Set Output Format
Use the serial line command FORM to change the measurement message
sent by the transmitter on the service port. You can freely define the
output message to include the desired parameters, formatting options,
text strings, and additional fields.
FORM [modifier string]<cr>
where
modifier string = String of parameters and modifiers that defines the
output format, length 1 ... 150 characters.
Maximum length may be shorter when text strings
are used. See Table 9 and Table 10 on page 51,
and examples below.
Command to set default format:
>form /
Example of default output (default depends on transmitter model):
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
...
Command to set output format as CO
2
and T with Modulus-256
checksum:
>form "CO2 =" U4 4.0 CO2 " T =" U3 3.2 t CS2 \r \n
Output example:
CO2 = 479 ppm T = 24.26 'C E9
CO2 = 477 ppm T = 24.27 'C E8
CO2 = 475 ppm T = 24.27 'C E6
CO2 = 475 ppm T = 24.27 'C E6
...
Command to set output format as CO
2
and T, with start of text (ASCII
character 002) and end of text (003) ASCII codes, and without line feed
and carriage return at the end:
>form #002 "CO2 =" U4 4.0 CO2 " T =" U3 3.2 t #003
Output example (ASCII codes not visible here):
CO2 = 817 ppm T = 24.26 'CCO2 = 806 ppm T = 24.27 'CCO2 =
800 ppm T = 24.27 'CCO2 = 788 ppm T = 24.27 'CO2 = 781
ppm T = 24.27 'CCO2 = 768 ppm T = 24.27 'C...
