| 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). | 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/s800daq** 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" may 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 Trigger GUI appears when the "Launch ULM GUI" button is pressed on [[#Readout GUI]]. The Trigger GUI is a visual display of the various Gate and Delay Generators and logic elements that make up the configurable trigger of the S800. The logic of the trigger decision is readily discerned from a visual inspection of this GUI.

| The different signal going through the trigger scheme can be inspected in th Data-U6 oscilloscope. Simply right click on any of the wires to put that signal onto one of the four "Trigger Inspect" channels available at the patch panel of Data-U6, and connect that patch-panel cable to the oscilloscope. By inspecting the various delays, widths and overlaps the user trigger can be configured.

| | The Trigger (ULM) GUI allows the user to select the S800 timestamp clock: either the internally generated clock from the ULM, or an external clock from an ancillary system (e.g. GRETINA). In the latter case, you have to make sure to check the two boxes on the bottom of the Trigger GUI labeled "External timestamp clock" and "external sync select". |

| The GUI used to display scalers rates can be open from the icon **S800 Scalers** in the desktop of [[Software#u6pc5 (data U6)|u6pc5]].

| The GUI includes two pages labeled "s800" and "ratios". Page "s800" includes all the scaler channels; page "ratios" displays ratio values calculated between several pairs of channels. In addition, the GUI includes a panel showing the time evolution of the live time calculated from the live-to-raw trigger ratio, and the live-to-raw clock ratio.

| 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/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. | The S800 DAQ can be run in Standalone mode (as described above), or in Slave mode.
