IMAGETEAM™ 2020/4620 System Manual

Aimer Mode
This feature allows you to lower peak current during scanning by alternating the
aimer and illumination LEDs. When the
Interlaced
bar code is scanned, the
aimer and illumination LEDs are not allowed to be on at the same time. While
this does limit peak current during scanning, the imager performance may be
slower. When the
Concurrent
bar code is scanned, the aimer and illumination
LEDs are allowed to light at the same time. Select
Off
if you don’t want to use
either aimer mode.
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. (Centering can be used in conjunction with
Aimer Delay
, page 4-10, for
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 bar code imagers.)
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.
