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?
