duty cycle, even when the imager exposure time is at its maximum in
dark operating environments.
Concurrent mode provides the brightest appearance of the illumination
LEDs of any of the imager operating modes. This mode may be useful
for applications when an operator is using the illumination LEDs for
aiming, such as in fixed mount, kiosk, or auto trigger applications.
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 3-12 , for the most error-free operation in applica-
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.)
