Campbell Scientific WINDSONIC 2-D Sonic Wind Sensors - Manual (Page 24)

WindSonic Two-Dimensional Sonic Anemometer
The WindSonic4 returns three data points; the datalogger
program must allocate three consecutive input locations
(Edlog datalogger) or a variable array with three elements
(CRBasic dataloggers). CAUTION
When the datalogger issues the aRo! command, the WindSonic immediately
begins transmitting the most current wind measurements to the datalogger.
After receiving the aRo! command, it takes the WindSonic approximately 190
milliseconds ±10 milliseconds to transmit the data. If the aDo! command is
used, it will take slightly longer to retrieve the data because of the additional
handshaking required with the aDo! command. For all practical purposes, a
datalogger can measure up to 4 WindSonic4s at 1 Hz.
TABLE 7-9 lists the datalogger OS version and revision that supports the SDI-
12 aRo! command. The most current datalogger operating systems are
available at the Campbell Scientific website in the Support|Downloads section.
