 The main purpose of the trigger is to implement a coincidence between the S800 focal-plane fast timing scintillator [[Detectors#Plastic scintillators|E1]] and a secondary detector principally located at the target location. This coincidence is often a mandatory requirement when the trigger rate of the S800 alone (S800 singles) is too high for the data acquisition and the resulting dead time is prohibitive.  The main purpose of the trigger is to implement a coincidence between the S800 focal-plane fast timing scintillator [[Detectors#Plastic scintillators|E1]] and a secondary detector principally located at the target location.

 The S800 trigger logic is built in a LeCroy ULM2367 FPGA module. Note that this module could be replaced in the future by another FPGA module provided it has enough NIM or ECL input/outputs (such as the VME XLM72 module for instance). This section describes the functionality of the S800 trigger module and the commands used to control its parameters.  The S800 trigger logic is built in a LeCroy ULM2367 FPGA module.
