ABSTRACT:
A method for detecting data outputted from an optical coupler is presented comprising the steps of setting a reference recognizing level by inputting the data in an initial state to an A/D converter; recognizing the level of the data in a noninitial state as high if the level of the data at the non-initial state is greater than the reference recognizing level; recognizing level of the data in the non-initial state as low if the level of the data at the non-initial state is less than the reference recognizing level; and setting the level of the data at the non-initial state to equal the reference recognizing level if the level of the data at the non-initial state is recognized as low.
