4.2.5
Acquisition Control Output Signals
The acquisition control block has the following output signals:
Acquisition Trigger Wait
An asserted acquisition trigger wait indicates, that the acquisition
control is waiting for an acquisition start trigger (see Section 4.2.3).
Acquisition Active
Acquisition active is a status signal, which is asserted, when the acquisition
has been started and deasserted, when the acquisition is stopped.
Acquisition Start
The acquisition start is an event, which is generated, when the acquisition is
started.
Acquisition End
The acquisition end is an event, which is generated, when the acquisition is
stopped.
Acquisition Trigger
The acquisition trigger is an event, which is generated, when the
acquisition is started by the acquisition start trigger (see Section 4.2.3).
Acquisition trigger wait and acquisition active status signal are routed to the I/O control block
and can there be selected for output on the physical output line or on one of the available leds
(see Chapter 6). Acquisition start, acquisition end and acquisition trigger event can be used to
trigger or to control other function in the camera, like counter or timer.

Figure 4.5: Frame Control Block
As soon as the acquisition is active the camera is ready to capture frames, which is controlled by
the frame control block. The behaviour depends on the frame start trigger, frame burst start
trigger and frame burst end trigger configuration.
4.3.1
Frame Start Trigger
The frame start trigger can be used to start a single frame capture. The main property of this
trigger is the trigger mode. It can be set to on or off:
Frame Start Trigger Mode = on
As soon as a frame start trigger has been received, a capture of
one frame will be started and the frame status goes to "Frame Active". Once one frame
has been processed, that camera status goes to "Frame Trigger Wait" again. The camera
is ready to process frame start triggers, when the acquisition is active, showed by the
"Acquisition Active" status, and when the "Frame Trigger Wait" status is asserted.
Frame Start Trigger Mode = off
The frame start triggers are ignored.
