Abstract

Protocolo de comunicaciones asíncronas para llaves electrónicas de cerraduras y sistemas de seguridad, caracterizado por la utilización de un mismo y único canal para transmitir el reloj y los datos (bits), ese único canal posee dos estados: uno normal de reposo y otro activo cuando existe comunicación y por la utilización de un pulso activo para indicar el comienzo de un bit; utilizándose un pulso activo para indicar la transmisión de un bit 1 y la utilización de un estado de reposo para la transmisión de un bit O; el pulso activo consiste en el mantenimiento del canal de comunicaciones en estado activo durante un breve espacio de tiempo y la utilización de un estado de reposo que permite extraer energía desde el canal de comunicaciones y un estado activo que no impida el mantenimiento de un cierto nivel de energía suficiente para el buen funcionamiento de los equipos conectados al canal de comunicaciones.
