This window will communicate statistics such as number of buffers read and number of events broadcast, and will also show error messages, should they occur. The EventBuilder window will appear as part of starting the [[s800 daq tools#run control window|Run Control]].

 +==== Mesytec CFD GUI ====
 +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 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).

 +  * To load the default CFD configuration go to **Load Setting**, select file **MCFD16.tcl** in directory **/user/operations/daq/usb/Config**, and click **Load**
 + 
 +  * Alternatively, it is possible to lead the configuration directly from the module by clicking **Update from Device**
 +
 +  * By default, the CFD parameters can be adjusted individually for each of the 16 channels. It is also possible use the module in a "common" mode to set the same CFD parameters to all channels. Just check **common**
 +
 +  * After modifying any of the CFD parameters, click **Commit to Device** 
 +
 +  * After adjusting the thresholds, the new configuration must be saved in file **MCFD16.tcl** in directory **/user/operations/daq/usb/Config**
 +
 +  * The MCFD module includes the possibility to send a periodic pulsing signal to all the channels. Two frequencies can be selected: 1.22 KHz, and 2.5 MHz

 This window appears when the "Init" button is pressed on the VME crate controller tab as part of the initial setup of the [[s800 daq tools#run control window|S800 USB daq]]. It can also be accessed by pressing the "Show GUIs" button. The delay module allows software configurable delays to be applied to each of the signals indicated in the Channel column, which then form the TDC stops. It is configurable to enable delays to be set with beam on target, as the needed delay may change depending on experimental conditions.  This window appears when the "Init" button is pressed on the VME crate controller tab as part of the initial setup of the [[s800 daq tools#run control window|S800 USB daq]].

-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 figure below shows the page "ratios" from the scaler GUI.+The GUI used to display scalers rates can be open from the icon **S800 Scalers** in the desktop of [[Software#u6pc5 (data U6)|u6pc5]]. Alternatively, open a terminal on u6pc5, and type **./goscalers** from directory **/user/s800/converged_daq/scalers**.
