Preparation for TMSX optics installation part2

[K. Nagano, K. Tanaka, N. Fujii, Akutsu]

(This is a report about work on Sep. 21st.)
Continuing from Sep. 20th (klog6217), we continued to prepare for TMSX installation.
Note that, in parallel with the following work, Akutsu-san worked to fix TMSX-VIS although that work is not reported in this entry.

# What we did
## Some parts transportation and unpacking
We received some ordered parts from company.
We brought them to X-end and unpack and wiped them.
Optics were stored in the desiccator (figs. 1-4) and mechanical parts were put on the metal rack (figs. 5-6) in TMSX clean booth.
Optics stored in the desiccator are listed below,
  * PLCX-50.8-180.3-UV-1064, one (GPT IR lens1),
  * PLCC-25.4-64.4-UV-1064, one (GPT IR lens2),
  * 10Q20HBS.33S, six (GPT IR BS) @,
  * NE205B, NE210B, NENIR210B, NENIR220B, two each (GPT ND filter) @,
  * LA1380-A-ML, two (GPT GR lens1) @, * BSW41-532, six (GPT GR BS) @,
  * TFM-25C050532, one (GPT GR steering mirror (1 inch)) @$,
  * TFM-50C080532, eight (GPT GR steering mirror (2inch)) @,
  * TFA-25C05-10, three (GPT GR steering mirror (1inch)) @%,
  * SLB-50.8-200NM, one (BRT lens3),
  * TFMQSP-50.8C10-20-532/1064-0/26D, two (BRT steering mirror),
  * HBSY21, one (BRT Harmonic BS),
where @, $, and % indicate that they used in TMSX and TMXY, they are not delivered partially (the rest will be delivered on Oct. 3rd), and they are used temporally instead of not delivered things.
The mechanical parts were explained in JGW-T1808962.

## Electronics installation
We installed following electronics from the top of the rack (in bracket S-number is shown) (figs. 7-11).
  * Two high power coil drivers (6242, 6243) which were moved from ETMY (CRY) thanks to Miyamoto-san,
  * LVDT driver (7787) which were brought from NAOJ, Mitaka,
  * BNC-Dsub converter (ADC) (8806),
  * Three whitening filter chassises (8652, 8653, 8654),
  * Five Out Config Boards (not installed yet, 5429, 5440, 7683, 7687, 7689).
We updated information on JGWdoc and Coil Driver wiki (Place Of Coil Driver).
Note that cabling was not done.

## ADC and DAC check
We checked which ports can be used for TMSX in EX0 rack.
As a result, we confirmed that 0-31ch in ADC2 and 23-15ch in ADC0 and 12-15ch in DAC0 could be used.
For TMSX, 48ch for ADC and 8ch(?) are assigned for TMSX and 12ch for ADC and 4ch for DAC are still missing.

# Next step
* Cabling
* RT model preparation
* Get IR steering mirrors
