Connecting SDI-12 Instruments
SDI-12 instruments should be connected as shown in the diagram below. See Section
on using the SDI-12 terminal mode to access SDI-12 instruments directly. Also, refer to Appendix E – SDI-12
for detail on the SDI-12 specification.
Each SDI-12 instrument needs to be configured as a separate SDI-12 device in the iRIS (see section 6.3.5). This
allows the user to configure the instrument poll regime separate to the logging.
Next the sensor configuration needs to be linked to the SDI12 device. This is achieved by selecting SDI-12 as
a source type and then the SD-12Device. In the example below the SDI-12 device has been configured on
address zero, polling every 15 minutes at 14, 29, 44 and 59 minute of each hour. Note the log rate of the
sensor configuration matches the measurement interval of the sensor.
