Automatic Mode
When NMEA 0183 v3.0 automatic protocol is selected, the transmitter
sends data messages at user configurable update intervals. The message
format is the same as in the MWV and XDR data queries. The NMEA
wind formatter parameter in the wind sensor settings determines
whether the wind messages are sent in MWV or XDR format.
You can use ASCII data query commands aR1 , aR2 , aR3 , aR5 , aR ,
aR0 and their CRC-versions ar1 , ar2 , ar3 , ar5 , ar and ar0 also in
NMEA 0183 protocol. The responses to these commands are in
standard NMEA 0183 format.
For information message formatting the messages, refer to Chapter 8
Sensor and Data Message Settings, on page 127 .
Automatic Composite Data
Message (aR0)
When automatic composite data messaging is selected, the transmitter
sends composite data messages at user configurable intervals. The
message structure is the same as with the composite data query
command
aR0 and contains a user configurable set of wind, pressure,
temperature, humidity, precipitation and supervisor data.
Example (the parameters included can be chosen from the full
parameter set of the commands aR1, aR2, aR3 and aR5):
$WIXDR,A,057,D,1,S,0.6,M,1,C,22.6,C,0,H,27.1,P,0,P,1013.6,H,0,V,
0.003,I,0,U,12.0,N,0,U,12.4,V,1*67<cr><lf>
Example (rain and voltage parameters removed):
$WIXDR,A,054,D,1,S,0.4,M,1,C,22.5,C,0,H,26.3,P,0,P,1013.6,H,0*79

For information on selecting the parameter set in the response message,
refer to
Chapter 8 Sensor and Data Message Settings, on page 127 .
Automatic composite data messaging is in concurrent, not alternate
mode to either the polled or automatic modes.
