Changing the Settings
You can change the following settings:
- parameters included in the wind data message,
- update interval,
- averaging time,
- speed unit,
- direction correction, and
- NMEA wind formatter.
Make the desired setting with the following command. Select the
correct value/letter for the setting fields, see
Setting Fields on page 95 .
See the examples.
[N] = NMEA wind formatter: T = XDR (Transducer
syntax), W = MWV (Wind speed and angle)
Determines whether the wind message in NMEA
0183 (automatic) is sent in XDR or MWV format.
[F] = Sampling rate: 1, 2, or 4 Hz
Defines how often the wind measurement is
performed. By selecting lower sampling rate the
power consumption of the device diminishes (the
representativeness of the measurement decreases as
well if short averaging time is used with low
sampling rate).
<cr><lf> = Response terminator
NOTE When using MWV wind messages in NMEA 0183, one of the [R]
field's bits 1-6 must be 1.
NOTE If you want representing values for wind speed and direction min and
max values, use long enough averaging time in relation to sampling
rate (at least four samples during the averaging time).
