Page 7: Chapter 1 Introduction
Chapter 1 Introduction Product Overview NLS-EM2039 series embedded 2D barcode scan engines, armed with the Newland patented computerized image recognition system, bring about a new era of 2D barcode scan engines. The EM2039s’ decoder chip ingeniously blends technology and advanced chip design &... -
Page 8: Illumination
Illumination The EM2039 has two red LEDs (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. Since red light is used as illumination and the engine’s lens imaging system is coated with AR film which has obvious anti-reflection effect against red light, the engine shows better reading performance on barcodes printed in non-red colors. -
Page 9: Chapter 2 Installation
Chapter 2 Installation General Requirements ESD protection has been taken into account when designing the EM2039 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 EM2039 must be sufficiently enclosed to prevent dust particles from gathering on the imager and lens. -

Page 11: Optics
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. -
Page 12: Window Material And Color
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%. - Page 13 Illumination & Aiming Fig. 2-3 Fig. 2-4...

Page 14: Ambient Light
Fig. 2-5 Fig. 2-6 Ambient Light The EM2039 shows better performance with ambient light. However, high-frequency pulsed light can result in performance degradation. Eye Safety The EM2039 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. -
Page 15: Mounting
Mounting The EM2039s provide combined type (imager and decoder board assembled on an L-shaped bracket) and discrete type (imager and decoder board separated) to cater for different mounting needs. For the combined type, the user can simply mount the EM2039 on the target device. The combined type is easy for integration and is suitable for devices with enough space inside. - Page 16 Bottom View Fig. 2-8 Top View Fig. 2-9...
