7.4.2 Acquisition Frame Count (Standard Mode)
When the Trigger Mode parameter for the acquisition start trigger is set to on, you must set the value
of the camera’s Acquisition Frame Count parameter. The value of the Acquisition Frame Count can
range from 1 to 255.
With acquisition start triggering on, the camera will initially be in a "waiting for acquisition start
trigger" acquisition status. When in this acquisition status, the camera cannot react to frame start
trigger signals. If an acquisition start trigger signal is applied to the camera, the camera will exit the
"waiting for acquisition start trigger" acquisition status and will enter the "waiting for frame start
trigger" acquisition status. It can then react to frame start trigger signals. When the camera has
received a number of frame start trigger signals equal to the current Acquisition Frame Count
parameter setting, it will return to the "waiting for acquisition start trigger" acquisition status. At that
point, you must apply a new acquisition start trigger signal to exit the camera from the "waiting for
acquisition start trigger" acquisition status.
7.4.3 Setting the Acquisition Start Trigger Mode and
Related Parameters (Standard Mode)
You can set the Trigger Mode and Trigger Source parameters for the acquisition start trigger and
also set the Acquisition Frame Count parameter value from within your application software by
using the Basler pylon API.
The following code snippet illustrates using the API to set the Trigger Mode to on, the Trigger
Source to software, and the Acquisition Frame Count to 5:
// Set the acquisition mode to continuous(the acquisition mode must
// be set to continuous when acquisition start triggering is on)
When the Trigger Mode parameter for the acquisition start trigger is set to
on, the camera’s Acquisition Mode parameter must be set to continuous.
By default, input line 2 is selected as the source signal for the acquisition start
trigger.
Keep in mind that the camera will only react to acquisition start triggers when it is
in a "waiting for acquisition start trigger" acquisition status. For more information
about the acquisition status, see Section 7.2 on page 79 and Section 7.4 on
page 85.
