Chapter 1 Introduction

Overview

The NLS-EM3396 OEM scan engine (hereinafter referred to as “the EM3396”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’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 supports all mainstream 1D as well as PDF417, QR Code (QR1, QR2, Micro QR), Chinese

Sensible Code, Data Matrix and GS1-DataBarTM(RSS) (Limited/ Stacked/ Expanded versions). TM

Illumination

The EM3396 has two red LEDs for supplementary lighting. The illumination can be programmed On or

Off.

The EM3396 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 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 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.

Note: The EM3396’s laser diode (circled in the figure below) is ESD sensitive and rated Class 1A Human

Body Model (HBM) 270V, thus ESD protection measures, such as the ones mentioned above, must be

taken when handling or installing the EM3396 to avoid damage to the laser diode.

Dust and Dirt

The EM3396 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.

Ambient Environment

The following environmental requirements should be met to ensure good performance of the EM3396:

Operating Temperature

-20℃to 55℃

Storage Temperature

-40℃to 70℃

Humidity

5% ~ 95% (non-condensing)

Thermal Considerations

Electronic components in the EM3396 will generate heat during the course of their operation. Operating

the EM3396 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.

Reserve sufficient space for good air circulation in the design.

Avoid wrapping the EM3396 with thermal insulation materials such as rubber.

Installation Orientation

There are two threaded mounting holes in the bottom of the EM3396 for fastening the engine to a

mounting surface with machine screws. The following figure illustrates a front view of the EM3396 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.
