Abstract

A system includes a first electrical connector and a first multiplexer. The first electrical connector has multiple electrical contacts including at least a first data contact, a second data contact, a first power contact and a second power contact. The first multiplexer has a first data input, a second data input and a selector. The first data input is coupled to the first data contact. The second data input is coupled to the second data contact. The selector is coupled to the first power contact or the second power contact. The first multiplexer is configured to; direct the first data input to a first bus and direct the second data input to a second bus, or direct the first data input to the second bus and direct the second data input to the first bus, depending whether a voltage is present at the selector.
