Abstract
Various examples are directed to systems and methods comprising receiving a control signal at a control circuit of a surgical device. The control circuit may comprise a first circuit portion coupled to at least one switch operable between an open state and a closed state. The first circuit portion may be configured to communicate with a surgical generator over a conductor pair to receive the control signal and may comprise at least one resistor coupled to the at least one switch. Methods may also comprise determining the state of the at least one switch based on the value of the resistor.
