Initialization of CAMAC/VME

The ADC/TDC modules in the CAMAC or VME crate need to be initialized when the power is turned on.

VME initialization: 1. login babar (just type "babar" from dat2 machine). 2. You should be at ~/exp/????, ???? is the directory of the current experiment. Do "cd vsta" there. 3. - The VME modules can be initialized by "vmestat all.vsta", if you prepared "all.vsta". - The vsta file could be made by a perl script, makevsta.pl. In that case, run "vmeinit.sh". (This is the usual case.)
4. On the execution of vmestat, the LEDs on the modules should flash.

  • "makevsta.pl" overwrites "all_auto.vsta".
  • You can change the settings by editing the first part of "makevsta.pl".
  • \@modules...specify ADC/TDC, GEO number, and adress.
  • \@disable...You can specify unnecessary channels for each module.
  • $fsr...TDC's Free spectral range parameter. (See Baba-san's web page.)
  • $thres...Common ADC threshold (All channels become the same.) -vmeinit.sh is a shell script which call "makevsta.pl" and "vmestat all.vsta".

CAMAC initialization: 1. Login to dat. (It is not dat2 or babar!). Username is "rips", and the password is "o**". 2. Do "cd 3351_init". 3. Execute "init.sh". 4. Make sure the station no. etc. are correctly configured. 5. If if fails (it often fails), try the following: rerun the script, send "clear" by the switch at the CAMAC crate, turn off and on the crate,

Files: - generate_ccsta.pl... Perl script to generate ccsta file - gc_3351.ccsta, gc_3371.ccsta... ccsta files generated. - check.sh...script to check the configurations. - init.sh... shell-script to execute "ccstat" and "check.sh".
