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

-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 "Launch Gate Delay GUI" button is pressed on the [[#Readout GUI|Readout GUI]].
