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.

4
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.

5
Ambient Light
The EM3070 shows better performance with ambient light. However, high-frequency pulsed light can
result in performance degradation.
Eye Safety
The EM3070 has LEDs that create the aiming and illumination beams. These 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.
Mounting
The illustrations below show the mechanical mounting dimensions for the EM3070. The structural design
should leave some space between components and provide sufficient space for flat flexible cable.
Elements listed in previous sections should also be taken into consideration when integrating the
EM3070.

Chapter 3 Electrical Specifications
Power Supply
Do not power up the EM3070 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. This 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. The
minimum interval must exceed 2 seconds.
Ripple Noise
To ensure the image quality, a power supply with low ripple noise is needed.
Acceptable ripple range (peak-to-peak) : ≤50mV (≤30mV recommended).

Host Interface Connector
The EM3070’s host interface connector is a 12-pin ZIF socket which can be used to connect a host
device (e.g., software development board EVK) with a flat flexible cable. The following figures show the
location and dimensions of the socket. (unit: mm)

11
Dimensions of the Host Interface Connector

12
Flat Flexible Cable
A 12-pin flat flexible cable can be used to connect the EM3070 to a host device. The cable design must
be consistent with the following specifications shown below. Use reinforcement material for the
connectors on the cable and reduce cable impedance for reliable connection and stable performance.
Cable Connection
Be sure the power is cut off before connecting a flexible cable to the host interface connector on the
EM3070. Hot plugging could damage the engine or the host device.
Connect the EM3070 to a host device with a 12-pin flexible cable as shown in the following figure.

13
Communication Interfaces
The EM3070 can communicate with the host device through either TTL-232 serial port or USB port using
one of the following communication modes.
TTL-232: This interface is applicable to most system architectures. For those requiring RS-232, a
TTL-232 to RS-232 conversion circuit is needed.
USB HID-KBW: Based on USB connection, the engine’s transmission is simulated as USB keyboard
input. It works on a Plug and Play basis and no driver is required.
USB COM Port Emulation: The USB port on the host device is emulated as a serial port with the
same data transmission and configuration as a real serial port. A driver is required.
USB HID-POS: It is based on HID with no need for custom driver and is way more efficient in
communication than keyboard emulation and traditional RS-232 interface.
The EM3070’s serial port supports baud rates from 1200bps to 115200bps; it does not support hardware
flow control.
Control Interfaces
Reset
Driving the RESET pin (PIN 11) on the host interface connector low for 100μs-500μs and then having the
signal back to high or idle high level resets the EM3070.
The minimum interval between reset operations must exceed 2 seconds.
Trigger
Driving the TRIG pin (PIN 12) on the host interface connector low for a specified time period causes the
EM3070 to start a scan and decode session. The time period varies from one scan mode to another.
Anti-shake mechanism is used in level trigger mode. For this mode, a trigger begins when the signal from
the TRIG pin remains low for at least 10ms.
For those scan modes with a timeout mechanism, the trigger automatically deactivates when the timeout
expires. After a trigger ends, the engine gets ready for next trigger only if the signal from the TRIG pin
remains high for at least 10ms.

14
Beeper
The EM3070 provides a pin (BUZ, PIN 9) on the host interface connector that provides a PWM output to
an external driver circuit for generating audible feedback to the user to indicate statuses like power up,
good read or operation error. The PWM output is not strong enough to drive a beeper, so a beeper driver
circuit is needed.
The following beeper driver circuit is provided for reference.
