+ | ==== Running in Slave mode with multilogger ==== | ||
+ | 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 | ||
+ | |||
+ | |||
+ | 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 '' | ||
+ | |||
+ | 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: | ||
+ | |||
+ | * Click to the tab '' | ||

+ | * Click again on the tab '' | ||
