Subject: c1ioo now on Dolphin network 

The c1ioo host is now fully on the dolphin network!

After the mx stream issue from two weeks ago was resolved and determined to not be due to the introduction of dolphin on c1ioo, I went ahead and re-installed the dolphin host adapter card on c1ioo.  The Dolphin network configurations changes I made during the first attempt (see previous log in thread) were still in place.  Once I rebooted the c1ioo machine, everything came up fine:

We then tested the interface by making a cdsIPCx-PCIE connection between the c1ioo/c1als model and the c1lsc/c1lsc model for the ALS-X beat note fine phase signal.  We then locked both ALS X and Y, and compared the signals against the existing ALS-Y beat note phase connection that passes through c1sus/c1rfm via an RFM IPC:

The signal is perfectly coherent and we've gained ~25 degrees of phase at 1kHz.  EricQ calculates that the delay for this signal has changed from:

122 us -> 61 us 

I then went ahead and made the needed modifications for ALS-Y as well, and removed ALS->LSC stuff in the c1rfm model.

Next up: move the RFM card from the c1sus machine to the c1lsc machine, and eliminate c1sus/c1rfm model entirely.
