== Task list ==
{{{#!wiki green/solid
Note: some of the tasks can be done in parallel.
}}}
 * --(Place/install the WAB suspension)--
 * --(Align the position of WAB -> take WAB back to nominal position, put off protectors))--
  * --(horizontal alignment)--
  * --(yaw alignment)--
 * --(Move it to the saving mode.)--
 * --(Back to the nominal position.)--
 * --(Attach heat links)--
  * --(4 soft heat links to WAB)--
  * --(1 heat link btwn the top and the structure)--
 * --(Attach 2 thermometers)--
 * Set revised blocks under the base plate.

== Pin Assignment ==
P23, to be connected to Cryocon#7 E and F in this order respectively.
||Pin Name||Resistance|| Equipment  || Assign || Comment1  || Comment2 || Connection ||
||A||75 ohm|| Thermometer S/N#2564|| V- || Green || WAB ||  ||
||B||75 ohm|| Thermometer S/N#2564|| V+ || Black || WAB ||   ||
||C||4 ohm|| Thermometer S/N#2564|| I- || Red || WAB ||  ||
||D||4 ohm|| Thermometer S/N#2564|| I+ || Yellow || WAB ||  ||
||E||75 ohm|| Thermometer S/N#360|| V- || Green || Structure ||  ||
||F||75 ohm|| Thermometer S/N#360|| V+ || Black || Structure ||  ||
||G||4 ohm|| Thermometer S/N#360|| I- || Red || Structure ||  ||
||H||4 ohm|| Thermometer S/N#360|| I+ || Yellow || Structure ||  ||

Note that the pin arrangement (or the ''naming'') is mirrored compared with that of in IXC! Rather, I guess this IXC's would be correct.
