- +  ​- [[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. ​   
-  ​- [[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 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.) 
-  - Log in using the experimental account to **ddasdaq3** or any other of the systems dual homed to the GRETINA/​NSCLDAQ network.+  - 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.   - Use command ''​godaq''​ to run the Readout control program.
