== Introduction ==
This is the current 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 instructional video clips and a more comprehensively illustrated wiki once the software has stopped evolving and the remaining modifications have been made to the system. See the [https://topswiki.saao.ac.za/index.php/File:SpUpNIC_2016.pdf/ SpUpNIC paper] presented at the 2016 SPIE Astronomical Telescopes and Instrumentation conference in Edinburgh for more information.
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.
