FRS 6114

Late entry for work done yesterday 10/4/2016.

FRS 6114 reports offset of 4000 counts in some of the fast I monitor channels. The AA chassis associated with these channels were powered off, no change in offset. Here is a list of the things we did.

1. The ribbon cables between the ADC card and the interface card were replaced on cards 1 and 2.
2. All ADC cards and interface cards were reseated.
3. IO SUSAUXEY was restarted, after ribbon cable swap and again after reseating the cards.

As of now, ADC1, ch19 still has an offset of ~4000 counts.

One thing to note, the adapter cards do not line up with the mounting hole screw. When the mounting screw is inserted, it lifts the back of the card up. This is something we have seen before. For now, I left the adapter cards without the mounting screw inserted.
