-The S800 DAQ can be run in Standalone mode (as described above), or in Slave mode. The later means that the S800 DAQ is controlled by an external DAQ (e.g. GRETINA). In this mode, the S800 ULM receives external clock and external synchronization  signals from the master DAQ. Running in Slave mode requires to change the script **CC0105Begin.tcl** in directory **/user/s800/s800daq/Scripts**. In this file, there are two variables ''extsynch'' and ''extclock'' to define if the external synchronization and clock signals are enabled (=1) or disabled (=0). Make sure that you set these variables to 1 if you want to run in Slave mode.+The S800 DAQ can be run in Standalone mode (as described above), or in Slave mode.

-By default, when running in Slave mode, data are recorded in the stagearea of the Master DAQ (experiment account). It is however possible to record simultaneously data from the S800 into the S800 stagearea, using the ''multilogger'' option (see ReadoutGUI figure above). The S800 ReadougGUI offers the possibility to record data from four different S800 ring-buffers: rawccusb, rawvmusb, s800built, and s800filter. The later is the most important since data from this ring buffer can be immediately processed by the S800 SpecTcl. +By default, when running in Slave mode, data are recorded in the stagearea of the Master DAQ (experiment account).

 When running XDT for an experiment with a Master DAQ (e.g. GRETINA), it is recommendable to run the S800 DAQ in Slave mode with the s800filter multilogger enabled. This can be done following the steps: When running XDT for an experiment with a Master DAQ (e.g. GRETINA), it is recommendable to run the S800 DAQ in Slave mode with the s800filter multilogger enabled.
