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>
