| 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 terminal by typing: ''. /usr/opt/nscldaq/xxxx/daqsetup.bash'', where ''xxxx'' is the nscldaq version (xxx = 11.0-020, on Feb 2016). | 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''.

| Before beginning taking data is necessary to initialize the system. This is done by clicking ''Start'' in the ReadoutGUI. You can inspect the status of each source during their initialization by clicking in one of the tabs "SSHPipe@localhost:0" or "SSHPipe@localhost:1". You will see a series of messages about the different initialization steps. The last message should be "Done". During the initialization process, a fourth tab labeled "ActionFilter" will appear with information from the S800 filter. Sometimes, you may see a warning message about an old "still-running" S800 filter session being killed. That's ok. | Before beginning taking data is necessary to initialize the system.

| After initializing the contollers, the ReadoutGUI window will show the ''Begin'' button active. In addition, three additional buttons should appear at the end of the window. They can be used to start the GUI associated with the [[#Mesytec CFD GUI|MCFD]], [[#Delay Window|Delay XLM]], and [[#Trigger GUI|Trigger ULM]] modules. Make sure that the system is completely initializing before opening those GUIs. | After initializing the contollers, the ReadoutGUI window will show the ''Begin'' button active.

| The figure below shows the Readout GUI window after initializing the system. After clicking ''Begin'', the "Event Builder" window will pop out, displaying information about the Readout session. Data can be recorded on disk by checking out the box ''Record''. To end a data run, simply click ''End''. | The figure below shows the Readout GUI window after initializing the system.

| The S800 electronics includes a Mesytec CFD (MCFD), used to "filter" the detector signals going to the Scaler and Mesytec TDC. The configuration parameters of the CFD (thresholds, delays, fraction, etc.) can be remotely adjusted via a MCFD GUI developed by the NSCL DAQ group. During tuning of the S800, one typically needs to adjust thresholds only. | The S800 electronics includes a Mesytec CFD (MCFD), used to "filter" the detector signals going to the Scaler and Mesytec TDC.

| The MCFD GUI is invoked by either clicking the icon **MCFD GUI** in the desktop of [[Software#u6pc5 (data U6)|u6pc5]] or by navigating in a Linux terminal and typing ''$DAQBIN/MCFDControl16 --protocol usb --serialfile /dev/ttyUSB0''. The environment variable DAQBIN is defined by sourcing the **daqsetup.bash** file in directory **/usr/opt/nscldaq/xxxx/bin**, where xxxx is the nscldaq version number (11.0-015 on Oct 26, 2015). | The MCFD GUI can be started in three different ways: 1) by clicking the button ''Launch MCFD GUI'' in [[#Readout GUI|ReadoutGUI]]; 2) by clicking the icon **MCFD GUI** in the desktop of [[Software#u6pc5 (data U6)|u6pc5]]; 3) by navigating in a Linux terminal and typing ''$DAQBIN/MCFDControl16 --protocol usb --serialfile /dev/ttyUSB0''.

| Sometimes, particularly if the previous S800 DAQ session ended in an uncontrolled way, there may be old processes running (CCUSB and/or VMUSB and/or S800 event builder) that will prevent Readout GUI to begin a run. Whenever this happens (typically after clicking ''Begin'' in Readout GUI), the system sends an error message complaining about one of these processes still running.
