DS2100N REFERENCE MANUAL

4.1.1 Important ACB Reading Conditions

• Do not use ACB for omni-directional reading stations.

• ACB can be activated for each symbology independently from the others.

• ACB requires that the code be in movement with respect to the scanner.

• ACB requires fixed length barcode reading.

• The codes read with ACB enabled must pass in front of the scanner one at a time.

Not valid for ACB

Valid for ACB

• Code concatenation and ACB are not compatible and therefore cannot be enabled

simultaneously on the same code.

• For correct operation, ACB requires at least 5 scans for each of the two fragments.

4.1.2 Tilt Angle Improvement with ACB

ACB allows barcode reading with an increased tilt angle. The tilt angle depends upon the

code aspect ratio defined as H/L according to the table below:

4.2 LINEAR CODE READING

The number of scans performed on the code by the DS2100N and therefore the decoding

capability is influenced by the following parameters:

• number of scans per second

• code motion speed

• label dimensions

• scan direction with respect to code motion

At least 5 scans during the code passage should be allowed to ensure a successful read.
