NOTE: Data from the SDI-12 sensors is collected at predefined times, (eg. Every 1 min, 5 mins, 15 mins, ….) and stored in the receiver. The receiver displays the most recent SDI-12 data.

***The receiver will respond to an SDI-12 Logger and appear like multiple SDI-12 sensors !!!

Example: To collect any data from Transmitter #7, issue the 7M! command – and the 4-20mA + SDI-12 + battery measurements are mapped as SDI-12 data.

Each Transmitter can monitor up to 9x SDI-12 variables

(in 1 sensor or several sensors)::
