4165 7/3/13 58 mv Threshold, S:F:G=1400:-700:509 , ADB cards were swapped to see if the out of time events in TDC ch 40->43 move to the channels in the other ADC, they did not, switch the cables back and check the ADC cables.
4166 7/5/13 58 mv Threshold, S:F:G=1400:-700:509 , swapped the ADB output cables such that ADB outputs in TDC chan 32->47 are now going into TDC channels 81->96. The problems with ut of time hits moved with the ADC output cables. The question now; Is it the cable, the connectors, or the TDC?
