Centering

Use Centering to narrow the imager’s field of view to make sure the imager reads only those bar

codes intended by the user. For instance, if multiple codes are placed closely together, centering

will insure that only the desired codes are read.

In the example below, the gray area is the full imager field of view and the white area is the

centering window. Bar Code 1 will not be read, while Bar Code 2 will be.

The default centering window is a 60 pixel square area in the center of the imager’s field of view.

The following diagram illustrates the default top, bottom, left, and right pixel positions, measured

from the top and the left side of the imager’s field of view, which is 640 by 480 pixels.

40% 60% 100%

The centering window must intersect the center of the image. If a bar code is not within the

predefined window, it will not be decoded or output by the imager. If centering is turned on by

scanning Centering On, the imager only reads codes that intersect the centering window you

specify using the Top, Bottom, Left, or Right bar codes.

Scan Centering On, then scan one of the following bar codes to change the top, bottom, left, or

right of the centering window. Then scan the percent you want to shift the centering window using

digits in Appendix D of this manual. Scan Save. Default Centering = 40% for Top and Left, 60% for

Bottom and Right.
