 In order to run the combined S800 + Gretina daq, the following steps need to be taken:
+  - Make sure 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.
   - [[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.
   - 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.

-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.
