A Ring Imagining Cherenkov Detector (RICH) was built to significantly improve the particle identification in CLAS12 and achieve a separation between pions, kaons and protons in the 3 to 8 GeV/c momentum range. The RICH photo matrix consists of 391 HAMAMATSU multi-anode photomultipliers with 25,024 pixels in total. The RICH data is recorded through front-end electronics specially designed at JLab for this detector. Experimental Physics and Industrial Control System (EPICS) is used for the RICH slow control. The data is displayed on a graphical user interface (GUI). A Scalar GUI has been generated to visualize the detector performance and monitor the data quality.
