When the sensor is
powered up it does not
send any data, that is,
no data is coming to the
PC.
By default, the sensor is set to a
command-response mode (polling
mode). This means that the sensor is
waiting for a data request command
from the data logger.
To change the sensor settings, you
need to open a maintenance
connection to your WS425 sensor
and configure parameter number 5,
Output Interval, to have a non-zero
value and the sensor will
automatically send data through the
serial line.
