 ====== 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.
-  - Makesure that the external synchronization and external clock are enabled in the S800 ULM trigger module. Edit file **CC0105Begin.tcl** in directory **/user/s800/converged_daq/Scripts**, and set the values of the variables **extsynch** and **extclock** to 1.
+  - 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.)
-  - [[S800 DAQ tools#Running the S800 DAQ|Run the S800 ReadoutGUI]] for the S800 data acquisition system as you normally would on spdaq19, and click the ''Start'' button.
+  - Make sure that GRETINA DAQ is ready.
-  - Log in using the experimental account to **ddasdaq3** or any other of the systems dual homed to the GRETINA/NSCLDAQ network.
+  - 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 (as of March 2016, 11.0-020). If everything has started correctly you should have the following ring buffers in the dual homed system (e.g. ddasdaq3):
+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):
   * **experimental-user-name (e.g. e14045)**: This ring is where sampled coincidence data is placed.  This is done via a tapcat, glom pipeline.
-  * **spdaq19.rawccusb**: It will provide raw data from the S800 CAMAC crate.
+  * **spdaqXX.rawccusb**: It will provide raw data from the S800 CAMAC crate.
-  * **spdaq19.rawvmusb**: It will provide raw data from the S800 VME crate.
+  * **spdaqXX.rawvmusb**: It will provide raw data from the S800 VME crate.
-  * **spdaq19.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.
+  * **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.
 In addition to the normal **stagearea** structure in the experiment account, three directories are added that will be used to store raw S800 data:
