start server on VME PC:

• got to VME-PC $ ssh 192. 168.10.11
• $ cd ~/GEM_Proto/HV/WebHV/
• $ ./SYMBhv -c HVconfig_CFD.conf

start GUI on hadanapc5:

• $ cd ~/VME/HV_CAEN/build-HVgui
• $ ./HVgui

Now the GUI window opens. Channel 2 is used for the scintillator. Set the trip current to 30 muA and set the max Voltage to 1500 V. Turn up the voltage to 1300 V, now you should be able to see signals.
