7.4.1 Digital inputs
The inputs are electrically isolated from the operating voltage of the reader and
can be operated independently of the polarity of the input signal� For this purpose,
there is a common pole for the inputs (switching input CMN)�
Depending on the application, the inputs can be operated electrically isolated with
an external voltage or not electrically isolated with the operating voltage of the
reader�
