 In order to run the combined S800 + Gretina daq, the following steps need to be taken: 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 buildreformatted S800 data from the S800 Filter.
- ​spdaq19.rawvmusb ​- will provide ​raw data from the S800 VME crate+
- ​spdaq19.s800filter ​- will provide the event builtreformated ​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.

-1. 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

-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:

-The S800 daq will now be in slave mode, and run control is done from the NSCL daq window.
