with pin 3 of the SAA ports

instability.

CURIOSITY NOTE!
The DB- designation for D- Sub connectors is from Cinch Corp’s part numbering system.
The proper Cinch designation for a 15 pin D- Sub connector is a DA- 15p (plug) or DA- 15s
(socket) not DB- 15!
Other Cinch designations for D- Sub connectors are; DE- 9, DB- 25, DC- 37 and DD- 50.
Our thanks going out to Mike Schweizer, for contributing this information.
