[Ian, Koji] - Activity on 25th (Fri)

We continued working on the ETMY electronics replacement.

- The units were fixed on the rack along with the rack plan.

- Unnecessary Eurocard modules were removed from the crate.

- Unnecessary IDC cables and the sat amp were removed from the wiring chain. The side cross-connects became obsolete and they also were removed.

- A 18V DC power strip was attached to one of the side DIN rails.

Warning:

- Right now the ETMY suspension is free and not damped. We are relying on the EQ stops.

Next things to do:

- Layout the coil driving cables from the vacuum feedthru to the sat amp (2x D2100675-01 30ft ) [40m wiki]

- Layout DB cables between the units

- Layout the DC power cables from the power strip to the units

- Reassign ADC/DAC channels in the iscey model.

- Recover the optic damping

- Measure the change of the PD gains and the actuator gains.
