SDI-12 Configuration for a Hydrolab Sonde
B.1 SDI-12 Configuration
Once the sonde is connected to one of the COM ports in the PC, go
to START MENU>ALL PROGRAMS>HYDRAS3 LT in the PC. This
will start the Hydras3 LT software as shown in
Figure 43 .
Upon starting, the HYDRAS3 LT software scans the available COM
ports in the PC. If a sonde is detected, this information will be
displayed in the Connected Sondes tab of the HYDRAS3 LT
window.
If your sonde is not listed in the Connected Sondes tab, check the
connection to the power supply and the connection to the COM
port.
Make sure the connected sonde is highlighted in the Connected
Sondes window, and click the Operate Sonde button (
Figure 43 ). A
popup configuration window will appear ( Figure 44 ).
