Introduction
The EM3080-W is an area image engine for bar code reading. It includes an LED
illumination system.
The EM3080-W includes:
- 1 CMOS imaging sensor
- 1 LED based on the illumination system
Block Diagram
The engine connected with the host via the 12-pin FPC cable. For more details about the 12-pin FPC cable, please see 12-pin FPC in Chapter 4.
Illumination
The EM3080-W has 1 white LED for supplementary lighting, making it possible to
scan barcodes even in complete darkness. The illumination can be turned On or
Off.
Installation
Introduction
This chapter mainly describes how to install the engine and provides physical
and electrical information, cautions and window properties.
Caution Do not touch the imaging lens during the installation. Do not leave the fingerprints on the lens.
General Requirements
ESD
ESD protection has been taken into account when designing the EM3080-W 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 EM3080-W 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-W.
Table 2-1
Operating Temperature | -20℃ to 50℃ |
---|---|
Storage Temperature | -40℃ to 70℃ |
Humidity | 5% ~95% (non-condensing) |
Thermal Considerations
Electronic components in the EM3080-W will generate heat during the course of
their operation. Operating the EM3080-W 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-W.
- Avoid running the engine continuously with LEDs on for long time.
- Reserve sufficient space for good air circulation in the design.
- Avoid wrapping the EM3080-W with thermal insulation materials such as rubber.
External optical elements
Do not subject external optical elements on the engine to any external force
and avoid holding the engine by an external optical element, which will result
in excessive stress and cause failure.
Installation Orientation
The Figure 2-1 illustrates a front view of the EM3080-W after correct
installation.
Mounting
The illustrations below show the mechanical mounting dimensions for the
EM3080-W. The structural design should leave some space between components.
Front View (unit: mm)
Bottom View (unit: mm)
Side View (unit: mm)
Housing Design
Note : Conduct optical analysis for the housing design to obtain optimal scanning and imaging operation. Housing design intends to prevent reflections from the aiming and illumination system. Especially reflections from the tilted window can bounce off from the top or the bottom and finally reach the engine. Keep away from the bright objects that can be reflected. Consider baffles or matte-finished dark colors.
Optics
The EM3080-W uses a sophisticated optical system. An improper enclosure
window material will have an influence on the performance of the engine.
Window Placement
Properly place the window in order to prevent reflection back into the engine.
If the enclosure can’t meet the recommended window angle, contact Newland to
discuss positioning matters. Improper position will dramatically affect the
performance. here are two alternatives to position the window. Parallel – The
window should be positioned properly to let the illumination beam pass through
as much as possible and no reflections back into the engine. 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 be less than 1mm. For the window
distance, please see Figure 2-5.
Tilted – This is for laser or imager engines. For the window distance, please see Table 2-2.
Note: Use the parallel or tilted window to read the barcodes. The dust and scratches on the tilted window will result in bad performance in the imaging system.
The window should be positioned properly to let the illumination 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.The vertical
distance between the farthest surface of the window and the engine front
surface should not exceed a + d, and that between the nearest surface of the
window and the engine front surface should not exceed a mm (a=1mm, d=2mm).

Window Material and Color
Many window materials include stresses and distortions, which leads to poor
performance. So use only cell-cast plastics or optical glass. There are three
common window materials, chemically tempered glass, PMMA and ADC. Below are
the recommended window features.

Consider the wavefront distortion when using plastic materials Plastic materials are not recommended if the window is designed as tilted, because scratches will reduce the performance. If the motion detection mode is needed, colored windows are not recommended as well Wavelength of the illumination and aiming 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 of red light over 90% and haze less than 1%. Whether to use an anti-reflection coating or not depends on the material and application needs.
PMMA
PMMA is made by casting acrylic between two sheets of glass. It obtains the
advtanges of high quality, good impact resistance and low cost, while it is
soft and brittle. Polysiloxane coating is recommended to avoid attack from
stresses. Acrylic is enabled to be cut into kinds of shapes and welded
ultrasonically.
ADC
ADC obtain good chemical and environmental resistance and impact resistance.
Because of its hardness, coating is not required except some terrible
circumstances. Ultrasonical welding is not allowed..
Chemical Tempering Glass
Glass offers optimal scratch and abrasion resistance. But, unannealed glass is
easily broken. Chemical tempering can greatly enhance its flexibility. Glass
is hard to be cut into different shapes and can’t be ultrasonically welded.
Coatings
Anti-reflection coatings
Anti-reflection coatings are applied for stray light control. The window with
anti-reflection coatings can minimize influence caused by the reflection. But
they have high cost and terrible abrasion and scratch resistance.
Polysiloxane Coating
Polysiloxane coatings are used to prevent plastic surfaces from scratch and
abrasion. The specifications below are available if anti-reflective coating is
applied. Polysiloxane coating is not needed.
Specifications | Description |
---|
Material
| Exit windows made of tempered glass or plastic can be AR coated. The AR coated glass
features better adhesion. What’s more, putting AR coating on the glass is more cost-effective.
Anti-reflection Coating
| Single side: the minimum transmittance is 92% within spectrum range from 420 nm to 730 nm. Double side: the minimum transmittance is 97% within spectrum range from 420 nm to 730 nm.
For more details about parallel windows, please see Figure 2-6.
Scratch Resistance and Coating
Scratch on the window can greatly reduce the performance of the EM3080-W. 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. Optical areas for illumination
Optical Area of Lens
Ambient Light
The EM3080-W shows better performance with ambient light. However, high-
frequency pulsed light can result in performance degradation.
Eye Safety
The EM3080-W 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.
Electrical Specifications
Power Supply
Do not power up the EM3080-W until it is properly connected. Be sure the power
is cut off before connecting a flexible cable to or disconnecting a flexible
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. It is advised that the
minimum interval should exceed 500ms. The EM3080-W itself does not provide a
power switch. Users can switch the engine off by cutting off the power.
Switching it on and off frequently will not shorten the service life of the
EM3080-W. The EM3080-W’s start-up time is less than 200ms.
Ripple Noise
Image sensor and decoder chip are directly fed by the input power of EM3080-W.
To ensure the image quality, a power supply with low ripple noise is needed.
Acceptable ripple range (peak-to-peak) : ≤50mV (≤30mV recommended).

Dimensions of the Connector
The EM3080-W uses a 12-pin FPC connector.
12-pin FPC Connector
The EM3080-W uses a 12-pin ZIF connector (bottom contact). This connector can
be connected to a host device with an FFC cable. Parameters are shown as
below.
FFC Cable (unit: mm)
A 12-pin FFC cable (contacts on the same side or on opposite sides) can be
used to connect the EM3080-W to a host device. The cable design must be
consistent with the specifications shown below. Use reinforcement material for
the connectors on the cable and reduce cable impedance for reliable connection
and stable performance.
Timing Sequence
Power Up and Power Down Timing Sequence
- A represents reset time, about 200ms.
- B represents time for starting the engine. The total is A plus B, about 3200ms. The engine can receive serial commands or USB communication immediately when it is powered on.
- C is the power-down time, indicating all the voltages’ drop time in the module, that is, the communication is stopped and the level is low. In order to ensure the voltage is fully down and the level of each interface is low, at least 700ms interval is required to start the engine again.
