Chapter 1 Introduction
Overview
TM
NLS-EM3080 series embedded 2D barcode scan engines, armed with the Newland patented , a
computerized image recognition system, bring about a new era of 2D barcode scan engines.
The EM3080’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 EM3080 supports all mainstream 1D as well as PDF417, QR Code (QR1、QR2、Micro QR), Data
Matrix and GS1-DataBarTM(RSS) (RSS-Limited, RSS-14, RSS-14 Stacked and RSS-Expand).
Illumination
The EM3080 has a red LED (wavelength: 625±10 nm) 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 results 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.
Aimer
The EM3080 uses the red LED and projection lens to produce two brighter aiming beams over the
borders of illumination envelope to indicate the engine’s field of view.

Chapter 2 Installation
General Requirements
ESD
ESD protection has been taken into account when designing the EM3080 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 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 EM3080:
Working Temperature
-20℃to 60℃
Storage Temperature
-40℃to 85℃
Humidity
5% to 95% (non-condensing)
Thermal Considerations
Electronic components in the EM3080 will generate heat during the course of their operation. Operating
the EM3080 in continuous mode for an extended period may cause temperatures to rise on CIS and
decoder chips. Overheating can degrade image quality and affect scanning performance. Given that, the
following precautions should be taken into consideration when integrating the EM3080.
Reserve sufficient space for good air circulation in the design.
Avoid wrapping the EM3080 with thermal insulation materials such as rubber.

Installation Orientation
The following figure illustrates a front view of the EM3080 after installation, with the engine’s decoder
board on the top, and illumination and lens on the front.
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. 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 not exceed 2mm.

4
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
Illumination wavelengths and CIS’s responsiveness (mainly to wavelengths of red 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 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 engine performance. It is suggested to use abrasion resistant
window material or coating.

5
Window Size
The window must not block the field of view and should be sized to accommodate the aiming and
illumination envelopes shown below.

6
Ambient Light
The EM3080 shows better performance with ambient light and it is well able to handle the flicker in
fluorescent lights using 50-60Hz AC power. However, high-frequency pulsed light can result in
performance degradation.
Eye Safety
The EM3080 has an LED what creates the aiming and illumination 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.

7
Mounting
The illustrations below show the mechanical mounting dimensions for the EM3080. The structural design
should leave some space between components.

Chapter 3 Electrical Specifications
Power Supply
Do not power up the EM3080 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 500ms.
The EM3080 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.
The EM3080’s start-up time is less than 200ms.
Ripple Noise
Image sensor and decoder chip are directly fed by the input power of EM3080. 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 Host Interface Connector
The EM3080’s host interface connector is a 12-pin ZIF socket which can be used to connect a host
device with a flat flexible cable. The following figure shows the dimensions of the socket. (unit: mm)
Flat Flexible Cable
A 12-pin flat flexible cable can be used to connect the EM3080 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.

13
Communication Interface
EM3080 (TTL-232 version):
The EM3080 can communicate with the host device through TTL-232 serial port. This interface is
applicable to most system architectures. For those requiring RS-232, a TTL-232 to RS-232 conversion
circuit is needed.
Baud rates supported: 1200bps, 2400bps, 4800bps, 9600bps, 14400bps, 19200bps, 38400bps,
57600bps and 115200 bps.
Default settings: 9600 bps, 8 data bits, no parity check, 1 stop bit.
The TTL-232 interface does not support hardware flow control or software flow control.
EM3080-01 (USB version):
The EM3080-01 can communicate with the host device through one of the following interfaces:
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 DataPipe：This protocol is defined by Newland. A driver is required when using this protocol to
communicate with scanner.
HID-POS: HID-POS does not require a custom driver. However, an HID interface on Windows 98
does. All HID interfaces employ standard driver provided by the operating system.

14
Trigger
Driving the nTrig pin (PIN 12) on the host interface connector low causes the EM3080 to start a scan and
decode session. If barcode is decoded, the EM3080 waits for the voltage at the nTrig pin to turn high (or
the trigger to be released) after sending the data to the Host. If the trigger is released during a scan
attempt, the EM3080 stops decoding.
Next decode session does not happen until the EM3080 receives active trigger signal (driving the nTrig
pin low) again.
As a decode session involves image capture, barcode decoding and other steps, it is suggested that the
minimum interval between two triggers should exceed 50ms.
