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.
