Scanning Options
The scanner has 3 scanning options: aiming dot, slab raster and
always raster.
Aiming Dot
A trigger pull creates the single aiming dot pattern, which lasts for a
fixed interval. This dot is easily visible in outdoor or high ambient
light environments. After the aiming dot, a slab raster or open raster
pattern appears, depending on the configured scanning option. You
can select the aiming dot option with either a normal or extended
timeout period.
Slab Raster
A trigger pull creates the slab raster pattern. If the target is a 1-D bar
code, the pattern never opens beyond a slab raster. If the target is a
2-D (PDF417) bar code, the pattern opens to an optimized raster
pattern when the scanner is properly aligned over the bar code.
Always Raster
A trigger pull opens to a full raster pattern.
