A RFS LLRF controller is installed in the PIP-II IT SSR1 rack to allow
testing in parallel with the Fermilab LLRF system. The resonance control chassis
will be shared by the two systems.

#1 Updated by Philip Varghese 29 days ago

We have successfully configured one RCC for SSR1 in our lab area. There are still some error messages towards
the end of the process. However, we were able to ping its IP address from another controller behind the controls
firewall. The next step is for LBL to confirm they can connect to the chassis and help with the testing of the
QSFP communication channel between the SOC LLRF controller and the RCC.

#2 Updated by Shrividhyaa Sankar Raman 29 days ago

  • % Done changed from 20 to 40
  • The RCC has been configured today to the IP address
  • It can be pinged (tested in the lab from the HWR development system)
  • Sergio has also verified he is also able to reach the device from cmts-llrf-vm-server.
  • He has also successfully loaded the latest resonance control bitfile and tested the register interface - see below.


  • Establish the fiber link between the SOCMFC to the RCC, so that Sergio can confirm that the optical link is up by reading the 'rev_id' and other status registers and can do some data captures of whatever data you're sending from the SOCMFC.
