Chapter 1 Introduction
Overview
TM
NLS-EM3070 series OEM scan engines (hereinafter referred to as “the EM3070”or “the engine”), armed
with the Newland patented , a computerized image recognition system, bring about a new era of 2D
barcode scan engines.
The EM3070’s 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 EM3070 supports all mainstream 1D and standard 2D barcode symbologies (e.g., PDF417, QR
Code M1/M2/Micro and Data Matrix) as well as GS1-DataBarTM(RSS) (Limited/Stacked/Expanded
versions).
Aimer
The EM3070 has a view finder that projects an aiming beam to help the user to position the target
barcode within the engine’s field of view to increase scan efficiency. The aimer can be programmed On or
Off. It is advisable to turn it on when scanning barcodes.
Illumination
The EM3070 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 use of red light as illumination and the engine’s lens imaging system designed to work better with red
light result in that 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 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 EM3070 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 EM3070 must be sufficiently enclosed to prevent dust particles from gathering on the imager and
lens. Dust and other external contaminants will eventually degrade the engine’s performance.
Ambient Environment
The following environmental requirements should be met to ensure good performance of the EM3070:
Working Temperature
-20℃to 55℃
Storage Temperature
-40℃to 80℃
Humidity
5% to 95% (non-condensing)
Thermal Considerations
Electronic components in the EM3070 generate heat during the course of their operation. Operating the
EM3070 in continuous mode for an extended period may result in an increase in temperature by 20℃
inside the engine. The following precautions should be taken when integrating the EM3070:
Reserve sufficient space for good air circulation during design.
Avoid wrapping the EM3070 with thermal insulation materials such as rubber.

Installation Orientation
The following figure illustrates a front view of the EM3070 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 farthest 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
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 EM3070. 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.
