Acquisition Status Indicator; Trigger Ready Signal - Basler SCOUT LIGHT User Manual

Image Acquisition Control
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about changing the assignment of camera output signals to the physical
output line, see Section 8.2.1 on
For more information about the electrical characteristics of the camera's output line, see
Section 7.7.2 on page

9.10.2 Acquisition Status Indicator

When controlling image acquisition with a software trigger you can use the acquisition status feature
to determine when the camera is rady to be triggered for an image acquisition.
For more information about the acquisition status feature, see Section 11.11 on

9.10.3 Trigger Ready Signal

As described in the previous section, the cameras can operate in an "overlapped" acquisition
fashion. When the camera is operated in this manner, it is especially important that:
the exposure time of a new image acquisition not start until exposure of the previously
acquired image is complete, and
the exposure time of a new image acquisition not end until readout of the previously acquired
image is complete.
The camera supplies a "Trigger Ready" (TrigRdy) output signal you can use to ensure that these
conditions are met when you are using a hardware trigger signal to trigger image acquisition. The
trigger ready signal relates to different trigger signals, depending on the image acquisition control
mode:
In standard mode, the trigger ready signal relates to the frame start trigger signal
In legacy mode, the trigger ready signal relates to the acquisition start trigger signal.
When you are acquiring images, the camera automatically calculates the earliest moment that it is
safe to trigger each new acquisition. The trigger ready signal will go high when it is safe to trigger
an acquisition, will go low when the acquisition has started, and will go high again when it is safe to
trigger the next acquisition (see Figure 43). The camera calculates the rise of the trigger ready
signal based on the current exposure time parameter setting, the current size of the area of interest,
and the time it will take to readout the captured pixel values from the sensor.
The trigger ready signal is especially useful if you want to run the camera at the maximum
acquisition frame capture rate for the current conditions. If you monitor the trigger ready signal and
you trigger acquisition of each new image immediately after the signal goes high, you will be sure
that the camera is operating at the maximum acquisition frame rate for the current conditions.
