Decoded (Internal) 2D Scanning Options
Linear security level
3
specifies that code types other than the following must be success-
fully 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
When this parameter is enabled, a bar code must be successfully scanned in both directions
(forward and reverse) before being decoded.
Scan Angle
This option allows you to choose from two scan angles:
Normal Angle
or
Alternate Angle
.
Choosing
Normal Angle
allows the normal operation for scanning long range and short
range. Choosing
Alternate Angle
widens the beam to allow scanning of long bar codes at
short range but at the cost of long range scanning.

Decoded (Internal) 2D Scanning Options
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 parameters determine the laser pattern’s height and rate of expansion.
Code Type
Length
MSI Plessey
4 or less
D 2 of 5
8 or less
I 2 of 5
8 or less
Note: This parameter is only valid if a “Linear Security Level” is enabled.
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.
