I have provided two ways for interfacing with the OtterVIS LGL spectrophotometer:

1. A very simple graphical user interface (linux).
2. A very simple command line interface (linux and macOS).

Look at tcd1304.wordpress.com for more details.

The graphical user interface still lacks many of the features originally intended, but recently Jens-Ulrich Fröhlich has written a Java based GUI which should work on both Windows and Linux. You can find it on his blog Leaves of science.
