Serial data transmission method and system

摘要

A serial data transmission system practical for use in a high noise environment, for example, in a car to facilitate accurate transmission of serial data between two electronic apparatus and to improve the signal-to-noise ratio and to save system resources at the receiving connector is disclosed to have an additional control line set between the transmitting connector and the receiving connector for transmitting a control signal from the transmitting connector to the receiving connector during transmission of a serial data such that the receiving connector controls the time to receive data and the time to end the receiving action accurately by means of comparing the control signal to a predefined condition, preventing receiving of noises.
