(Wind sensor only) Select True north or Magnetic north depending on
the actual alignment of the wind sensor. See also Configuring station settings
(page 79).
Sensor ID
Type the ID of the sensor, when applicable.
In the poll mode, the ID must be defined and must match the ID in the sensor.
Otherwise the poll command that is sent from the display is not correct.
The display uses asterisk (*) as wildcard character. It means that any character is
accepted when receiving sensor ID in the message.
If several sensors are using one communication channel in the autosend mode,
you have to create message IDs for each of them.
If several sensors are using dierent communication interfaces in the autosend
mode, it is a good idea to create the IDs to check the functioning of the
interfaces.
Sensor di to ref. alt. (m)
(Pressure sensor only) The dierence between sensor altitude and reference
altitude. When the sensor is installed below reference altitude, the value is
negative.
