13.35 Swapped HDMI cables from master MACB to MACB #3 & #7
      for HDMI cables from MACB #7 ports 1 & 2 to MACB modules #8 & #9

      ReSYNC and stsrem wide test failures - see attachments 1-5

15.00 Swap HDMI cable from MACB #2 port 1 to MACB #3 next

      ReSYNC and system wide test fails - see attachments 6-10

      *Conclusion* all of HDMI cables between HDMI cable from nnaida6 and master MACB
      have now been swapped for other HDMI cables between MACB # 7 and MACB # 8, 9, 10
      but we still observe ReSYNC and clock issues 

16.05 CG points out that I have misinterpreted Elog 258 - switch back MAC
      mode settings to the following

      MACB #  1  2  3  4  5  6  7  8  9 10 11      spare 1   spare 2
      Mode    5  2  2  3  3  3  3  3  3  3  3
      Rev B      y  y                              50MHz?    y

      FEE64 power cycle

      ReSYNC and system wide fails - see attachments 11-16


16,50 Re-considering options
      Install MACB #11 (rev B) mode 0
      Will attempt to use 25MHz correlation scaler clock NIM output from master MACB to BRIKEN+RIBFDAQ

      Power cycle FEE64s

      ReSYNC OK
      System wide checks OK but some issues remain - see attachments 17-25

17.10 DAQ starts
      Writing to disk file R115, merge rate 0.9M data items/, TapeServer ~7Mb/s

17.20 Analysis of R115_1 confirms ADC data synchronised - see attachment 26

17.25 MERGE stats look OK - see attachments 27-29

17.35 System wide tests SYNC errors & SYNC pulses OK

17.38 DAQ stalled - manual start of ORNL clover LN2 fill cycle by Nishimura-san
      Most recent file R115_5 last accessed 17.38

      DAQ stop OK

      Disable histogram and data transfer #1 
      DAQ RESET
      DAQ SETUP
      Restart merger and TapeServer
      Enable histogram and data transfer #1 

17.47 DAQ start (R116)

17.58 DAQ stopped again at end of fill cycle.
      1. Disable histogram and data transfer #1
      2. DAQ RESET
      3. DAQ SETUP
      4. Restart merger and TapeServer
      5. Enable histogram and data transfer #1 
      Had to repeat 1-5 multiple times to get all links working with the merger. R117 created during this (empty).

18.08 Run R118 started.

18.45 TD changing things for runs R119-R120.

18.50 Run R121 started.
      First few minutes are pulser run 30-10,000 @ 250Hz on coarse dial.

18.54 Beam ON.
      Continuing R121. Pb shield immediately after final MUSIC detector.

21.35 DAQ continues OK
      Most recent file R121_30

      All system-wide tests OK *but* note nnaida5 now fails clock status test in addition to combinations of
nnaida7/8/15/16

21.45 R121_32 ADC data synchronised

Overnight

Phong Vi completed the pulser walkthrough interrupted earlier this evening.
BNC PB-4 amplitude settings 30,000 - 20,000 @ 10,000 step, 8,000-2,000 @ 2,000 step  
The data is in files R121_62, _63 and _64 (which have been copied to d05 for further analysis).
