Basler scout GigE 107
process of exposing and reading out a frame (see Figure 46 on page 107 ). As soon as the camera
is ready to accept another frame start trigger signal, it will return to the "waiting for frame start
trigger" acquisition status. A new frame start trigger signal can then be applied to the camera to
begin another frame exposure.
The frame start trigger has two modes: off and on.
If the Trigger Mode parameter for the frame start trigger is set to off, the camera will generate all
required frame start trigger signals internally, and you do not need to apply frame start trigger
signals to the camera. The rate at which the camera will generate the signals and acquire frames
will be determined by the way that you set several frame rate related parameters.
If the Trigger Mode parameter for the frame start trigger is set to on, you must trigger frame start by
applying frame start trigger signals to the camera. Each time a trigger signal is applied, the camera
will begin a frame exposure. When frame start is being triggered in this manner, it is important that
you do not attempt to trigger frames at a rate that is greater than the maximum allowed. (There is
a detailed explanation about the maximum allowed frame rate at the end of this chapter.) Frame
start trigger signals applied to the camera when it is not in a "waiting for frame start trigger"
acquisition status will be ignored.
= a frame start trigger signal that will be ignored because the camera
is not in a "waiting for frame start trigger" status
= camera is waiting for an acquisition start trigger signal
= camera is waiting for a frame start trigger signal
= frame exposure and readout
Acquisition Frame Count parameter setting = 3
