KCOR COMMENT BY berkey: Fri May 15 00:01:09 GMT 2026
The new KCor dark shutter was tested for functionality.

- Power supply and controller have been installed in the AUX nema box
-Shutter was temporarily connected to the cabling in the instrument box for end to end functional testing, with the NI Max test panel.  Shutter acted as expected.
-The shutter was then removed form the instrument box. And cabling restored to drive the old parker shutter.
-The new shutter power supply was then unplugged form the distrubtion switch in the AUX nema box.

Kcor hardware was then tested to verify functionally of the camera, modulator and mechanisms  control systems.  Socketcam was allowed to collect 2 or 3 images. (note the end of day and data log script was not run before powering down the computer.  But the data was marked as testing and the dome was closed so it will not be powered back on for the transfer.

To-do before switching over to the new shutter.
-Update the the software to trigger and get feedback from the new system.
-Swing the CD-217 cable from the MC4u nema box to the DB-25 plug in the AUX box
-Remove the parker shutters from the instrument, and install the new uniblitz shutter
