== Introduction ==
Here we provide This is a temporary user manual for SpUpNIC (Spectrograph Upgrade - Newly Improved Cassegrain), the recently upgraded spectrograph at the 1.9-m telescope's Cassegrain focus. We plan to produce instructive instructional video clips and a more comprehensively illustrated wiki in future, but for now this should suffice!once the software has stopped evolving and the remaining modifications have been made to the system.
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 everything that movemoves) 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 may be accessed using the command line interfaces.
We hope that you'll enjoy using SpUpNIC and that you'll be willing to provide the instrument team with feedback and suggestions by emailing lisa(at)saao.ac.za.
