| abstract |
A plug connector comprises a body 42 and a connector tab 44 extending from the body and configured to be inserted into a corresponding receptacle connector. The tab carries external contacts 106 on a first surface, including first and second data contacts configured to enable communication using a first communication protocol and an ID contact configured to carry information that identifies the communication protocol associated with the first and second data contacts. Circuitry 108a, 108b coupled to the ID contact is configured to participate in a handshaking algorithm that communicates the information that identifies the communication protocol (eg USB, UART) associated with the first and second data contacts over the ID contact. The plug may also have further contacts on a second surface of the tab, configured so that the plug may be used either way up. |
