RCEData pathIssue
Dpm[6] 0Feb3 (L2-3b) connected. Observed timeout waiting for data. Observed TriggersOut lagging wrt TriggerIn during local data taking (96 vs 891 expected). Doesn't lose sync.
Dpm[6]1Feb3 (L2-33b) connected. SampleExtractor shows triggers out lagging wrt Trigger In. Doesn't lose sync.

  • Swap fiber H with F (changes channels in the RTM). 
  • Reset COBs to change DaqMap. Now Feb3 is on dpm13 and dpm14. Observed timeout waiting for data.
  • We moved the hybrids to top FEBs. (L01-t and L23-t). We observed the same issue on L23-t => possibly related to the hybrids?
