8 m); IEEE 1284 parallel interfaces can send your data over 100 times faster at up to 5
times the distance!
Although the Centronics
®
interface enabled only
unidirec-tional computer-to-peripheral data flow, the
IEEE 1284 interface enables bidirectional flow so peripherals
can send data to the computer.
The IEEE 1284 standard covers five separate parallel
modes, from the original Centronics (with which it’s
compatible) to the high-performance Enhanced Parallel
Port (EPP) mode.
The computer negotiates with the attached device
to deter-mine which mode to use.
