If the DigiTemp is supplied without a connector, the user is responsible for connecting the sensor to the data
collection platform. A user can attach their own connector, or connect the cable via a terminal strip, or directly
wire it to device electronics.
1.4 Operation
The FTS DigiTemp is an SDI-12 device and is powered by the +12 V DC power supply on the SDI-12 bus.
For details on the SDI commands used by the sensor, see Chapter 2 SDI Commands.
1.5 Configuration
The DigiTemp is shipped with default address 0 (unless shipped as part of an integrated FTS system). The only
configuration available is to change this address if necessary in systems with more than one SDI-12 sensor on
the same bus. Refer to section 2.3.3 Change Address for instructions on setting the sensor’s address.
1.6 Calibration and maintenance
Calibration is never required. Maintenance consists of periodic checking for cable wear.
Please contact FTS technical support (see manual front pages) if the unit ceases to operate properly.
