Abstract
A method and apparatus for detecting an improper connection of one or more cables to signal a cable misconnection error. On a board at one end of the cable there is provided a transmit circuit unique to one of the pins or sockets of the connector and at the other end of the cable at an opposite board there is provided a receive circuit that, when the cable is properly connected, receives the signal from the transmit circuit. A misconnection of the cable eliminates the signal from the transmit circuit thus signaling an error at the receive circuit. In addition, semi-dedicated connector positions are also employed so as to assure a detection of a number of different misconnections of the cable, particularly in a multi-cable system.
