Aimer Mode
Note: Concurrent is the default for units with 4X00 engines. Interlaced is the
default for units with 5X00 engines. Refer to the
on page 11-1 for information on determining the engine in your
unit. The 4600g, 4600r, 4800i, and 4600rp do not allow concurrent aimer
mode.
The Aimer Mode feature allows you to lower peak current during scanning by
alternating the aimer and illumination LEDs. When the Interlaced barcode is
scanned, the aimer and illumination LEDs are not allowed to be on at the same
time. Interlaced, the recommended setting for the 5X00 engines, limits the
peak current draw during scanning. For 4X00 engines, the Interlaced setting
reduces the frame capture rate. When the Concurrent barcode is scanned, the
aimer and illumination LEDs are allowed to light at the same time. This is the
recommended setting for the 4X00 engines. Select Off for fixed mount applica-
tions when the aimer is not needed.
Centering
Use Centering to narrow the imager’s field of view to make sure the imager
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
the most error-free operation in applications where multiple codes are spaced
closely together. Using the Aimer Delay and Centering features, the imager can
emulate the operation of older systems, such as linear laser barcode imagers.)
In the example below, the gray area is the full imager field of view and the white
area is the centering window. Barcode 1 will not be read, while Barcode 2 will
be.
