We are cabling between the BS chamber and BS rack.
The reasons of re-cabling are
1. Electronics(Stepper motor, satellite box, pico motor driver, ...) were placed on the floor
2. Various length of D-sub cable are used and there were many D-sub D-sub connection
3. Too complicate cabling path (if we need the additional study, its complicatedness will make it difficult.)
4. Possible noise source of BS actuation
So we started the BS re-cabling.
1. Set the small electronics rack next to BS chamber.
2. Dis-connect all old cable.
3. Tagging to all connectors
4. Finalize the all cable path.
Next week,
1. Finalize the cabling
2. Connection test to motors
3. Suggestion to future cabling (SR2,SR3, SRM)
