Image Acquisition Control
Acquisition Burst Frame Count parameter setting. The camera will then return to the "waiting for
frame burst start trigger" acquisition status. In order to acquire more frames, you must apply a new
frame burst start trigger signal to the camera to exit it from the "waiting for frame burst start trigger"
acquisition status.
When the Trigger Mode parameter for the frame burst start trigger is set to on, you must select a
source signal to serve as the frame burst start trigger. The Trigger Source parameter specifies the
source signal. The available selections for the Trigger Source parameter are:
Software – When the source signal is set to software, you apply a frame burst start trigger

signal to the camera by executing an Trigger Software command for the frame burst start
trigger on the host PC.
Software 1, Software 2, Software 3 – Specific software commands, analogous to the Software

command.
Line 1 – When the source signal is set to Line 1, you apply a frame burst 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 Line 1 on the camera.
Line 3 – Analogous to the Line 1 source signal. However, the GPIO line Line 3 must be

configured for input.
Line 4 – Analogous to the Line 3 source signal.

If the Trigger Source parameter for the frame burst start trigger is set to Line 1, Line 3 or Line 4 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 frame burst start

trigger.
Falling Edge - specifies that a falling edge of the electrical signal will act as the frame burst

start trigger.
When the Trigger Mode parameter for the frame burst start trigger is set to
on, the camera's Acquisition Mode parameter must be set to continuous.
