 ==== Time Stamping Scheme ====
-Because the USB-based S800 data acquisition uses independent crate controllers that perform the readout in parallel, time stamping schemes are incorporated in the trigger to synchronize events. Because of this modularity, adding an external data acquisition system (typically from an external detector), is straightforward. More details about the time stamping module can be found in section "[[Trigger#Time stamping|Time stamping]]".

Because of this modularity, the same synchronization scheme can be used when coupling external data acquisition systems to the S800.

 ===== Trigger module =====
-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.
