Note：For LSD102A、LSD131A、LSD151A, this port is NPN output port（open collector），there will be low lever
output when object is detected at the detection area.
For LSD121A, LSD151A, this port is I/O input port, When the input is suspended or connected to low, it
is identified as high level and output as "0" in the communication protocol.
