A D-Sub connector is a D-shaped connector containing two or more rows of parallel pins
D-Sub connectors are used in computer systems to interconnect parallel and serial buses. The shape acts as a sort of keying as the connector may only be mated in a single orientation. DB-9 connectors are typically used with the RS-232 or RS-485 physical layer recommended standards.
