VLD EPICS development¶

Run the IOC¶

• log into hccoda@nps-vme4 from a terminal
  

  ssh hccoda@nps-vme4
  

• execute startup script (located in $HOME/bin)
  

  startIOC
  

Calibration test script¶

• log into hccoda@cdaql3 from a terminal
  

  ssh hccoda@cdaql3
  

• execute calibration test script
  

  cd $HOME/scripts/VLD
  ./vld_calibration_test [0,1]
  

• Usage

  vld_calibration_test.sh [0,1]
