Random Dot Beads
When this bead type is enabled, the normal bead duration is broken into
dots. The size of each dot is programmed in 0.1 ma increments with a
maximum value of 50.0 ms. The spacing between the dots (pitch) is
programmed in millimeters from 2 - 9999 mm.
The pattern controller automatically determines the length of each product
as it passes the trigger and then sizes the beads to fit the product.
