Application Notes
1. If a Rapid Capture trigger mode is enabled, the timing on the trigger will change
when Synchronous Trigger mode is enabled, and will probably not be sufficient for
most applications. This is because the trigger can have up to a 16ms delta from the
time the trigger is issued until the image capture occurs. Thus the trigger timing will
not be stable and should not be used in a dynamic applications.
2. If the IP database is being used in a Continuous Capture mode, the capture
sequence is sequential and no longer double buffered. Thus a capture cannot occur
until the previous frame has been processed and up to a 16ms delay can be introduced
between image captures.
3. In a Continuous trigger, Continuous Capture, or read rate mode, the decode
speed should not be affected (while using the synchronous trigger mode) since a
double buffer format is used for image capturing. The only time a slow down should
be noticed in these modes is when the decode time is less than the capture time.
Capture time = 16ms.
