Exposure Start Trigger
Applying an exposure start trigger signal to the camera will exit the camera from the waiting for
exposure start trigger acquisition status and will begin the process of exposing and reading out
a frame (see
). As soon as the camera is ready to accept another exposure start
trigger signal, it will return to the waiting for exposure start trigger acquisition status. A new
exposure start trigger signal can then be applied to the camera to begin another frame exposure.
The exposure start trigger has two modes: off and on.
If the
Trigger Mode
parameter is set to
Off
, the camera will generate all required exposure start
trigger signals internally, and you do not need to apply exposure 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 is set to
On
, you must trigger exposure start by applying exposure
start trigger signals to the camera. Each time a trigger signal is applied, the camera will begin
a frame exposure. When exposure 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.).
Exposure start trigger signals applied to the camera when it is not in a waiting for exposure
start trigger acquisition status will be ignored.
