The spectrograph's collimator and camera optics have been replaced, the instrument has a new detector, all of the mechanisms are now under PLC control and the software (both for instrument control + quick-look data reduction) has been completely re-written.
The instrument has two sub-systems, the PLC sub-system (controlling all the things that move) and the detector sub-system (controlling the data acquisition process). The drivers for these sub-systems run as stand-alone processes, and the user interface runs as a separate process on top of these. Typically, users will connect to the graphical user interface(GUI), although certain diagnostic functions can only be accessed using the command line interfaces.
We hope that you will 'll enjoy using SpUpNIC and that you will 'll be willing to provide the instrument team with feedback based on your experience and suggestions by emailing lisa(at)saao.ac.za.
