About This Guide
Introduction
TM
The NLS-EM50S-10/NLS-EM50S-20 OEM scan engines (hereinafter referred to as “the EM50S ” 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, magnetic card, mobile phones
and LCD displays. The EM50S can be easily integrated into OEM equipment or systems, such as handheld, portable, or
stationary barcode scanners. The EM50S offers fully open image acquisition interface, raw data interface and I/O interface,
which enable 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.

Aimer
The 12-pin FPC connector on the engine can be connected to a host device with an FFC cable. For information about this
cable, please see the “12-pin FFC Cable” section in Chapter 4.
Illumination
The EM50S has a white LED for supplementary lighting, making it possible to scan barcodes even in complete darkness.
The illumination can be turned On or Off. Besides, external illumination LED for further improving lighting can be turned On
by programming PIN 8 of the 12-pin FPC connector on the engine when needed.
Aimer
The EM50S 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.
