Channel Value
DI: At low level, the channel value is 0; at high level, the
channel value is 1.
When the * MST071 shift switch is raised (well cover
change), it turns on and outputs the high level.
PI: The channel value is 0.
Note
If the device has only one 4-PIN terminal, it can only
connect with one sensor as default, but if two channels are
required, exterior connection box would be necessary.
2.4.4 RS485 communication interface
RS485 interface corresponds to 7PINS terminal and the definition is
shown in table 2.7.
