Aimer Mode; Centering - Wasp 2D Reference Manual

Output

Aimer Mode

This feature allows you to lower peak current during scanning by alter-
nating 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
scanner 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 on page 3-11
tions 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.)
