acquisition start trigger" acquisition status and will remain in that status until a new acquisition start
trigger signal is applied.
As an example, assume that the Acquisition Frame Count parameter is set to three and that the
camera is in a "waiting for acquisition start trigger" acquisition status. When an acquisition start
trigger signal is applied to the camera, it will exit the "waiting for acquisition start trigger" acquisition
status and enter the "waiting for frame start trigger" acquisition status. Once the camera has
received three frame start trigger signals, 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 the camera
to make it exit "waiting for acquisition start trigger".
Frame Start Trigger
Assuming that an acquisition start trigger signal has just been applied to the camera, the camera
will exit from the "waiting for acquisition start trigger" acquisition status and enter a "waiting for
frame start trigger" acquisition status. Applying a frame start trigger signal to the camera at this point
will exit the camera from the "waiting for frame start trigger" acquisition status and will begin the
process of exposing and reading out a frame (see Figure 20 on page 67). 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 that are applied to the camera when it is not in a "waiting for frame start trigger"
acquisition status will be ignored.
