    keyword=Controlled access activity - DAQ changes

    Brad, Alex and I took controlled access to make following changes to the DAQ.

    1. Added 1881M ADC module in ROC8, slot 9 for the BigBite gas Cerenkov.
    The gate is programmed to be on the front. 

    2. Moved all the Cerenkov ADC signals from ROC5 792 ADC to the new fastbus ADC. Database db_DBB.dat has been updated with new info.

    3. Re-timing circuit on the BigBite has been changed to make a coincidence of T2 and L1A instead of T1 and L1A. The time difference between T1 and T6 was about 4ns. So T0's for the wire chamber have to be re-calibrated to take this into account.
