Chapter 1 Getting Started
Introduction
The EM3080 V2 is an area image engine for barcode reading.
LED Compliance Statement
The EM3080 V2 complies with IEC 62471:2006 for LED safety.
The EM3080 V2 contains:
•a CMOS image sensor and its lens
•1 LED for illumination and aiming
Figure 1-1 System Block Diagram
The 12-pin FFC connector on the engine can be connected to a host device with an FFC cable. For information about this
cable, please see the “12-pin FFC Cable” section in Chapter 4.
Illumination & Aimer
The EM3080 V2 uses one red LED for supplementary lighting and to produce a square-shaped aiming pattern to help the

4
user to position the target barcode within the engine’s field of view. The illumination can be programmed On or Off.
The EM3080 V2 uses the red LED 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 use non-red supplementary lighting (such as green).
The user can conduct some tests to determine the proper wavelengths to be used.

Chapter 2 Installation
Introduction
This chapter explains how to install the EM3080 V2, including general requirements, housing design, and physical and
optical information.
△
！Caution: Do not touch the imaging lens when installing the engine. Be careful not to leave fingerprints on the lens.
△
！Caution: Do not touch the illumination LED during handling. Improper handling may damage the LED.
General Requirements
ESD
ESD protection has been taken into account when designing the EM3080 V2. However, due to limited board space,
additional ESD protection, such as TVS protection, is not provided on the engine’s I/O interface. It is advised to take
corresponding protection measures when integrating the engine.
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 EM3080 V2 must be sufficiently enclosed to prevent dust particles from gathering on the lens and circuit board. 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 EM3080 V2.

Storage Temperature
-40℃to 70℃
Humidity

Thermal Considerations
Electronic components in the EM3080 V2 will generate heat during the course of their operation. Operating the EM3080 V2
in continuous mode for an extended period may cause temperatures to rise on CPU, CIS, LEDs, DC/DC, etc. Overheating
can degrade image quality and affect scanning performance. Given that, the following precautions should be taken into
consideration when integrating the EM3080 V2.
Avoid continuous use of the LED for prolonged periods.
Reserve sufficient space for good air circulation in the design.
Avoid wrapping the EM3080 V2 with thermal insulation materials such as rubber.
External Optical Elements
Do not subject external optical components on the engine to any external force. Do not hold the engine by an external
optical component, which may cause the mechanical joints that secure the components to crack or break due to excessive
stress.
Installation Orientation
The Figure 2-1 illustrates a front view of the EM3080 V2 after correct installation.
Figure 2-1
Mounting (Unit: mm)
The illustrations below show the mechanical mounting dimensions for the EM3080 V2. The structural design should leave
some space between components and reserve sufficient room for the installation of the FFC cable.

Housing Design
※Note: Conduct an optical analysis for the housing design to ensure optimal scanning and imaging performance.
Housing design should make sure that internal reflections from the aiming and illumination system are not directed back to
the engine. The reflections from the housing or window can cause problems. For particular window tilt angles, the
unwanted reflections can bounce off the top or bottom and reach the engine. Avoid any highly reflective objects around the
engine that can cause bright spots to appear in the captured image. It is recommended to use baffles or matte-finished dark
internal housing colors.
Optics
The EM3080 V2 uses a sophisticated optical system. An improperly designed internal housing or improper selection of
window material can degrade the engine’s performance.
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 of the engine).
There are two window placement options.
•Parallel window –Primary option for imager engines. The following window distance requirements should be satisfied:
The maximum distance is measured from the front of the engine housing to the furthest surface of the window. In order to
reach better reading performance, the distance from the front of the engine housing to the nearest surface of the window
should not exceed a(a=1mm) and the distance from the front of the engine housing to the furthest surface of the window
should not exceed a+d (a=1mm, d=2mm), as shown in Figure 2-5.
•Tilted window –This is not recommended. For the tilted window distance requirements, please see Table 2-2.

