WP11393 Add fast Cosmic Ray channels to DAQ

Ray Frey, Robert Schofield, Marc Pirello, Dave:

A new h1pemcs model was installed, which corrects a naming error with the photomultiplier tube test points and adds them to the DAQ at the full 16kHz rate. DAQ restart was required.

WP11387 NONsens changed to h1oaf and h1bos models

Jenne, Dave:

New h1oaf and h1bos models were installed, no DAQ restart was needed.

WP11391 DAQ Frame Writers storing frame file MD5 checksums

Jonathan, Dave:

Jonathan reconfigured the frame writers, via puppet, to store the MD5 checksum for all gwf files written. DAQ restart was required.

Adding New Digivideo Saturated EPICS Channels to the DAQ

Patrick, Dave:

Patrick made an EPICS IOC change to the new video server, which created a SATURATED channel for each camera. I modified the script which generates H1EPICS_DIGVID.ini to add these channels to the DAQ. DAQ restart was required.

DAQ Restart

Jonathan, Dave:

The DAQ and the EDC were restarted for the above tasks. As was seen before, FW0 spontaneously restarted soon after it got running. In this case after it had only written one full frame file, and before we got a chance to start FW1.

Also as before, both GDS0 and GDS1 needed a second restart to sync up their channel lists.
