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. The it may be that one units has the internal clock active while the other spectrograph are using the multiplexor clock signal.

The fix is to see if the internal clock jumper is installed and remove it if so. (Add picture that shows how to locate the internal jumper.)
