Problem:


When the camera gets configured for triggering (i.e. hardware, free-running, and software), it will not respond to trigger requests immediately after being configured.


Solution:


It is recommended that you add a delay after configuring the camera for triggering before allowing/trying to acquire an image.


The delay we recommend depends on the camera in use:
