<p>PROBLEM TO BE SOLVED: To provide a start-stop synchronization data transmitting method capable of realizing a stable start-stop synchronization communication even with a clock outputted from an oscillator whose oscillation frequency accuracy is low. SOLUTION: In this start-stop synchronization data transmitting method, a master station is provided with a crystal oscillation circuit corresponding to a baud rate fitting transmission channel characteristics, a slave station is provided with a CR oscillation circuit, the master station transmits a preliminarily defined dummy message in a fixed cycle, and each slave station counts a specific edge time interval of the first bit frame of the dummy message with an output clock from the CR oscillation circuit 109, and generates a baud rate clock calculated from the count value to perform start-stop synchronization communication.</p> |
