Local Emu DAQ Manual

1. Starting the DAQ farm
   1. Starting the logger
      1. Log on to slice@emuslice10.
      2. Type emuLogger
         The consol log messages will appear in this window. In parallel, a log file will also be written to emuslice10:/log/EmuDAQ.log
   2. Launching the executives for the first time
      1. Log on to slice@emuslice10.
      2. Type
         source emuPass
         if you haven't yet done so in this shell.
         You will be prompted for the pass phrase.
      3. Type
         emuFarmer -c http://emuslice10/slice/config/EmuConfig.xml -a status
         to see if any forgotten, leftover processes are running.
         If so, stop them by
         emuFarmer -c http://emuslice10/slice/config/EmuConfig.xml -a stop
         If all clear, start the farm by
         emuFarmer -c http://emuslice10/slice/config/EmuConfig.xml -a start
   3. Relaunching the executives
      1. Type
         emuFarmer -c http://emuslice10/slice/config/EmuConfig.xml -a restart
         (No need to get the pass phrase if emuFarmer is issued in the same shell as it has been before.)
2. Running
