-Probably the most appealing feature of this module is the possibility to remotely control the trigger timing and configuration while beam is present in the vault, since most experiments are nowadays locating their electronics close to the detectors.

For more details on this detector check section [[Trigger#Trigger module|Trigger module]].
-The S800 trigger from the [[Detectors#Plastic scintillators|E1 scintillator]] provides also the reference time for the [[Detectors#Cathode Readout Drift Chambers (CRDC)|CRDCs]] as well as time-of-flight measurements. Note that because the FPGA uses a 40 MHz internal clock, the time reference of the signals in the trigger circuit are set the phase of that clock, and therefore jitter by 25 ns with respect to the source signals. This jitter is measured with a TDC and can be subtracted to the time measurements to recover the timing relative to the source signals.
