    keyword=Delay module channel going bad ?

    Here is part of a mail I sent to Robert, I was a bit worried about the CAMAC module ( delay module between FAN and TDC ), it seemed to have went wrong already once because of high temperature. " http://www.jlab.org/~adaq/halog/html/0704_archive/070407015520.html

    it is not the first time it happens, I concluded it might have a problem with the module getting hot but I did have to fiddle with this ribbon cable so maybe I made the connection better. So I guess I made a wrong guess because of the coincidence with the AC off. "

    So if the cable removed could be checked, that the corresponding cable/channel is good the last culprit would be this delay module. I think we have spare for this one in the cabinet.

    I guess this can be checked at the next beam down/access since indeed this does not affect the trigger nor ADC but only this particular TDC channel.
