ETMY camera moved to h1digivideo3
WP 11315. Dave, Erik, Patrick The ETMY camera has been moved from h1digivideo2 to the new code running on h1digivideo3. Note that the cameras running on this code (all those on h1digivideo3) have an additional channel: {channel_prefix}VALID: 1 if and only if there has been a successful iteration through the image grab loop and the last iteration through the image grab loop succeeded. (read only) Monitoring this channel should be a better way to check for image freezes than monitoring the centroid positions. The full list of channels is in the wiki. Erik has updated the script that starts the camera client on the control room wall screens. Dave is updating the DAQ.
After the change of ETMY camera server, the sign of camera servo PIT3, which uses the ETMY camera, seems flipped. I changed the PIT3 gain from 300 to -400 in lscparams.
