Drive Interface Connectors

Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one
connector matches a tab or a filled-in hole on the other connector. Keyed connectors ensure that the pin-
1 wire in the cable goes to the pin-1 end of the connector. The pin-1 end of a connector on a board or a
card is usually indicated by a silk-screened "1" printed directly on the board or card.
