Computer Hardware Terms, Glossary and Dictionary
Pinout is a diagram or table used in electronics to describe how a connector is wired. Each pin of the connector has a purpose which is briefly described in the pinout. The pinout can be shown as a simple table or may include a diagram. It is important to make it clear how to view the diagram, saying if it shows you the backside of the connector (where you attach wires to it) or the "mating face" of the connector. Published pinouts are particularly important when different manufacturers want to interconnect their products using open standards.
