LRS2 and Virus (camra) Procedures

• Installing new spectrograph configuration files
  • When the spectrograph arrives on site, verify the spectrograph unit number and the controller number.
  • In your working copy of trunk, do svn up.
  • Check in the directory ./camra/etc/ to verify that the configuration files have been checked in. The files should be spectro-nnn.conf and cntl-mmm.conf where nnn is the spectrograph unit number and mmm is the controller number.
  • Look at the spectro-nnn.conf file and verify that the controller-id value matches the delivered controller.
  • Edit the file virus_server.conf,
    • Add spectro-nnn.conf to the list spectrograph-configs if it is not already in the list,
    • Add cntl-mmm.conf to the list controller-configs if it is not already in the list.
  • Commit the changes to virus_server.conf to the svn repository into trunk.
  • Install the new configurations in the operational directories,
    • Use the het_release script with the instruments_config target
    • I have a script in /home/liberty/jrf/HetDevel/jrfwork/doinstall that does this but you will have to change the user name for your account on hetdex-pr.as.utexas.edu.
    • The install process requires your password to run sudo during the installation process.
    • See DevelInstall for more information about the installation process.

• To clear out the ram disk on lrs2 or vdas
  • insure data directory in /hetdata has owner hetdex:hetdex and group write permission
  • run as hetdex on lrs2 or vdas $HET_SRC_ROOT/camra/testing/proxy-pivot-[virus|lrs2]-data.sh `find /mnt/camra_ramdisk/ -name "*.fits"`

• Reset the PCIe interface cards if
  • the ccd array failed during an exposure
  • if vdas hangs during reboots at the Initializing PCIe step

• Horizontal sync images If some or all of the virus images appear to have a horizontal sync problem. See attached image. The fix is to see if the internal clock jumper is installed and remove it if so.
