AW00011916000 Image Acquisition Control
Basler scout GigE 131
9.6.1.2 Acquisition Start Trigger Mode = On
When the Trigger Mode parameter for the acquisition start trigger is set to on, you must apply an
acquisition start trigger signal to the camera each time you want to begin a frame acquisition. The
Trigger Source parameter specifies the source signal that will act as the acquisition start trigger
signal. The available selections for the Trigger Source parameter are:
 Software - When the source signal is set to software, you apply an acquisition start trigger
signal to the camera by executing a Trigger Software command for the acquisition start trigger
on the host PC.
 Line 1 or 2 - When the source signal is set e.g. to line 1, you apply an acquisition start trigger
signal to the camera by injecting an externally generated electrical signal (commonly referred
to as a hardware trigger signal) into physical input line 1 on the camera.
If the Trigger Source parameter is set to Line 1 or Line 2, you must also set the Trigger Activation
parameter. The available settings for the Trigger Activation parameter are:
 Rising Edge - specifies that a rising edge of the electrical signal will act as the acquisition start
trigger.
 Falling Edge - specifies that a falling edge of the electrical signal will act as the acquisition start
trigger.
For more information about using a software trigger to control frame acquisition start, see
Section 9.4.4 on page 115.
For more information about using a hardware trigger to control frame acquisition start, see
Section 9.4.5 on page 116.
Exposure Time Control with the Acquisition Start Trigger Mode On
When the Trigger Mode parameter for the acquisition start trigger is set to on and the Trigger Source
parameter is set to software, the exposure time for each frame acquisition is determined by the
camera’s exposure time parameters.
When the Trigger Mode parameter is set to on and the Trigger Source parameter is set to e.g. input
line 1, the exposure time for each frame acquisition can be controlled with the exposure time
parameters or it can be controlled by manipulating the hardware trigger signal.
For more information about controlling exposure time when using a software trigger, see
Section 9.4.4 on page 115.
For more information about controlling exposure time when using a hardware trigger, see
Section 9.4.5 on page 116.
For more information about exposure time parameters, see Section 9.7 on page 141.
By default, input line 1 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 9.2 on page 105 and Section 9.4 on
page 111.
