4600g, 4600r, 4800i User’s Guide 3 - 11
Aimer Mode
Note: Concurrent is the default for units with 4X00 engines. Interlaced is the
default for units with 5X00 engines. Refer to the Show Engine
Revision on page 11-1 for information on determining the engine in your
unit. The 4600r does 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 bar code 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 bar code 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 applications 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 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 3-10, 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.)
