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 impendence of the first input contact input to a second impedance level when the voltage signal is validated. An input contact circuit is also disclosed.
Une méthode permettant la reconnaissance d'un changement d'état valide dans un signal de communication comprenant des signaux couplés de manière capacitive reçus par un contact d'entrée comprend le maintien du contact d'entrée dans un premier état et une impédance de la première entrée de contact dans un premier niveau d'impédance, validant que le signal de communication envoyé du contact d'entrée est un changement d'état valide, et que le changement du contact d'entrée à un deuxième état et de l'impédance de la première entrée de contact à un deuxième niveau d'impédance si le signal de tension est validé. L'invention porte aussi sur un circuit de contact d'entrée.
