ETMx ISI balancing started

GregG, JimW

After SUS, et al. finished locking the ETMx optic, Greg and I went to the end station to work on balancing the ISI and route some cables. We first uncovered the ISI and finished routing the various cables that have been added since the TMS was mounted (still have the ESD cable to route, I forgot it was up there ...). After doing a "feel" test of the lockers to make sure our payload wasn't way off, we unlocked stage 2 the ISI. When I went to look at the CPS signals in dataviewer I saw we had problems. One possible dead CPS (maybe just railed, the lockers on St2 let you do that) , and one entire corner (4 sensors) that is just reading electronic noise at ~1 ct. Hopefully the dead conrner just means I forgot to turn something on. Preliminary spectra on everything look good, so no show-stoppers so far. Too late today to fix everything, so we'll come back to it on Monday.
