Aimer Mode
This feature allows you to turn the aimer on and off. When the Interlaced bar-
code is scanned, the aimer is interlaced with the illumination LEDs.
Centering
Use Centering to narrow the image scanner’s field of view to make sure the
image scanner reads only those barcodes intended by the user. For instance, if
multiple codes are placed closely together, centering will insure that only the
desired codes are read. (Centering can be used in conjunction with Aimer
Delay, page 4-10, for the most error-free operation in applications where multi-
ple codes are spaced closely together. Using the Aimer Delay and Centering
features, the image scanner can emulate the operation of older systems, such
as linear laser barcode image scanners.)
In the example below, the gray area is the full image scanner field of view and
the white area is the centering window. Barcode 1 will not be read, while Bar-
code 2 will
be.
The default centering window is a 128x96 pixel area in the center of the image
