Chapter 1 Introduction
Overview
TM
The EM3090 OEM scan engine, armed with the Newland patented , a computerized image
recognition system, brings about a new era of 2D barcode scan engines.
The EM3090’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 EM3090 supports all mainstream 1D as well as PDF417, QR Code (QR1, QR2, Micro QR), Chinese
Sensible Code, Data Matrix and GS1-DataBarTM(RSS) (Limited/ Stacked/ Expanded versions).
Aimer
The EM3090 has a view finder that produces a bar-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.
Illumination
The EM3090 has several red LEDs (wavelength: 625±10nm) for supplementary lighting, making it
possible to scan barcodes even in complete darkness. The illumination can be programmed On or Off.
The EM3090 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.

Chapter 2 Installation
General Requirements
ESD
ESD protection has been taken into account when designing the EM3090 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.
Dust and Dirt
The EM3090 must be sufficiently enclosed to prevent dust particles from gathering on the lens, circuit
boards and LEDs. Dust and other contaminants will eventually degrade the engine’s performance.
Ambient Environment
The following environmental requirements should be met to ensure good performance of the EM3090:
Operating Temperature
-20℃to 55℃
Storage Temperature
-40℃to 80℃
Humidity
5% ~ 95% (non-condensing)
Thermal Considerations
Electronic components in the EM3090 will generate heat during the course of their operation. Operating
the EM3090 continuously 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 EM3090.
Reserve sufficient space for good air circulation during design.
Avoid wrapping the EM3090 with thermal insulation materials such as rubber.

Installation Orientation
The following figure illustrates a front view of the EM3090 after 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 furthest surface of the window. Avoid unwanted
reflections and use thin material for window so as to reach better reading performance. As shown in the
figure below, 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 above distance requirements should be met and tilt
angle should ensure no reflections back into the lens.

Window Material and Color
Wavelengths of illumination and aiming beams should be taken into consideration when choosing window
material and color, 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
of illumination and aiming beams over 90% and haze less than 1%. Whether to use an anti-reflection
coating or not depends on the material and application needs.
Scratch Resistance and Coating
Scratch on the window can greatly reduce the performance of the EM3090. 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 aiming and
illumination envelopes shown below.
