    keyword=Re: ROC 4, Slot 18 (1875 TDC) Missing Gates in Buffered Mode

    I've looked at a few runs taken for the left HRS in buffered mode. The
    events that have a synch problem all are missing gates from the 1875 TDC
    in ROC 4, slot 18. I also checked ROC 3 for these same events and I do not
    see a problem for this ROC. For these events, the first word is
    '0xdc0000ff' in the ROC 4 readout, which if I remember correctly is the
    missing gate flag. The datascan is '00202200' for these events and should
    be '00242200' for normal events.

    As a follow up run 20138 (unbuffered) has not seen any missing synch's in
    the first 53679 events.
