Abstract:
1. A first circuit board connectable to a second circuit board, the first circuit board comprising: at least one set of contacts, each set configured to receive an electrically conductive keypin for bridging a set of the contacts; a detection circuit in signal communication with the at least one set of contacts, the detection circuit productive of a logic signal in response to a set of the contacts being bridged; and a voltage generator responsive to the logic signal and productive of a voltage signal at a connector connectable to the second circuit board; wherein the voltage signal at the connector has a first voltage value in response to the keypin being disposed at a first pin location, and a second different voltage value in response to the keypin being disposed at a second pin location, wherein at least one of the pin locations results in a set of the contacts being bridged; wherein the voltage signal has the first voltage value in response to one keypin being disposed at the first pin location, and does not have the first voltage value in response to the one keypin being disposed at the first pin location and another keypin being disposed at the second pin location; and wherein the voltage signal has the second voltage value in response to one keypin being disposed at the second pin location, and does not have the second voltage value in response to the one keypin being disposed at the second pin location and another keypin being disposed at the first pin location.
