3.10. SDI-12 Interface Commands
Starting with firmware version 7.5, the Argonaut-XR and SL offers internal SDI-12 (Serial-
Digital Interface) capabilities that require no external devices or converters. Appendix 2
describes the internal SDI-12 interface support in detail. The Argonaut commands are described
in this section, and the format of the SDI-12 commands is described in Appendix 2.
sdi12 ON
• Places an Argonaut-XR or SL system in the SDI-12 interface mode.
• To exit the SDI-12 interface mode, you must use the ?EXIT! command described below.
sdi12address [d]
• Default parameter: 1
• Parameter range: 0 through 9
• Without parameter: returns either the current SDI-12 interface address (if the SDI-12
interface option is installed), or an error message (if the SDI-12 option is not installed).
• When used with a valid integer parameter, sets the Argonaut’s SDI-12 interface address.
• If more than one sensor is to be connected to the SDI-12 bus, make certain each sensor has
a unique address.
sdi12format [SIDEKICK|SONTEK]
• When given without parameter, returns the current data output format being used.
• When given with a valid parameter, sets the data output format. Appendix 2 describes
these two formats in detail.
?EXIT!
• Executing this command causes the Argonaut to exit the SDI-12 interface mode and return
to the standard Argonaut operating mode.
