We couldn't see the thermistors after connecting the in-vac sqz cables. Investigating, we found that the signals can be found on cable 303 rather than 304 at the sqz satellite chassis; and the PZTs seem to show up on cable 304 rather than 303. The DCPDs show up as expected on 305. As a side note, we noticed that for DCPD2 the case is connected to the anode, where this is not true for DCPD1. The sqz satellite chassis seems to short the case to the cathode, so this looks like an unwanted short.
We traced the cables to the vacuum flange and found them to be connected correctly, indicating that they are swapped in the chamber. Taking a look inside, we couldn't figure out how relate the cable harness routing described in D1300122 with what is installed. We gave up and left the cables disconnected at the satellite chassis.
Hugh and I went in and checked each cable down from the flange and the short seems to be either in the DCPD2 box or the cable leading out of it. I left the 9pin cable bracket unplugged until we have an idea what to do with this.
While I was in there I also swapped the two cables that connected to D1700439 & D1700438 (Termistors and PZTs).
