6.6 Connecting SDI-12 Instruments. (iRIS 320 / iRIS 320V only)

SDI-12 instruments should be connected as shown in the diagram below.

See Section 4.3.3 for information on using the SDI-12 terminal mode to access SDI-12 instruments directly.

Also, refer to Appendix C – SDI-12 (iRIS 320 / 320V only) for detail on the SDI-12 specification.

NOTE: The original (PCB revision 1.1) iRIS 320 / iRIS 320V models supported the connection of SDI-12 instruments via a psuedo SDI-12 interface. See Section 13.3 in Appendix E.
