Setting fields - WXT530

Bits 1-8 determine the parameters in the data message obtained with the following commands:

• ASCII: aR1 and ar1
• NMEA 0183: $--WIQ,XDR*hh
• SDI-12: aM1,aMC1, aC1, and aCC1
• SDI-12 continuous: aR1 and aRC1

Parameter	Description
[I]	Update interval: 1 ... 3600 seconds
[A]	Averaging time: 1 ... 3600 seconds Defines the period over which the wind speed and direction averaging is calculated. Same period is also used for maximum and minimum calculation. See Appendix D Wind Measurement Averaging Method on page 201 for difference in averaging practices when A<I and A>I.
[G]	Wind speed max/min calculation mode: 1 or 3 seconds G =1: Traditional max/min calculation is performed both for speed and direction. G =3: Gust & lull are calculated for wind speed, while direction calculation is as it is with G =1. In the output messages, gust & lull replace the wind speed max/min values (Sx, Sn), respectively.
[U]	Speed unit: M = m/s, K = km/h, S = mph, N = knots
[D]	Direction offset: -180 ... 180°, see Wind Direction Offset on page 51.
[N]	NMEA wind formatter: T = XDR (transducer syntax), W = MWV (wind speed and angle) Defines whether the wind message is sent in XDR or MWV format.
[F]	Sampling rate: 1, 2, or 4 Hz Defines how frequently the wind is measured. Lower sampling rate reduces the power consumption, but it also weakens the measurement representativeness.
