Abstract
A system and method includes a master/slave data bus, a plurality of sensing nodes, and a master node configured to communicate with the plurality of sensing nodes over the master/slave data bus. The master node is configured to command the plurality of sensing nodes into an event monitoring mode over the master/slave data bus. The plurality of sensing nodes are configured to digitize and retain a first amount of data during a listening mode of the event monitoring mode and detect an event based upon the first amount of data. The plurality of sensing nodes are further configured to drive an event trigger on the master/slave data bus upon detection of the event, and digitize and retain a second amount of data following detection of the event trigger on the master/slave data bus.
