Abstract
A surgical device control circuit. The control circuit may comprise a first circuit portion comprising at least one first switch. The first circuit portion may communicate with a surgical generator over a conductor pair. The control circuit may also comprise a second circuit portion comprising a data circuit element. The data circuit element may be disposed in an instrument of the surgical device and transmit or receive data. The data circuit element may implement data communications with the surgical generator over at least one conductor of the conductor pair.
