== 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. See the [https://topswiki.saao.ac.za/images_topswiki.saao.ac.za/3/3e/SpUpNIC_2016.pdf '''SpUpNIC paper'''] presented at the 2016 SPIE Astronomical Telescopes and Instrumentation conference in Edinburgh for more information about the instrumentand please cite the SpUpNIC refereed science paper published in the SPIE Journal of Astronomical Telescopes, Instruments and Systems.

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. There is also a rear-of-slit camera that makes it easier to acquire targets and focus the telescope properly.
