  * Mark updated the BS circuit diagram [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=3600|D1503600]]:
   * Added information on the binary IO.
   * Renamed channels to conform to Okutomi-kun's new scheme.
   * Made the ADC/DAC channel assignment consistent and more logical.
   * Updated the stepper motor sections with info about the new driver chassis.
  * Mark and Hirata-san worked on collecting parts and tools that will be needed for cabling of the BS next week. (11 special-purpose cables need to be made for the picos/steppers/OSEMs/LVDT on the RM/IRM/IM/BF and, time permitting, 2 more for the SF.)		   * Mark and Hirata-san at Mitaka
   * Gathered parts for cable making.
  * Mark and Hirata-san at Kamioka:
   * Replaced the floor panels that had been taken from the PR2 area (filling in the hole in the floor) and found/installed two new panels to act as bridges near the BS assembly frame.
   * Installed two more LPCDs and the stepper motor driver in the PR2 rack.
   * Ran cables from the rack to the second and third sat amps (for the IRM OSEMs).
   * Added a second DIO card in the rack and connected it to the BIO inputs and outputs of the new LPCDs.
   * Started making extension cables for RM-H2 and -H3 OSEMs but gave up due to complicated grounding arrangement.
   * Washed four 40-cm D-Sub-9 ribbon cables to use as temporary extensions (maybe also for H1/H4).
   * Added extension to the IM pico cable for the BF yaw pico.
   * Made LVDT adapter cable.

  * Mark updated the installation procedure with lessons learned from the last few weeks.
  * Mark downloaded Hirata-san's Inventor model of the BS in the tank and starting thinking about installation of the suspension and lower bread board.
