-==== Running in Slave mode with multilogger ====
+==== Readout GUI ====
 The S800 Readout GUI is invoked by either clicking the icon **S800 DAQ** in the desktop of [[Software#u6pc5 (data U6)|u6pc5]] or by navigating in a Linux terminal to the directory **/user/s800/converged_daq** and typing ''godaq''. The Readout GUI window will appear with three tags labeled "main", "SSHPipe@localhost:0", and "SSHPipe@localhost:1". The first one provides general information about the ReadoutGUI. The second and third tabs provide information about the data sources (from the CCUSB and VMUSB controllers). **IMPORTANT NOTE:** When running Readout GUI, make sure that the environment variables needed by the system are properly defined. This can be done from a Linux session connected to spdaq19 by typing: ''. /usr/opt/nscldaq/xxxx/daqsetup.bash'', where ''xxxx'' is the nscldaq version (xxx = 11.0-020, on Feb 2016).

+==== 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 an external clock signal and external synchronization from the master DAQ. Running in Slave mode requires to change the script **CC0105Begin.tcl** in directory **/user/s800/converged_daq/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.
