Cabling done, signal checked, and top chamber closed

[Okutomi, Fujii, Shoda]

We did the cabling and the checked the signal.
Since all the signals are checked, the top chamber has been closed with suspension released.

1. Cabling
We connected the cable to the feedthroughs.
From the feedthroughs, we connected the D-sub cables to the circuits via flippers.
Note that the some flippers are not well connected.
We have got all the OSEM output and LVDT output from the fixed suspension.

2. Signal check
2-1. Traverser check
We checked the Traverser actuation with suspension fixed.They worked.
Also, since we have got the new script in order to chenge the velocity of the Traverser from Uraguchi-san@ATC, we tested it. They worked.

2-2. OSEM check
Release the suspension and see if the OSEM outputs seem to be OK.
One of the OSEM cable was happened to be mistaken to other OSEM connection, but it was fixed.
As far as we checked the OSEM signal waves, the suspension seems to be hanged freely.

2-3. motor check
We actuated the 3 picomotors and saw they working with the OSEM outputs.
Same for the fishing rod.

Suspension is living so far (except for the TM osem flag, as reported before).
