keyword=Re: Restored to Previous ADC channels for S2m
I had a problem with getting a signal from channel 0 in the ADC in
Slot 25 of ROC 3. I did switch ribbon cables, but then I wasn't seeing
any signal from this batch of channels. I decided to go back to the
original channels used (48-63). I restored the pedestals in db.L.s2.dat.
During the pass change on Thursday, I can investigate further, but I need
more time to do so.
I decided it was better to use channels that have a signal with a
possibility of shifting pedestals than taking the chance of no ADC signal.
