Programmable signal transmission method

The invention discloses a programmable signal transmission method, which is suitable for multiple circuit boards and multiple transmission lines. The programmable signal transmission method comprisesthe steps that a circuit board selects one of multiple output signals according to a first conversion signal; a circuit board outputs the selected output signal to the transmission line electrically connected with a pin from one of pins according to a configuration signal; a transmission line transmits the output signal to each circuit board electrically connected to the transmission line; each circuit board selectively receives or ignores the output signal on the transmission line from one of the pins according to the configuration signal; and the circuit board selecting to receive the outputsignal sets a transmission channel of the output signal according to a second conversion signal. 种可程序化信号传输方法，适用于多个电路板及多个传输线。可程序化信号传输方法包括个电路板依据第转换信号选择多个输出信号其中之。个电路板依据配置信号，自其中个接脚输出已选择的输出信号至接脚电性连接的传输线。个传输线传输输出信号至电性连接于传输线的每个电路板。每
