19.8.6 Measurement Commands
Command Examples are shown for unit ID 01
19.8.6.1 Single Measurement XDR format
Command identifier:
P9
Parameter:
none
Command example:
Command: *0100P9<CR><LF>
Response (wind data not activated):
$WIXDR,P,<pressure in bar>,B,0,C,<air temperature °C>,C,0,H,<rel. Humidity
%>,P,0<CR><LF>
Response (wind data activated):
$WIXDR,P,<pressure in bar>,B,0,C,<air temperature °C>,C,0,H,<rel. Humidity
%>,P,0<CR><LF>
$WIMWD,<wind direction °>,T, < wind direction °>,M,<wind speed kts>,N ,< wind speed
m/s>,M<CR><LF>
Serial numbers of pressure and T/H sensor are not available and set to 0.
19.8.6.2 Continuous Measurement XDR format
Command identifier:
PP
Parameter:
none
Command example:
Command *0100PP<CR><LF>
After this command the device will start to transmit the result message as defined in for the
single measurement automatically with the interval defined by the transmission interval
command (see 19.8.7.1) or set by the UMB Config Tool.
The default interval is 60 seconds, minimum allowed interval is 10sec, maximum interval is
43200sec (=12h).
The continuous mode will be stored in the E2PROM of the device, so that after a reset the
device will continue to transmit automatically.
The continuous mode is terminated by a Single Measurement Command (19.8.6.1,
19.8.6.3).
19.8.6.3 Single Measurement 0R0 Format
Command identifier:
PB
Parameter:
none
Command example:
Command *0100PB<CR><LF>
Response:
0R0,Dm=<wind dir.>D,Sm=<wind speed>M,Ta=<air temp.>C,Ua=<rel. humidity>P,Pa=<air
press.>B,Rc=<precip. diff.>M, Pt=<precip. type>N<CR><LF>
