Abstract (en)
A signal reading method based on a DMX512 protocol is executed in a DMX512 non-polarized connection lighting system, and is capable of non-polarizedly reading an input signal through a micro-controller. Firstly, it is detected that a potential change occurs to an input signal. Then, according to the potential change, it is determined whether a polarity of the input signal is positive or negative. If the polarity of the input signal is positive, the input signal is decoded by using a positive-phase receiving procedure. If the polarity of the input signal is negative, the input signal is decoded by using a negative-phase receiving procedure. Finally, data carried in the input signal is read according to the DMX512 protocol.
