   * There are four "Delay Inspect" channels (routed to the patch panel in data U6) which can be selected using the Delay GUI
   * These "Delay Inspect" signals can be compared with any one of the four "Trigger Inspect" channels in order to set proper delays for the TDCs. The "Trigger Inspect" channels can be selected using the [[S800 DAQ tools#Trigger GUI|ULM trigger GUI]]
+  * TDCs of last 4 listed signals (including XF and object scintillators) are bypassed with cable delays and thus their delays cannot be controlled with the GUI. They can be inspected, however using the GUI
+  * The TDC delays can only be changed when the run control is stopped; must SAVE settings before starting run control not to overwrite adjustments being made
+  * The “S800” trigger used as reference to calculate the ToF is from E1 up signal
+  * The signal delays controlled by the GUI (and not by cable delays) are not “pipelined” -- i.e., any new signals that arrive during the delay time of a previous signal are lost and thus deadtime is introduced into the system.  The signals delayed passively by cables are “pipelined” and thus are not subject to deadtime losses
