Appolo Team installed the feedthrough on HAM6 for the ISC fast shutter and the feedthrough emulator.
The fast shutter was tested with a DC power supply and it was confirmed the shutter mirror popped up.

Since the prepared feedthrough has the form factor of 2.75" CF, a zero-length adapter 2.75"-4.5" was inserted (great thanks to Gerado and John).

Once the feedthrough was installed, the in-vac shutter cable was connected to the feedthrough.
Then the shutter connection was tested by giving some current. With a current of 50mA, I could confirm that the shutter mirror popped up with this current.
At CIT we tested the shutter at 150mA in a vacuum pressure and it survived. So as long as we don't exceed this current, the shutter coil is completely safe.

The viewport emulator was also installed on the North door flange.
The heights of the emulation rings, particularly the east-most one which was moving, should be confirmed and adjusted.
