where
<ref> = Reference:
R = relative
T = true
<spd> = Wind speed
<uni> = Wind speed unit:
K = kilometers per hour
M = meters per second
N = knots
<sta> = Status:
A = data valid
V = invalid data
* = Fixed text
<chk> = Checksum (8-bit XOR, excluding $ and *)
<CR> = Carriage return code, ASCII 0DH
<LF> = Line feed code, ASCII 0AH
NOTE
When the NMEA Standard profile is selected, the autoInt parameter
must have a non-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. WMT700 reports 999 for wind direction and
999.9 for wind speed.
WS425 NMEA Extended Profile (v. 0183)
When the WS425 A/B 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.
Configurable Parameters
Table 15 on page 52 lists the configurable parameters and their allowed
and default values for the WS425 A/B NMEA Extended profile.
