keyword=Chamber2 U13 follow-upThere was still a problem -- the U13 signals look the same as they did with the original cosmics run (see referenced halog entry).
I traced the ribbon cable from the A/D card at U13 over to the level translator panel and confirmed it was good. I double checked the labels on the cable that runs from the level translator to the TDC and they appear correct (but I did not test the physical cable).
Here is the cable run:
Chamber2 (U13) -> Level translator IN (cable labelled 13-4T) : Level translator OUT (cable 2U13L) -> TDC slot 20, ch 64--79 (cable labelled 2U13F)
I elected to replace the A/D card at U13 with a brand new one. The previous card was labelled "Damaged?" and put in the cabinet. Run 3107 (cosmics) was started with the new card in place.
