    keyword=ROC 4 Missing ADC Gate

    Since yesterday during the middle of run 2014, the ADC gate for the module
    in ROC 4, slot 21 has been missing. I noticed that during the replay
    last night that the BPM and raster information was missing. This
    morning I discovered that the event readout for ROC 4 was mostly empty.
    Plus the datascan indicated that it wasn't seeing this ADC.

    I found that their was no input for the cable going to the ADC gate in
    slot 21. I think it might have accidentally gotten unplugged when
    Kalyan and I were looking at the gates for the coincidence yesterday
    evening.

    Starting with run 2049, this problem has been corrected and there is now
    real data coming from ROC 4.
