Chapter 5: Configuration
Decoded (Internal) Scanners
“Linear security level 3” specifies that code types other than the following must be
successfully read twice before being decoded. The following codes must be read
three times:
“Linear security level 4” requires that all code types be successfully read three times
before being decoded.
Bi-Direction Redundancy
Note: This parameter is only valid if a” Linear Security Level” is enabled.
When this parameter is enabled, a bar code must be successfully scanned in both
directions (forward and reverse) before being decoded.
5.11.3.3 Decoded (Internal) 2D Scanning Options (SE2223 only)
Scanning Mode
When you double-tap on this parameter, a dialog box is displayed in which you can
choose one of the following scanning modes: Smart Raster, Always Raster,
Programmable Raster, Slab Pattern, Cyclone Pattern or Semi-Omni Pattern.
Raster Height And Raster Expand Rate
These parameter determine the laser pattern’s height and rate of expansion.
Note: These parameters are only used when either Programmable Raster or
Always Raster is assigned to the “2D Scanning Mode” parameter.
“2D Raster Height” and “2D Raster Expand Rate” are intended
for very specific applications and are usually not required for normal
scanning purposes.
Double-tapping on this parameter displays a dialog box in which you can enter a
value from
1 to 15.
