About This Guide
Introduction
TM
The NLS-EM20-85 OEM scan engines (hereinafter referred to as “the EM20-85” or “the engine”) are armed with CMOS
image capturer and the Newland patented , a computerized image recognition system-on-chip, featuring fast
scanning and accurate decoding on barcodes on virtually any medium-paper. The EM20-85 can be easily integrated into
OEM equipment or systems, such as handheld, portable, or stationary barcode scanners. The EM20-85 offers fully open
image acquisition interface, raw data interface and I/O interface, which enables users to easily develop their own
applications with Newland’s SDK.
※Note: This guide provides general instructions for the installation of the engine into a customer's device. Fujian
Newland Auto-ID Tech. Co., Ltd. recommends an opto-mechanical engineer should conduct an opto-mechanical analysis
before integration.

Chapter 1 Getting Started
Introduction
The EM20-85 is an area image engine for barcode reading. It includes four illumination LEDs and a 12-pin FPC connector
and a 8-pin box connector.
LED Compliance Statement
The EM20-85 complies with IEC 62471:2006 for LED safety.
The EM20-85 contains:
•a CMOS image sensor and its lens
•four LEDs
•a 12-pin FPC connector
•a 8-pin box connector
Figure 1-1 System Block Diagram
The 12-pin FPC connector/8-pin box connector on the engine can be connected to a host device with an appropriate cable.
For more information about this connector, please see Chapter 3.
4
Illumination
The EM20-85 has four white LEDs for supplementary lighting, making it possible to scan barcodes even in complete
darkness. The illumination can be programmed On or Off.
Buzzer
The EM20-85 provides a buzzer to indicate power-on and good read statuses. The Power On Beep and Good Read Beep
can be programmed On or Off, and the Good Read Beep Volume, Duration and Frequency are also programmable by the
user. To learn how to program these parameters, please see the EM20-85 user guide.

Chapter 2 Installation
Introduction
This chapter explains how to install the EM20-85, including general requirements, housing design, and physical and optical
information.
△
！Caution: Do not touch the imaging lens when installing the engine. Be careful not to leave fingerprints on the lens.
General Requirements
ESD
ESD protection has been taken into account when designing the EM20-85. However, due to limited board space, additional
ESD protection, such as TVS protection, is not provided on the engine’s I/O interface. It is advised to take corresponding
protection measures when integrating the engine.
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 EM20-85 must be sufficiently enclosed to prevent dust particles from gathering on the lens and circuit board. 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 EM20-85.
Table 2-1
Operating Temperature
-20°C ~ 60°C
Storage Temperature
-40°C ~ 75°C
Humidity
5% ~95% (non-condensing)
