Old Instruction from Eric Fuchey (PDF)
Instructions from BBCal
GRINCH shares the same mainframe as BBCal (LeCroy and RPi, interfaced through a JAVA GUI). Please follow the instructions HERE
If the HV settings in the EPICS interface are lost (just 0s), follow the instruction to load the settings through the JAVA GUI. The GRINCH settings file are in the GRINCH folder within the hv_set folder. The GRINCH channels are on rpi17, slots S10-S15.
Sometimes, the JAVA GUI doesn't show the HV set values, check if the EPICS GUI load them, you can trust the EPICS GUI
