9.4 The Acquisition Start Trigger in
Standard Mode
For more information about standard mode and legacy mode and how to set them, see Section 9.1
on
page 103 .
The acquisition start trigger is used in conjunction with the frame start trigger to control the
acquisition of frames. In essence, the acquisition start trigger is used as an enabler for the frame
start trigger. Acquisition start trigger signals can be generated within the camera or may be applied
externally as software or hardware acquisition start trigger signals.
When the acquisition start trigger is enabled, the camera’s initial acquisition status is "waiting for
acquisition start trigger". When the camera is in this acquisition status, it will ignore any frame start
trigger signals it receives. If an acquisition start trigger signal is applied to the camera, it will exit the
"waiting for acquisition start trigger" acquisition status and enter the "waiting for frame start trigger"
acquisition status. In this acquisition status, the camera can react to frame start trigger signals and
will begin to expose a frame each time a proper frame start trigger signal is applied.
A primary feature of the acquisition start trigger is that after an acquisition start trigger signal has
been applied to the camera and the camera has entered the "waiting for frame start trigger"
acquisition status, the camera will return to the "waiting for acquisition start trigger" acquisition
status once a specified number of frame start triggers has been received. Before more frames can
be acquired, a new acquisition start trigger signal must be applied to the camera to exit it from
"waiting for acquisition start trigger" status. Note that this feature only applies when the Trigger
Mode parameter for the acquisition start trigger is set to on. This feature is explained in greater
detail in the following sections.
This section only applies if the standard mode is enabled for image acquisition
control.
When the camera is started for the first time after delivery from the factory the
image acquisition control will not be in standard mode but in legacy mode.
Use the legacy mode only if you want to operate the camera together with
previous cameras not featuring the standard mode.
