Abstract
A method for recognizing a valid change of state in a communication signal including capacitively coupled signals received by an input contact includes maintaining the input contact in a first state and an impedance of the first contact input in a first impedance level, validating that the communication signal sent from to the input contact is a valid change of state, and changing the input contact to a second state and the impedance of the first input contact input to a second impedance level when the voltage signal is validated. An input contact circuit is also disclosed.
