FEATURES
• 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.
Use your speedy IEEE 1284 laser printer with your async RS-232 hardware!
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
®
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

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.
