Normal operations are performed in the ''Main View'' tab of the SpUpNIC Control interface. [[File:Control_Arc.png|thumbnail]] [[File:Control_Science.png|thumbnail]] On the right-hand-side is a graphical representation of the instrument, which shows the light path through the various components controlled by the GUI. You can click on the guide mirror, arc mirror, rear-of-slit mirror and Hartmann shutters to move them in and out of the beam, and on the arc lamps and slit illumination to switch them on and off. '''Note that since the installation of the instrument selector in February 2024, we no longer move the guide mirror - this has been replaced by the insertion of a fold mirror from the TCS.''' A blue border surrounding the graphic indicates that the spectrograph is configured for acquisition or calibration, i.e. some component is in the beam that would obstruct its path to the science detector. If the system is correctly set up for a science exposure, there will be no coloured frame and the red light-path will reach the detector.
