The FAULT signal goes false (high) when all the above
conditions are corrected.
The Centronics bidirectional parallel interface is designed to
provide plug-to-plug compatibility with a 36 pin Amphenol
57-40360 (or equivalent) connector that connects to an
Amphenol 57-30360 (or equivalent) connector. The cable
length has been certified at 6 feet, and will be the twisted pair
type 22AWG -15 pairs. Pin assignment and functions for the
Centronics interface are designated in Figure A.3.
