Abstract

This invention is a signal reading method based on DMX512 Protocol which is executed in a DMX512 non-polarized connected lighting system and uses a microcontroller to read an input signal input in a non-polarized manner, comprising the following steps: firstly, detecting the potential change of an input signal; secondly, determining if the polarity of the input signal is a positive phase or a negative phase according to potential change; if a positive phase is detected in the input signal, then a positive phase receiving procedure is used to interpret the input signal; if a negative phase is detected in the input signal, then a negative phase receiving procedure is used to interpret the input signal; and finally, reading the data carried by the input signal according to the DMX512 Protocol.
