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.
