About This Guide
Introduction
TM
The NLS-EM20-M37 OEM scan engines (hereinafter referred to as “the EM20-M37” 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 EM20-M37 can be easily integrated into OEM equipment or systems, such as handheld, portable, or
stationary barcode scanners. The EM20-M37 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.
