• White to Control Port C1/SDI12

• Black, Orange, Clear to G

2. In the LoggerNet Connect screen navigate to the Datalogger menu and

select Terminal Emulator. The “Terminal Emulator” window will open.
In the Select Device menu, located in the lower left-hand side of the
window, select the CR200Series station.

3. Click on the Open Terminal button.

4. Press the <enter> key until the datalogger responds with the “CR2XX>

prompt. At the “CR2XX>” prompt, make sure the All Caps Mode box is
checked and enter the command SDI12 <enter>. The response
“SDI12>” indicates that the sensor is ready to accept SDI-12 commands.

5. To query the sensor for its current SDI-12 address, key in ?! <enter> and

the sensor will respond with its SDI-12 address. If no characters are typed
within 60 seconds, then the mode is exited. In that case, simply enter the
command SDI12 again and press <enter>.
