Example (ASCII and NMEA 0183, device address 0):
Disabling the heating and error messaging:
0SU,S=N,H=N<cr><lf>
0SU,S=N,H=N<cr><lf>
Example (SDI-12, device address 0):
Changing the update interval to 10 seconds:
0XSU,I=10!0<cr><lf>
In SDI-12 mode a separate enquiry (0XSU!) must be given to check the
data content.
Composite Data Message
The parameters to be included in the composite data message aR0 can
be defined in the parameter selection fields of each parameter (aWU,R,
aTU,R, aRU,R, and aSU,R). See parameter tables of each sensor in the
previous sections. See the following examples.
Example (ASCII and NMEA 0183, device address 0):
How 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>
NOTE When changing the bits 9-16 of the parameter selection of any sensor,
the command can be shortened by replacing the bits 1-8 with a single
'&' character, see the examples.
