Figure 35. ACR Readable Codes

ACR is disabled by default but can be enabled for the following code types:

•

Code 25 Interleaved

•

Code 39 Family

•

Codabar

•

GS1 DataBar

•

Code 128/EAN128

•

EAN/UPC (without Add-Ons)

•

Code 93

•

GS1 DataBar Expanded

9.1.1 Important Advanced Code Reconstruction Reading Conditions

•

Do not use Advanced Code Reconstruction (ACR) for omni-directional reading stations

•

Code concatenation and ACR are not compatible and therefore cannot be enabled simultaneously

•

Stacked codes and ACR are not compatible

•

Codes shorter than 4 digits, while readable linearly, cannot be reconstructed in ACR

NOTE: To maximize scanner performance in Advanced Code Reconstruction Reading applications:

•

Enable only the code symbologies used in the application and disable any code symbologies not

used in the application

•

Reconstruct only one code label at a time

•

Use conveyor speeds less than or equal to 1.0 m/s

9.1.2 Tilt Angle for Advanced Code Reconstruction

The most important parameter in Advanced Code Reconstruction is the value of the maximum tilt angle (

maximum)

under which the code reconstruction process is still possible.

Laser Beam

= tilt angle

0° to

max
