You can define the parameters to be included in the composite data message aR0 in the parameter selection fields of each parameter (aWU,R, aTU,R, aRU,R, and aSU,R).
| When changing the bits 9-16 of the parameter selection of any sensor, you can shorten the command by replacing the bits 1-8 with a single '&' character, see the examples. |
Example (ASCII and NMEA 0183, device address 0):
To format a composite data message with average wind direction, average wind speed, temperature, humidity and pressure data when the original composite data message contains following data: maximum wind direction, maximum wind speed, temperature, humidity, pressure, accumulated rainfall, supply voltage and heating voltage:
0R0<cr><lf>
0R0,Dx=009D,Sx=0.2M,Ta=23.3C,Ua=37.5P,Pa=996.8H,Rc=0.000I,Vs=12.0V,Vh=0.0N<cr><lf>Replace the maximum wind direction (Dx) and speed (Sx) with average wind direction (Dm) and average wind speed (Sm):
0WU,R=&01001000<cr><lf>
0WU,R=11110000&01001000<cr><lf>Remove the heating voltage (Vh) and temperature (Th) data from the composite data message, and include the information field (Id):
0SU,R=&00001000<cr><lf>
0SU,R=11110000&00001000<cr><lf>Remove the accumulated rainfall (Rc) from the composite data message:
0RU,R=&00000000<cr><lf>
0RU,R=11111100&00000000<cr><lf>The final composite data message query and response in ASCII:
0R0<cr><lf>
0R0,Dm=009D,Sm=0.2M,Ta=23.3C,Ua=37.5P,Pa=996.8H,Id=HEL___<cr><lf>
