We have installed IMMT1T (IMMT1 transmission) DC QPD.
QPD output can now be monitored from the MEDM screen (not calibrated yet).
We have also put a camera on the pylon breadboard, but cables are not connected yet.
What we did
1. Put an extension breadboard (Thorlabs MB2530/M) on the IMMT1T pylon breadboard, and fixed a DC QPD and a camera. Fixed the pylon to the floor.
2. Connected DC QPD and Universal Whitening Filter with DC Power Chassis (JGW-D1302087) at MC rack with Dsub 15 pin 20 m cable. The cable was stored at the rack near MCE-MCF duct, and it is now stored near PR area clean booth.
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. Modified k1vismce model and k1lsc model so that the QPD signals from K1IMC0 machine is sent to k1lsc running on K1IOO machine via IPC.
5. Made MEDM screen LSC_CUST_QPD.adl and related screens for ISC QPDs.
6. Schematic can be found in the attached diagram.

We have also deleted IPC links and connected K1IMC0 rack and K1IOO rack with Dsub 9 pin 20 m cable (see klog #914 for why).
The IMMT1T QPD is now powered and whitening-filtered (filter not on yet) at K1IMC0 rack, but ADC-ed at K1IOO rack (ADC 0 IN 9-12).
Attached is the modified diagram.
