Chapter 1 Introduction
Overview
TM
The NLS-EM3396 V2 OEM scan engine (hereinafter referred to as “the EM3396 V2”or “the engine”), armed with the
Newland patented , a computerized image recognition system, brings about a new era of 2D barcode scan engines.
The EM3396 V2’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 EM3396 V2 supports all mainstream 1D as well as PDF417, QR Code (QR1, QR2, Micro QR), Data Matrix and
GS1-DataBarTM(RSS) (Limited/ Stacked/ Expanded versions).
TM
Illumination
The EM3396 V2 has two red LEDs for supplementary lighting. The illumination can be programmed On or Off.
The EM3396 V2 uses red LEDs 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 turn off the engine’s illumination and use non-red
supplementary lighting (such as green) instead. The user can conduct some tests to determine the proper wavelengths to
be used.
Aimer
The EM3396 V2 contains a laser aimer that produces a crosshair aiming pattern to help the user to easily position the target
barcode within the engine’s field of view to increase scan efficiency. The aiming pattern can be turned On or Off. It is
advisable to turn it on when scanning barcodes.

Chapter 2 Installation
General Requirements
ESD
ESD protection has been taken into account when designing the EM3396 V2 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 EM3396 V2 must be sufficiently enclosed to prevent dust particles from gathering on the lens, circuit
boards and LEDs. Dust and other contaminants will eventually degrade the engine’s performance.

3
Ambient Environment
The following environmental requirements should be met to ensure good performance of the EM3396 V2:
Operating Temperature
-20℃to 55℃
Storage Temperature
-40℃to 70℃
Humidity
5% ~ 95% (non-condensing)
Thermal Considerations
Electronic components in the EM3396 V2 will generate heat during the course of their operation. Operating the EM3396 V2
continuously for an extended period may cause temperatures to rise on CIS and decoder chip. The following precautions
should be taken into consideration when integrating the EM3396 V2.
Reserve sufficient space for good air circulation in the design.
Avoid wrapping the EM3396 V2 with thermal insulation materials such as rubber.
Installation Orientation
There are two threaded mounting holes in the bottom of the EM3396 V2 for fastening the engine to a mounting surface with
machine screws. The following figure illustrates a front view of the EM3396 V2 after correct 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. 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=0.6mm) and the thickness of
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
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 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.
Scratch Resistance and Coating
Scratch on the window can greatly reduce the performance of the EM3396 V2. 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.
Horizontal:

6
Vertical:
Ambient Light
The EM3396 V2 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 EM3396 V2 uses red LEDs to create illumination beam. 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.
The EM3396 V2 uses a laser diode to form a bright, intuitive aiming aid. It is hazardous to stare into the laser beam.

7
Mounting (unit: mm)
The illustrations below show the mechanical mounting dimensions for the EM3396 V2. The structural design should leave
some space between components.

Chapter 3 Electrical Specifications
Power Supply
Do not power up the EM3396 V2 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. The minimum interval must exceed 2
seconds.
Ripple Noise
Image sensor and decoder chip are directly fed by the input power of EM3396 V2. To ensure the image quality, a power
supply with low ripple noise is needed.
Acceptable ripple range (peak-to-peak) : ≤50mV (≤30mV recommended).

1. In the diagram above, it takes A+B+C (about 400ms) for the engine to power up: Ais bootloader execution time
(100ms), Bis kernel boot time (50ms) and Cis decoding chip initialization time(250ms). Waken-up duration from the
deep low consumption mode is 300ms.
2. D is reset time. If the Reset signal is not operated when powered on, the startup time should be calculated after VDD
reaches 3.3V.
3. Ensure that all communication interface data has been transmitted before powering off.
4. Levels of other signals should be kept low before power-on to prevent abnormal function.
5. The nTrig signal comes with 100K pull-up. During the period from the power-on to bootloader execution, do not pull
down the nTrig signal. If nTrig is set high and then power the engine on, it should also meet the E
duration (E=0~1ms).
