Preparing the Vision System
The vision system learns the fiducial during a board setup. The fiducial
coordinates are entered into the product file during the editing of a default file.
This enables the camera to find the fiducials initially. The setup needs to be run
in step mode from the status page.
The following procedure is typical for all fiducial shapes, although in this
instance a circle fiducial shape is referred to throughout.
Video Model
The procedure for Creating a Video Model is very similar to that for a
fiducial, throughout this following Fiducial procedure, boxes like this
contain alternative procedure steps, to allow the setup of a Video Model.

The board fiducial/select mark should now be visible on the vision data window.
If selective print/pass through is enabled, the image on the left hand side of the
monitor is the board select mark. The right hand side of the monitor shows the
corresponding position on the screen, which is a mirror image of the board
without the select mark. While the select mark is being setup and the menu bar is
as Step 8, the message ‘The form of this fiducial will select Print / Pass
through.’ is displayed.
If the fiducial is in the field of view go to Step 10. If the fiducial is not in the field
of view, continue with Step 8.
