Transparent mode is entered while the computer is communicating with the data logger through
a terminal emulator program such as through Device Configuration Utility or other data logger
support software. Keyboard displays cannot be used. For how-to instructions for communicating
directly with an SDI-12 sensor using a terminal emulator, watch this video.
To enter the SDI-12 transparent mode, enter the data logger support software terminal emulator:
1. Press Enter until the data logger responds with the prompt CR6>.
2. Type SDI12 at the prompt and press Enter.
3. In response, the query Select SDI12 Port is presented with a list of available ports.
Enter the port number assigned to the terminal to which the SDI-12 sensor is connected,
and press Enter. For example, 1 is entered for terminal C1.
4. An Entering SDI12 Terminal response indicates that SDI-12 transparent mode is
