» 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.
FEATURES
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 operational 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

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 supports all Bi-Tronics Level 1 compatible hardware
and is backward-compatible with Level 2 hardware.
