Campbell Scientific RTDAQ Software - Manual (Page 253)

Section 8. Real-Time Monitoring and Control Software
When the run-time display screen is started, the display components will have
a red exclamation point in the upper right corner until data is received from
RTDAQ. If data is not displayed, check to see that you are connected to the
proper datalogger.
Once a project file has been created and saved, the display screen can be run
without starting the RTMC Development application. You may switch to the
display of a different project by choosing File | Open and selecting another
RTMC project file. In Run-time mode, you can print an image of the RTMC
display screen by selecting File | Print Screens.
