In randomly looking at site 12, I noticed that the CSAT wasn't coming in. I tried cycling power with eio 5 0/1 and even a ddn/dup, to no avail. I wondered if the Gill, still wired to port 4, could generate enough spurious interrupts to cause data from port 5 to stop. Thus, I changed the vertex.xml to look for Gill data on port 6 (like we did on station 8) and then rebooted the entire station. It came back up and now the CSAT is there. I don't know how long it had been down – clearly it was up when I did my "Quickie status" on Saturday.
