Abstract

A method to automatically switch the transmission direction continuously with the anti-interference function comprises a main apparatus, a first serial port, a transmitting line, at least a sub-apparatus, and at least a second serial port set on the sub-apparatus, wherein the transmitting line is connected to the first and the second serial ports. At least a sub-signal is delivered when the main apparatus generates a command signal from the first serial port synchronously, the bandwidth of the sub-signal or sub-signal set is equal to that of the command signal and the value of voltage is less than that of the command signal, and it is received by the second serial port of sub-apparatus since the second serial port is preset to recognize the sub-signal. The sub-apparatus receives the command signal and the sub-signal to answer an answering signal to the main apparatus for accomplishing the sub-communication. Since the noise interference results in missing the data packet during the transmission between the main and sub-apparatuses, the phenomenon of sub-apparatus delay due to repetitive transmission can be overcome by the present invention, the smoothness and stability of the data transmission between the main apparatus and the sub-apparatus can be ensured, and each sub-apparatus can further be operated synchronously.
