Presentation Centering - Honeywell Xenon 1900 User Manual

Presentation Centering

Use Presentation Centering to narrow the scanner's field of view when it is in the
stand 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.
Note: To adjust centering when the scanner is hand-held, see
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 scanner 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.
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.
Note: A bar code needs only to be touched by the centering window in order to be read. ?It
does not need to pass completely through the centering window.
