Wind speed

Wind speed unit:
K = Kilometers per hour
M = Meters per second
N = Knots

Checksum (bit XOR, excluding $ and *)

Carriage return code, ASCII 0DH

Line feed code, ASCII 0AH
Missing Readings
If data is missing due to a measurement problem, the NMEA messages show "V" in the status field. Wind speed and wind direction fields are left empty WS425 AB ASCII Profile
In Vaisala WINDCAP Ultrasonic Wind Sensor WS425 User's Guide, this profile was called the Handar mode.
The following table lists the configurable parameters and their allowed and default values for the WS425 AB ASCII Profile.

The parameter has no protocol-specific default value. It is determined separately in the configuration code.
2) Wind speed unit and COM digital communication interface are defined in the order form. Default setting maybe any of the
allowed options, and it can be verified from the unit’s configuration code.
