 ====== How to run combined S800 + GRETINA ======
 In order to run the combined S800 + Gretina daq, the following steps need to be taken:
+  - [[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.
+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):
--  Start up the S800 data acquisition system as you normally would on spdaq19.
+  * **experimental-user-name (e.g. e14045)**: This ring is where sampled coincidence data is placed.  This is done via a tapcat, glom pipeline.
--  Log in using the experimental account to ddasdaq3 or any other of the systems
+  * **spdaqXX.rawccusb**: It will provide raw data from the S800 CAMAC crate.
-   dual homed to the GRETINA/NSCLDAQ network.
+  * **spdaqXX.rawvmusb**: It will provide raw data from the S800 VME crate.
--  godaq starts the Readout control program.
+  * **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.
--  Click the Start button.  This will grab remote control over the S800 readout GUI.
-   You should now be able to start runs as needed in the experiment's ReadoutGUI running
-   on the dual homed system.
-When everything has started correctly you should have the following ring buffers
+In addition to the normal **stagearea** structure in the experiment account, three directories are added that will be used to store raw S800 data:
-in the dual homed system (e.g. ddasdaq3):
-*  experimental-user-name  (e.g. e14045) this ring is where sampled coincidence data
+  * **~/stagearea/rawccusb**: Event files containing raw CCUSB data from the S800.
-   is placed.  This is done via a tapcat, glom pipeline.
+  * **~/stagearea/rawvmusb**: Event files containing raw VMUSB data from the S800.
-*  spdaq19.rawccusb - will provide raw data from the S800 CAMAC crate.
+  * **~/stagearea/s800filter**: Event files containing event build, reformatted S800 data from the S800 Filter.
-*  spdaq19.rawvmusb - will provide raw data from the S800 VME crate.
-*  spdaq19.s800filter - will provide the event built, reformated data from the
-                       S800. During a run, data are pushed from this ring into the
-                       GRETINA GEB.
-In addition to the normal stagea are structure three directories are added that will
-be used to store raw S800 data:
-*  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.
-. On spdaq48 in /user/s800/operations/daq/usb/TclXXUSB do:
-**wish ./RunControl.tcl**
-or, on devop2 (the S800 MAC machine)
-click on the operations folder on the lower icon bar and select runcontrol.command
-. On a dataU machine logged in as the experimental account (e11007 for the June 2012 testing period) do
-**godaq**
-. On spdaq44 do:
-**/usr/opt/daq/10.1/bin/ringbuffer status**. The output should look similar to:
-<code>

-Upon start of run there will be another client of the s800 ring, which is the pushToGEB process. This should die on end run.
-The S800 daq will now be in slave mode, and run control is done from the NSCL daq window.
