EnviroSMART & EasyAG SDI-12 Probe Manual

Note: Refer to notes on Start Measurement (aM! or aMn!) command above.

Soil Moisture Configuration Values (aC4!, aC5! and aC6!)

The Start Concurrent Measurement commands (aC! or aCn!) “aC4!”, “aC5!” and “aC6!” allow all soil

moisture A, B and C constants to be sampled with a single command. Values are gathered in the same

way as for the Start Measurement command (aM! or aMn!), but the Send Data command (aDn!) may

return up to eight(8) values.

A Constants are retrieved with the Start Concurrent Measurement command (aC! or aCn!) “aC6!”

Command Response

aC6! A00016<CR><LF>

The response indicates that 16 A constant values will be available immediately. The controlling device

will then issue Send Data commands (aDn!) to read the values.

Command Response

B Constants are retrieved with the Start Concurrent Measurement command (aC! or aCn!) “aC5!”

Command Response

aC5! A00016<CR><LF>

The response indicates that 16 B constant values will be available immediately. The controlling device

will then issue Send Data commands (aDn!) to read the values.
