Summary:

There are several problems evident already.

1. Several EPICS database entries were missing. WTF.
2. After fixing the missing entries, the PMC could be locked. However, the IMC could not be locked.
3. I think the FSS Interface card is not configured correctly.

For now, I've returned the old c1psl connections, the PMC and IMC are both locked. Need to do some debugging on the bench.
