DS2400N REFERENCE MANUAL

3.3 POSITIONING

The DS2400N scanner is able to decode moving barcode labels at a variety of angles,

however significant angular distortion may degrade reading performance.

When mounting the DS2400N take into consideration these three ideal label position angles:

Skew 10° to 30°, Tilt 0° and Pitch 0°.

Follow the suggestions for the best orientation:

The Skew angle is represented by the value

S in Figure 35. Position the reader to assure

at least 10° for the Skew angle. This avoids

the direct reflection of the laser light emitted

by the DS2400N.

For the raster version, this angle refers to the

most inclined or external raster line, so that all

other raster lines assure more than 10°

Skew.

The Tilt angle is represented by the value T

in Figure 36. Position the reader in order to

minimize the Tilt angle.

By using the Reconstruction Reading Mode

software parameter, the tilt angle is less

critical and can be decoded even if the scan

line doesn’t cross the entire code.

See par. 7.1 or the Help On Line for details.

The Pitch angle is represented by the value

P in Figure 37. Position the reader in order

to minimize the Pitch angle.
