EE CAEN HV supply /HV distribution crate setup
====================================

- Connect "Gen" on CAEN to the "Trip" and "Reset" inputs on HV distribution crate

- Connect "Interlock" on CAEN to "HVon" on HV distribution crate

- Set CAEN switches as follows:    
                                                  NIM/TTL -> TTL
                                                  Enable -> Loc Enable
                                                  Interlock -> closed

- Insert 50 ohm terminator in "HVEN" on back of HV card in CAEN

- HV distribution crate clamps when "Gen" is off
  Turning "Gen" on resets the HV distribution crate (ie clears all error indications)

- To change "Gen" from CAEN front panel: - select "utility->status" from Menu
                                                              - toggle "Always" as needed
                                                              - select "OK"
  You need to login with admin status to do this

-  Changing channel settings: - "Main -> Channels" creates list of channels
                                           - "Tab" key moves between menu bar and channel list
                                           - Cursor keys move around display
                                           - to change alphanumeric item, type in new value then 'enter'
                                           - to change toggle value, press space

-  On prototype HV distribution crate:  - Lemo on wire at front panel of control card provides fixed 5V output,
                                                         plug into "trip" input to run HV distribution crate without CAEN control connections
                                                       - Switch, on wires (inside crate to left of input card), is to simulate interlocks on front
                                                         and rear panels. (No interlock switches are installed)

- Note that current monitor outputs on HV distribution crate have an offset which is significant if trying to measure very small currents
  (~2mV = 200nA). However nA currents can be measured if this is taken into account.
