• connection profiles on ctalab computer (odo)
  • Ethernet for internet (eno1) should be connected with "Profile 1" profile
  • Ethernet for media converter (enp3s0) should be connected with " TargetC " profile
• Hooking everything up to power now
  • Found that the 0.5 A level we set was current limiting, specifically to a spike in current at the start
  • We have raised the current limit to 1.0 A and now it seems to be working
  • With 12 V applied through adapter board to FEE (prior to connection), current holds steady at 0.64 A
• Our module is module 3
• Trying to take a pedestal run
  • 12 V bias only for adapter board (module), no HV
  • /working in software base: ~/software/CTA/svn/CCC/TargetIO/trunk/script/SCT_TM/INFN_test_system
    • ./INFN_FEE_QC.py -p -npg -cfg defaults.yaml 3
      • (npg = no function generator)
  • We found that we had to bump up the current limit to 1.2 A
  • Pre-connection:
    • Current goes to 0.65 A and holds steady
  • Connection and during pedestal run:
    • Current goes to 1.09 A and holds steady
      • Is this current level expected?
