Error message at 15:38:48 on 6/25/13 said ER was not responding it seemed to recover but event number -vs- TDC had gaps for TDC ch 8-> 15, it looks like all the events came out in TDC ch 11 after the ER client recovered?, starting a new run

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?
