h1. VLD EPICS development 

 h2. Run the IOC 

 * log into hccoda@nps-vme4 from a terminal 
 <pre> 
 ssh hccoda@nps-vme4 
 </pre> 
 * execute startup script (located in $HOME/bin) 
 <pre> 
 startIOC 
 </pre> 

 h2. Calibration test script 

 * log into hccoda@cdaql3 from a terminal 
 <pre> 
 ssh hccoda@cdaql3 
 </pre> 
 * execute calibration test script 
 <pre> 
 cd $HOME/scripts/VLD 
 ./vld_calibration_test [0,1] 
 </pre> 
 > * Usage 
 <pre> 
   vld_calibration_test.sh [0,1]

 <pre> 
  0: always high (should be Periodic trigger), 
  1: random trigger only 
  2: FP_trigger 
 </pre>
