Description
type of trigger is used when synchronization
with another device is part of the image
acquisition setup or when speed is required.
A hardware device can process an input
signal much faster than software. For more
information, see “Using a Hardware Trigger”
on page 6-14.
Note: Only a subset of image acquisition
devices supports hardware triggers. To
determine the trigger types supported
by your device, see “Determining Valid
Configurations” on page 6-6.
Using an Immediate Trigger
To use an immediate trigger, simply create a video input object. Immediate triggering
is the default trigger type for all video input objects. With an immediate trigger, the
object executes the trigger immediately after you start the object running with the start
command. The following figure illustrates an immediate trigger.
