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<cr>

Example (measurement message in default format):

>r

RH = 21.71 %RH T = 23.13 'C

RH = 21.72 %RH T = 23.12 'C

RH = 21.77 %RH T = 23.12 'C

RH = 21.77 %RH T = 23.12 'C

...

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.

Stop Measurement Output

You can stop the measurement output with the S command:

S<cr>
