1) NMEA standard defines the usable transmitter IDs. WI means wind sensor and it is typically used when there is no need to
especially identify the sensor. In the display you can use wildcards (**) as the ID. When sensor ID is needed (for example, in
polling) , Vaisala sensors use “P” + 1 character between A and Z.
Example or MWV message
$WIMWV,320,R,15.0,M,A*0B<CR><LF>
Polling MWV message
When you select MWV message and poll mode in the message settings, the display sends a
poll command according to the WMT700 NMEA MWV profile.
$WI<id>Q,MWV*<chk><CR><LF>
Value <ID> is the 2‑character Sensor ID set in the message settings. The first character is P
and the second character is the WMT700 ID (for example, A).
Example of polling command
$WIPAQ,MWV*72

WMT700 data message 24
WMT700 data message 24 reports wind measurement and self-diagnostics data. The
checksum is included in the message. WMT700 calculates the checksum by applying 8‑bit
XOR for all bytes between checksum calculation start point and end point. The result is
printed as a 2‑digit hexadecimal value.
