Chapter 1 Introduction
Overview
TM
Illumination
Aimer
The LV3296 OEM scan engines, armed with the Rakinda patented , a computerized image
recognition system, bring about a new era of 2D barcode scan engines.
The LV3296’s 2D barcode decoder chip ingeniously blends technology and advanced chip design
& manufacturing, which significantly simplifies application design and delivers superior performance and
solid reliability with low power consumption.
The LV3296 supports all mainstream 1D as well as PDF417, QR Code (QR1, QR2, Micro QR), Data
Matrix and GS1-DataBarTM(RSS) (Limited/ Stacked/ Expanded versions).
The LV3296 has two red LEDs for supplementary lighting, making it possible to scan barcodes even in
complete darkness. The illumination can be programmed On or Off.
The LV3296 uses red LEDs for illumination, so the engine shows better reading performance on
barcodes printed in non-red colors. For applications involving red barcodes, it is advised to turn off the
engine’s illumination and use non-red supplementary lighting (such as green) instead. The user can
conduct some tests to determine the proper wavelengths to be used.
The LV3296 has a view finder that produces a solid circle-shaped aiming pattern to help the user to
easily position the target barcode within the engine’s field of view to increase scan efficiency. The aiming
pattern can be turned On or Off. It is advisable to turn it on when scanning barcodes.

General Requirements
ESD
Dust and Dirt
Ambient Environment
Operating Temperature -20℃~ 50℃
Storage Temperature -40℃~ 80℃
Humidity 5% ~ 95% (non-condensing)
Thermal Considerations
ESD protection has been taken into account when designing the LV3296 and the engine is shipped in
ESD safe packaging. Always exercise care when handling the engine outside its package. Be sure
grounding wrist straps and properly grounded work areas are used.
The LV3296 must be sufficiently enclosed to prevent dust particles from gathering on the imager, lens
and circuit board. Dust and other external contaminants will eventually degrade the engine’s
performance.
The following environmental requirements should be met to ensure good performance of the LV3296:
Electronic components in the LV3296 will generate heat during the course of their operation. Operating
the LV3296 in continuous mode for an extended period may cause temperatures to rise on CIS and
decoder chip. Overheating can degrade image quality and affect scanning performance. Given that, the
following precautions should be taken into consideration when integrating the LV3296.
Reserve sufficient space for good air circulation in the design.
Avoid wrapping the LV3296 with thermal insulation materials such as rubber.

Installation Orientation
The LV3296 has two threaded mounting holes for machine screws on its bottom. The following figure
illustrates a front view of the LV3296 after correct installation.

Optics
Window Placement
The window should be positioned properly to let the illumination and aiming beams pass through as much
as possible and no reflections back into the engine (reflections can degrade the reading performance).
The window should be mounted close to the front of the engine (parallel). The maximum distance is
measured from the front of the engine housing to the farthest surface of the window. In order to reach
better reading performance, the distance from the front of the engine housing to the furthest surface of the
window should not exceed 3mm and the distance from the front of the engine housing to the nearest
surface of the window should not exceed 2mm.
If the window is required to be in a tilted position, the distance requirements above should be met and tilt
angle should ensure no reflections back into the lens.
Window Material and Color
CIS’s responsiveness (mainly to wavelengths of red light）should be taken into consideration when
choosing window material and color, in order to achieve the possible highest spectral transmission, lowest
haze level and homogeneous refractive index. It is suggested to use PMMA or optical glass with spectral
transmittance over 90% and haze less than 1%. Whether to use an anti-reflection coating or not depends
on the material and application needs.

≤3mm

Scratch Resistance and Coating
Scratch on the window can greatly reduce engine performance. It is suggested to use abrasion resistant
window material or coating.
Window Size
The window must not block the field of view and should be sized to accommodate the illumination
envelope shown below.

Eye Safety
The LV3296 shows better performance with ambient light and it is well able to handle the flicker in
fluorescent lights using 50-60Hz AC power. However, high-frequency pulsed light can result in
performance degradation.
The LV3296 has no lasers. It uses LEDs to produce illumination and aiming beams. The LEDs are bright,
but testing has been done to demonstrate that the engine is safe for its intended application under
normal usage conditions. However, the user should avoid looking into the beam.
