-Events enter the ADC board and are stored in a pipeline buffer.
-The sum of the 16 channels are sent to the L1 Trigger board via optical fiber cables.
-L1 Trigger board sums a whole crate. This sum is passed via theP3 backplane to slot 12.
-MACTRIS sits in slot 12 and makes the decision to trigger (or not trigger) a data readout.
-L1A, 8ns clock, and LIVE signals are sent to the FANOUT crate’s Master FANOUT from MACTRIS.
-Master FANOUT sends signals out front panel ports to slave FANOUT boards.
-Each slave FANOUT board sends control signals, including L1A, which signals a trigger, to a whole crate of ADC boards.
-On a trigger, ADC boards will capture the data as it leaves the pipeline buffer and send it to the L2 Trigger board via optical fiber cables. (Note: the L2 Trigger Board has the same schematic design as the L1 Trigger Board, but has different firmware.)
-L2 Trigger board will buffer the data and package it for readout via Ethernet.
-An ethernet switch will connect 16 L2 Trigger boards to Mandolin
-Mandolin is a 40 node computer cluster. Each node will receive all channels of an event for processing and storage.
