Auto Trigger Overview
To capture a barcode, the scanner
uses ambient light to detect differences
in contrast between the light and dark
areas of a barcode.
If the scanner is in auto trigger mode
and it detects differences in movement,
it begins scanning. Different time
values can be specified to control how
sensitive the scanning operation is to
movement.
