  1. What are we using 16 DAC channels for in the LSC?

For the new input and output tip-tilts.  Two input, two output, each requires four channels.

  1. What are the functions of those IOO DAC channels which go to cross-connects? If they're not properly sending, then we may have malfunctioning MC or MCWFS.

I have no idea.  I don't know what the hardware is, or is supposed to be, connected to.  DAC for WFS??  Was there at some point supposed to be fast output channels in the PSL?

Quote:
  1. Can we just use the SLOW DAC (4116) for the ALS PZTs? We used this for a long time for the input steering and it was OK (but not perfect).

 Probably. I'm not as familiar with that system.  I don't know what the availability of hardware channels is there.  I'll investigate tomorrow.
