Presentation Centering - Honeywell ORBIT 7120PLUS User Manual

Presentation Sensitivity is a numeric range that increases or decreases the scan-
ner's reaction time to bar code presentation. To set the sensitivity, scan the Sensi-
tivity bar code, then scan the degree of sensitivity (from 0-20) from the
Programming Chart,
ting, and 20 is the least sensitive. Default = 5.

Presentation Centering

Use Presentation Centering to narrow the imager's field of view to make sure the
scanner reads only those bar codes intended by the user. For instance, if multiple
codes are placed closely together, Presentation Centering will insure that only the
desired codes are read.
If a bar code is not touched by a predefined window, it will not be decoded or output
by the scanner. If Presentation Centering is turned on by scanning Presentation
Centering On, the imager only reads codes that pass through the centering win-
dow you specify using the Top of Presentation Centering Window, Bottom of
Presentation Centering Window, Left, and Right of Presentation Centering Win-
dow bar codes.
Example: In the example below, the white box is the centering window. The centering window
has been set to 20% left, 30% right, 8% top, and 25% bottom. Since Bar Code 1
passes through the centering window, it will be read. Bar Code 2 does not pass
through the centering window, so it will not be read.
