Serial Line Output Commands
Start Measurement Output
Use the R command to start the continuous outputting of measurement
values as an ASCII text string to the serial line. The format of the
measurement message is set with the FORM command.
R
Example (measurement message in default format):
>r
RH = 26.44 %RH T = 24.27 'C CO2 = 449 ppm
RH = 26.45 %RH T = 24.27 'C CO2 = 449 ppm
RH = 26.43 %RH T = 24.27 'C CO2 = 449 ppm
RH = 26.43 %RH T = 24.27 'C CO2 = 449 ppm
...
Outputting the results continues in intervals issued with the command
INTV. You can stop the output with the S command. Since the interface
is half-duplex, you must enter the commands when the transmitter is not
outputting.
