First steps in Data-Aquisition

• Connecting to a DAQ-Host

  At the moment we have two data acquisistion hosts; a CVC and an E7. The IP-name of the CVC is CVC8, of the E7 is E7KP3A. The CVC has also two LAT-servicenames: CVCKP3A and CVCKP3B. Use TELNET or LAT to connect to the hosts

  Example:

  telnet e7kp3a 
  
  set host /lat cvckp3a 

  Try it ! Telnet to E7

  !!! Attention !!! Be sure that you do not disturb running data acquisistions! The memory resources on the CVC are low !

• Username for data-acquisistion purposes is ALADIN with the default KP3 password. (If you don't know it up to now, ask Volker Serfling)

• Change into the desired directory with the command

  cd s117_light

• Start the message logger with the command

  msg_log &
  

  If you get the message

  CVC8 aladin (3) Found active message logger with pid 9 !
  Cannot compete. Leave. Bye, bye

  Don't care; the message logger is already running!

• Start the SingleBranchSystem with the command

  sbs

  @start
  

• Now the system is ready to take data.
• Start the data acquisistion with

  start ac
  

• Stop the data acquisition with
