What this means:
- We definitely have enough DACs for the ALS PZTs. The free channels are also in the right places: at the end stations and in the c1ioo FE, which is close to the PSL and hosts the c1als controller.
- We appear to have enough ADCs for the QPD in c1ioo.
- We don't have any available DAC outputs in c1lsc for the Fibox. If we can move the Fibox to the IOO racks (1X1, 1X2) then we could send LSC channels to c1ioo and use c1ioo's extra DAC channels.
Of course we'll have to investigate the AA/AI situation as well. I'll try to asses that in a follow up post.

It looks like we have spare channels in the AA chassis for the existing c1ioo ADC inputs to accommodate the POP QPD. 
We need AI interfaces for the ALS PZTs. What we ideally need is 3x D000186, which are the eurocard AI boards that have the flat IDC input connects that can come straight from the DAC break-out interfaces. I'm not finding any in the spares in the spare electronics shelves, though.  If we can't find any we'll have to make our own AI interfaces. |
