Abstract

Dispositivo para leer y escribir en diferentes protocolos de transferencia de datos asignados de diferentes tipos de transpondedores. El dispositivo tiene una memoria de transmisión (14) que guarda una secuencia de datos de interrogación del protocolo de transferencia de datos para cada tipo de transpondedor, para iniciar la comunicación. Una memoria de recepción guarda las secuencias de datos de respuesta para cada tipo de transpondedor. Una unidad de envío transmite la secuencia de datos de interrogación asignada por el protocolo a un tipo de transpondedor y a continuación para un tipo difernete de transpondedor. Una unidad de envío (20) envía una secuencia de datos de interrogación para un tipo de transpondedor para determinar si este tipo de transpondedor está cerca del dispositivo (10). si el tipo de transpondedor está presente, el transpondedor envía la secuencia de datos de respuesta a evaluar por la electrónica de evaluación (12) como secuencia recibida de datos de contestados. Si el transpondedor contesta cual no está que no es el tipo dirigido, entonces la secuencia recibida de datos de respuesta se compara con la secuencia esperada de datos contestados para determinar si la secuencia de datos de respuesta es válida. Si no hay transpondedor de primer tipo, el remitente (14) transmite la secuencia de datos de interrogación a un segundo tipo de transpondedor. Ambos transpondedores tienen una frecuencia portadora común de 13.56 MHz. La invención se refiere también al procedimiento de lectura y escritura para los transpondedores.
