Acquisition can be aborted on any X, Y, Z, or V boundary. The choice of boundary
depends on whether one wants to abort immediate, which can cause acquisition of
incomplete frames, or one wants to stop at the end of the line/frame/volume, which
provides a more graceful end to acquisition.
It’s easiest to think of the Acquisition Engine level in terms of a state machine. When a
window is “opened” the run level moves down to the next state below. When a win-
dow “closes”, the run level moves to the state above. If the window at the top level
closes, the run level goes to idle. Figure 2-2 illustrates this type of state machine:

The action that causes a window to be opened or closed depends on the type of win-
dow. Some windows can be opened in more than one way. For example the Y win-
dow can be opened when a Start Of Frame (SOF) packet is sent from the camera, or it
can be opened by a trigger (all SOF packets are ignored until the trigger condition is
