Usually, users will connect to the graphical user interface, but certain diagnostic functions can only be accesses using the command line interfaces. These are all described below.
==The SpUpNIC InterfaceUser Interfaces==
SpUpNIC's control displays are labelled "Monitor 1" and "Monitor 2", and are located to the right of the TCS monitor in the warm room. To launch the SpUpNIC Control GUI, click on the rainbow icon in the menu bar on the left-hand-side of Monitor 1. All of the spectrograph subsystems (e.g. grating angle, slit width, arcs, exposures, guide mirror) are controlled from this GUI.
