WindSonic Two-Dimensional Sonic Anemometer

6.4 Campbell Scientific Factory Default Settings for the

WindSonic1

The default settings for the WindSonic1 were changed in February 2013 to

improve operation in cold temperatures. Sensors with the newer settings have

a white dot next to the connector on the underside of the sensor (see FIGURE

6-1). They also include both a yellow and a white heat shrink label on the

cable; older sensors included two white heat shrink labels.

• Continuous polar wind (M2)

• Wind speed in m s

–1

(U1)

• Field formatted, comma separated values (O1) [changed in February 2013]

• Terminate records with a carriage return and line feed (L1)

• 1 Hz output frequency (P1)

• Baud rate – 9600 baud (B3) [changed in February 2013]

• Power up message (H1) [changed in February 2013]

• Address set to “Q” (NQ)

• Data bits and parity — 8 bits, no parity (F1)

• RS-232 interface (E3)

• Analog output 0 to 5 Vdc (T1) — does not apply

• Analogy range 0 to 30 m s

–1

(S4) — does not apply

• Analog wrap around 0 to 360 degrees (C2) — does not apply

• Minimum direction velocity (K50)

WindSonic1s with the newer default settings will not work with

older programs or Short Cut 3.0 or older. Appendix B provides

information about updating an older program for a WindSonic1

with the newer settings.
