The figure below illustrates how the JAS supports intra-payload coincidence and triggering. There are two options:

Serial Packets

JAS nodes can transmit packetized signals via the communications architecture if latency requirements are not too stringent.

Discrete Signals

Discrete coincidence and trigger signals can be added to any node through the Expansion Profile. These signals can be dedicated copper or fiber. Discrete signals provide a low latency solution for coincidence signaling among nodes or sensors.
