SonTek/YSI
To set SDI-12 SIDEKICK format use (you may also use SONTEK in firmware v7.9 or later):
>sdi12format SIDEKICK
If you need the data to be stored on the Argonaut’s internal recorder (in addition to being logged
onto an SDI-12 data-logger), turn the recorder ON using:
>recorder on
After setup is complete, save your settings using:
>savesetup
To put the Argonaut into SDI-12 data collection mode use:
>SDI12 ON
The Argonaut sends this reply to indicate it is now in SDI-12 mode (see Important Notes #1):
OK
Checking Setup Parameters...
917504 free bytes left in recorder.
Free space is sufficient for 2.31 days of operation.
Recorder mode is NORMAL.
Switching to SDI-12 mode
SDI-12 address is: 1
You should verify that the Argonaut can now accept SDI-12 commands by sending the following
SDI-12 “Send Identification” command and receiving the appropriate response (§A2.5.7).
?I! (You may be required to enter a also; see Important Notes #2 first.)

You can now enter additional SDI-12 commands. When done, make sure you disconnect the RS-
SDI switching plug (Figure A2.6) to complete the process of placing Argonaut in SDI-12 mode.
Important Notes:
1. If the recorder is enabled and already full, the Argonaut responds with an error message and
will not enter SDI-12 mode. To proceed, the recorder has to be either disabled or formatted.
2. Depending on the terminal emulator you are using (SonTerm [for DOS] or SonTermW [for
Windows]), you may be required to enter a to complete the command string.
• SonTerm (for DOS) – Do not enter the terminating . The system recognizes the “!”
character as the command terminator. If you inadvertently send a , you can return
the system to a known state by sending a BREAK, or any other valid SDI-12 command not
followed by a .
• SonTermW (for Windows) – You do enter the terminating , assuming you have set
the File|Communications Mode to SDI-12. If this item is set to RS232/422/485, the system
will act the same as SonTerm for DOS (as described above).
3. If a BREAK is issued to an Argonaut that is in SDI-12 mode, the system will not stop its
operation and will send the following message.
100
112 SonTek SL 79 E272
System is in SDI-12 mode. To switch to RS232 type ?EXIT!
4. While in SDI-12 mode, the serial communications do not support full duplex. Therefore, the
characters you enter are not echoed back to the screen.
