<p class="MsoNormal">I am slightly concerned about the crate observations. We had no problem with the good crate during running and had the epics values available the whole run. The “bad” crate could not generate the epics pvs for the experiment and demonstrated
a very different behavior than the crate we used even when we swapped in different cards from other crates. The problem was not an issue with the cards, as we observed.

boards itself. We noticed that the EPICS PVs only were available when one board was connected at the time, regardless of the crate to which (crates .136 or .135) they were connected.<o:p></o:p></span></p>
