Abstract

Procedimiento de transmisión de datos entre un equipamiento de referencia y un equipamiento seguidor, tales como una tarjeta de microcircuito y un terminal de lectura/escritura de dicha tarjeta, caracterizado porque comprende las siguientes etapas consistiendo en: (a) agrupar, en un equipamiento emisor, los datos elementales de un mensaje que debe transmitirse en forma de una serie de, por lo menos, un dato elemental constituido de una continuación (12) de señales numéricas elementales (b0, ... b7). (b) transmitir a un equipamiento receptor dicha serie (12) de datos numéricos elementales precediéndola de señales de sincronización (10) que constituyen, con la serie de datos elementales, una trama (8), las características de duración y de posición de las señales numéricas elementales (b0, ... b7) de cada dato elemental y las señales de sincronización (20, 22, 24, 26) son específicas al equipamiento de referencia y conocidas por el equipamiento seguidor.
