18.6.5  Additional Measurement Commands 

With the additional measurement commands 
aM1! … aM6! 
aMC1! … aMC6! 

(M-Command, data transmission with CRC) 

aC1! … aC6! 
aCC1! … aCC6! 

(C- Command, data transmission with CRC) 

the complete data set of the compact weather station, as defined for the UMB protocol are 
available in a SDI-12 environment as well. 

The measurement values are ordered according to sensor types. 

Equally to the base data sets max. 9 values can be requested with an additional M 
command, while an additional C request allows for up to 20 values. 

The buffer assignment as documented in the following paragraphs has consequently been 
structured in a way that with each M command the buffers D0 and D1 are used. If the 
respective sensor type has more values available the buffers D2 up to D4 will be occupied if 
required. 

 

M1 / C1  

Temperature 

 

M: 8 Values 

 

C: 8 Values 

M2 / C2  

Humidity 

 

M: 8 Values 

 

C: 12 Values 

M3 / C3

M: 4 Values 

 

C: 4 Values 

M7 / C7

M: 4 Values 

 

C: 4 Values 

 

If the sensor type requested with the measurement command is not available with the actual 
variant of the compact weather station (WS200 ... WS600) the station will respond with  

a0000<CR><LF>