Window Material and Color
Window material must be clear. Use only cell-cast plastics or optical glass. PMMA,ADC and chemically tempered glass are
recommended. Window material selected for the engine should meet or exceed the specifications specified in Table 2-3.
•PMMA (Cell-cast acrylic): When fabricated by cell-casting, has very good optical quality and low initial cost, but surface
must be protected from the environment due to its susceptibility to attack by chemcials, mechanical stresses, and UV
light. Reasonably good impact resistance. This material can be laser-cut into odd shapes and ultrasonically welded.
•ADC (CR-39): A thermal-setting plastic produced by the cell-casting process. Excellent chemical and environmental
resistance. Quite good surface hardness, and therefore does not have to be hard-coated. Reasonably good impact
resistance. This material cannot be ultrasonically welded.
•Chemically tempered glass: Glass is a hard material which provides excellent scratch and abrasion resistance. But
unannealed glass is brittle. Increased flexibility strength with minimal optical distortion requires chemical tempering.
Glass is hard to be cut into odd shapes and cannot be ultrasonically welded.

Pay extra attention to the wavefront distortion when using plastic materials. Plastic materials are not recommended for
tilted windows; colored windows are not recommended if the engine is used to scan barcodes on moving objects.
Coatings and Scratch Resistance
Scratch on the window can greatly reduce the performance of the EM3080 V2. It is suggested to use abrasion resistant
window material or coating.
The following introduces two commonly-used types of coatings:
•Anti-reflection coatings: Anti-reflection (AR) coatings can be applied to window surfaces to reduce reflected light from
the window back into the engine. But they are expensive and have poor abrasion/scratch resistance.
•Polysiloxane coatings: Polysiloxane coatings can be applied to plastic surfaces to increase the surfaces’ abrasion and
scratch resistance.
Both tempered glass and plastic windows can be AR coated. However, it is easier and more cost-effective to put an AR
coating on the glass than on the plastic.
The AR coating specifications below should be met when using anAR coated window.
Single side AR coating: 92% minimum transmittance within spectrum range from 420 nm to 730 nm.
Double side AR coating: 97% minimum transmittance within spectrum range from 420 nm to 730 nm.

11
Window Size
The window must not block the field of view and should be sized to accommodate the aiming and illumination envelopes
shown below.

Roll, Skew and Pitch
Three different reading angles, roll, skew and pitch are illustrated in Figure 2-8. Roll refers to rotation around the Z axis,
skew to rotation around the X axis and pitch to rotation around the Y axis. For the engine’s technical specifications, please
visit the Newland website or contact your dealer.
Figure 2-8
Ambient Light
The EM3080 V2 shows better performance with ambient light. However, high-frequency pulsed light can result in
performance degradation.
Eye Safety
The EM3080 V2 has no lasers. It uses one LED to produce illumination and aiming beams. The LED is 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.

Chapter 3 Electrical Specifications
Power Supply
Do not power up the EM3080 V2 until it is properly connected. Be sure the power is cut off before connecting a cable to or
disconnecting a cable from the host interface connector. Hot-plugging could damage the engine.
Unstable power supply or sharp voltage drops or unreasonably short interval between power-ons may lead to unstable
performance of the engine. Do not resupply the power immediately after cutting it off.
Ripple Noise
To ensure the image quality, a power supply with low ripple noise is needed.
Acceptable ripple range (peak-to-peak): ≤30mV

Timing Sequence
Power Up and Power Down Timing Sequence
Figure 3-1
1. In the diagram above, it takes A+B (about 3200ms) for the engine to power up: Ais reset time (about 200ms), Bis time
needed to start the engine. The engine is ready to receive commands via its serial/USB port after the power-up
sequence completes.
2. Cis the time it takes to power down the engine (during power-down, all voltages in the engine ramp down, with all
communication stopped and all signals at a low level). To ensure that all voltages are fully down and signals on the
interfaces at a low level, the minimum interval between removing and resupplying the power must exceed 700ms.
