HOWTO Use the DAQ System
The DAQ system is generally kept running on the clon03 display(s) in the Hall-B counting house. Check first if it is there before restarting it so you don't accidentally kill a run in progress. Killing the current DAQ processes:
To kill the current DAQ processes, ssh into the halldrun account on clonxt2 and type "kill_daq". This will kill most of the DAQ processes, but not all (e.g. the mini-SQL server is not killed).
Starting the DAQ from scratch:
To start the DAQ from scratch, ssh into the halldrun account on clonxt2 and type "start_daq". (Note that this will automatically run the kill_daq script first in order to remove any stray processes before starting fresh ones.) A number of new windows will open including: RunControl Server xterm (rcServer), Event Builder xterm (coda_eb), Event Recorder xterm (coda_er), CMLOG message browser, and RunControl GUI.
After the RunControl GUI window comes up:
- click on "Connect"
- click on "Configure"
- select the appropriate configuration and click "OK"
- click "Download"
- click "Start Run"
- click "End Run" whenever you are ready to end the run.
