 +  - [[S800 DAQ tools#Running the S800 DAQ|Run the S800 ReadoutGUI]] for the S800 data acquisition system as you normally would on the S800 spdaqXX (note, at present X=50), and click the ''Start'' button.   
 +  - Make sure that the external synchronization and external clock are enabled in the S800 ULM trigger module. (Just click on the corresponding "check boxes" in the ULM GUI.)
 +  - Make sure that GRETINA DAQ is ready.
 +  - Using one of the dataU6 Linux boxes (e.g. u6pc2) Log in using the experimental account to **ddasdaq3** or any other of the systems dual homed to the GRETINA/NSCLDAQ network.
 +  - Use command ''godaq'' to run the Readout control program.
 +  - Click the ''Start'' button.  This will grab remote control over the S800 Readout GUI. The S800 daq will now be in slave mode.
 +  - You should now be able to start runs as needed in the experiment's ReadoutGUI running on the dual homed system.
  
-1. On spdaq48 in /user/s800/operations/daq/usb/TclXXUSB do: +You can check the ring buffers using the command **/usr/opt/nscldaq/xxxxx/bin/ringbuffer status**, where xxxxx is the nscldaq version. If everything has started correctly you should have the following ring buffers in the dual homed system (e.g. ddasdaq3):
- +
-**wish ./RunControl.tcl** +
- +
-or, on devop2 (the S800 MAC machine) +
- +
-click on the operations folder on the lower icon bar and select runcontrol.command +
- +
-2. On a dataU machine logged in as the experimental account (e11007 for the June 2012 testing period) do +
- +
-**godaq** +
- +
-3. On spdaq44 do: +
  
-**/usr/opt/daq/10.1/bin/ringbuffer status**. The output should look similar to:+  * **experimental-user-name (e.g. e14045)**: This ring is where sampled coincidence data is placed.  This is done via a tapcat, glom pipeline. 
 +  * **spdaqXX.rawccusb**: It will provide raw data from the S800 CAMAC crate. 
 +  * **spdaqXX.rawvmusb**: It will provide raw data from the S800 VME crate. 
 +  * **spdaqXX.s800filter**: It will provide the event built, reformated data from the S800 Filter. During a run, data are pushed from this ring into the GRETINA GEB.
  
-<code> +In addition to the normal **stagearea** structure in the experiment account, three directories are added that will be used to store raw S800 data:

-Upon start of run there will be another client of the s800 ring, which is the pushToGEB process. This should die on end run.+  * **~/stagearea/rawccusb**: Event files containing raw CCUSB data from the S800. 
 +  * **~/stagearea/rawvmusb**: Event files containing raw VMUSB data from the S800. 
 +  * **~/stagearea/s800filter**: Event files containing event build, reformatted S800 data from the S800 Filter.
  
  
-The S800 daq will now be in slave mode, and run control is done from the NSCL daq window.
