We have connected the BS oplev QPD to PR3 rack. We have also started a new real time model k1visbs which will be used for the BS suspension on K1PR2 machine.
There was an issue on IPC, so we couldn't see the QPD signal in the BS model. We will fix this later (maybe tomorrow).

What we did
1. Installed viewports for BS oplev and camera, as explained in klog #875.

2. Connected the BS oplev QPD (SN 44) and Universal Whitening Filter with DC Power Chassis at PR3 rack(K1PR0 machine rack) with Dsub 15pin 20m+10m cable. We had to use this rack since we only have 5 whitening filter chassis and we have to share them with other QPD. The situation is similar as IMMT1T DC QPD (see klog #862).

  * The BS oplev QPD is currently not fixed on the pylon breadboard yet (see klog #877).

3. Connected Universal Whitening Filter with DC Power Chassis and Anti-aliasing filter with Dsub 9 pin 1 m cable. (See photo attached for cabling)

4. Made a new model k1visbs.mdl and started this on K1PR2 machine. This model has DCU ID = 96, and the specific cpu = 4. We had to run this BS model on K1PR2 since we don't have BS rack for iKAGRA. So, this is a temporary solution.

5. Modified k1vispr3 model so that the QPD signals from K1PR3 machine is sent to k1visbs running on K1PR2 machine via IPC. I also modified k1lsc model so that the LSC signal can be sent to the BS model. I restarted k1vispr3 model, k1lsc model, and k1visbs models. Some how, IPC showed errors, so currently QPD signal cannot be seen at k1visbs. We are not sure what is the reason.

  * In order to restart k1visbs model, I had to chmod 755 * at /opt/rtcds/kamioka/k1/target/k1visbs/k1visbsepics/burt directory. This is to stop burt-ing during restarts which result in timed out.

6. Fixed MEDM screens for the BS suspension (Type-C) accordingly. (Sorry I messed up the button/screen sizes. I will fix it later.)

7. Schematic can be found in the attached diagram.
