 Because the USB-based S800 data acquisition uses independent crate controllers that perform the readout in parallel, time stamping and busy schemes are incorporated in the trigger to synchronize events and insure no trigger is generated while readout sequences are being executed. Because of this modularity, adding an external data acquisition system (typically from an external detector), is straightforward.  Because the USB-based S800 data acquisition uses independent crate controllers that perform the readout in parallel, time stamping and busy schemes are incorporated in the trigger to synchronize events and insure no trigger is generated while readout sequences are being executed.

The schematics of the firmware is available.  The Verilog code of the REGISTERS module of the FPGA configuration, responsible for the communication with the VME bus is also available. +The time stamp module is implemented in a VME XLM72 (SpartanXL) FPGA.
