Local Emu DAQ Manual

1. Starting the DAQ farm

   1. Starting the logger
      1. Log on to cscdaq@emudaq.
      2. Type emuLogger
         The consol log messages will appear in this window. In parallel, a log file will also be written to emudaq:/data/local/EmuDAQ.log
   2. Launching the executives for the first time
      1. Log on to cscdaq@emudaq.
      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 -a status
         to see if any forgotten, leftover processes are running. (Troubleshooting.)
         If so, stop them by
         emuFarmer -a stop
         If all clear, start the farm by
         emuFarmer -a start
   3. Relaunching the executives
      1. Type
         emuFarmer -a restart
         (No need to get the pass phrase if emuFarmer is issued in the same shell as it has been before.)

2. Starting the DQM farm

   1. Launching the executives for the first time
      1. Log on to cscdaq@emudaq, if you haven't yet done so.
      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 -t dqm -a status
         to see if any forgotten, leftover processes are running. (Troubleshooting.)
         If so, stop them by
         emuFarmer -u cscdqm -t dqm -a stop
         If all clear, start the farm by
         emuFarmer -u cscdqm -t dqm -a start
   2. Relaunching the executives
      1. Type
         emuFarmer -u cscdqm -t dqm -a restart
         (No need to get the pass phrase if emuFarmer is issued in the same shell as it has been before.)

3. Run control

   1. Go to the local DAQ page. It shows the state of the DAQ and the online DQM. (Troubleshooting.)
   2. Click on Ctrl in the upper right corner. It lands you on the control page.
   3. If all applications are red (in 'Halted' state), select

      run number	your birthday
      run type	Monitor
      maximum number of events	-1
      build events	unchecked

      and click on Configure. The run number should be marked 'booked'. (Troubleshooting.) The DAQ and DQM applications should all turn yellow ('Ready'). (Troubleshooting.)
   4. Start taking data by clicking on Start. The DAQ and DQM applications should all turn green ('Enabled'). (Troubleshooting.) If we get trigger, the EmuRUI counters should start incrementing. (Troubleshooting.)
   5. Stop the run by clicking on Stop. The DAQ and DQM applications should all turn red ('Halted'). (Troubleshooting.)
