●Il formato dei dati e la velocità di trasmissione possono essere modificati in relazione a future migliorie.

●Nella trasmissione/ricezione di dati, il PC è il Master (principale) e il Target Set lo Slave (secondario).

●Non si dovrebbe ricevere altro stato che la Set Key Function. (è possibile un certo ritardo dovuto alla velocità di comunicazione).
