* The TDC start is provided by the [[Trigger|ULM trigger module]]. Since the delay of the S800 trigger may be adjusted during tuning of the S800 (XDT), the stop signals (e.g. from OBJ or XFP) need to be re-adjusted so that the ToF fits into the 400-ns range of the TDC. This is done manually for OBJ and XFP, and remotely via [[XLM Delay|XLM delay module]] (operated by the [[S800 DAQ tools#Delay Window|Delay GUI]]) for other timing signals | * The TDC start is provided by the [[Trigger|ULM trigger module]].
