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.
5.22.1 WS425 AB NMEA Standard Data Message
The standard variable length, comma-separated, MWV wind message is defined by NMEA
0183 V as follows:
$WIMWV,,,,,*
$WIMWV
Fixed text

Wind angle 0 to 359 degrees

Reference: R = Relative

Wind speed

Wind speed unit:
• K = Kilometers per hour
• M = Meters per second
• N = Knots
Chapter 5 – Operation
143



Status:
• A = Data valid
• V = Invalid data
*
Fixed text

Checksum (bit XOR, excluding $ and *)

Carriage return code, ASCII 0DH

Line feed code, ASCII 0AH
When the NMEA Standard profile is selected, the
autoInt parameter must have anon- zero value since no polling command is defined for this profile.
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 NMEA Extended Profile
(v. When the WS425 AB NMEA Extended profile is selected, you can set WMT700 to send messages based on the configured automatic message interval or poll data using the
$WIP
command.
