String
The incoming data string, check this against the chosen

data indicator is red.
The
Output COM Port
section allows the user to export data from the Gemini software to
third party applications. Changing the
Encode
option will alter the output. For more details on
the data formats for each string, please refer to Appendix F,
Gemini Software String Encode

The data age status indicator will show the status of each port. A grey indicator
means no data is present, red is for an incorrect data string, yellow indicates an
incomplete data string and green is for normal operation.

option will hide the Mode, Sync, Decode, Max, Age, Hz and String
information.

Port 1.
