FE ATUR ES

» Converts serial to IEEE 1284 parallel.
» Runs at speeds up to 115.2 kbps.
» Supports two IEEE 1284 Bi-Tronics modes:

Compatible and Nibble (switchable).
» Super compact, pocket size.
» LEDs provide at-a-glance monitoring.
» Power choices: from both interfaces

or from an external power supply.
» Features 10-kV ESD (electrostatic discharge)

protection on the serial interface.

OVERVIEW

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

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.

Nibble operations into standard HP
sequences. This enables operation with standard printer drivers.
