NLS-EM2028二维影像式条码识读引擎 ，采用先进的图像传感技术和国际领先水平的新大陆UIMG ®智能图像识别系统。 Product introduction NLS-EM2028 two-dimensional image-type barcode reading engine , using advanced image sensing technology and the international advanced level of the New World UIMG ® intelligent image recognition system. Advanced image sensing technology avoids image distortion due to jitter or motion. The organic integration with New World UIMG ® technology enables the reading engine to easily read barcodes on various media such as paper and plastic with strong performance.
NLS-EM2028 can read all kinds of mainstream standard two-dimensional bar codes (PDF417, QR Code, Data Matrix, etc.) and China's two-dimensional bar code standards-Han Xin code. Not only support mainstream one-dimensional barcodes (UPC, EAN ,, Code 39, Code 128, Code 93, Code 11, Interleaved 2 of 5, Industrial 2 of 5, Matrix 2 of 5, MSI / Plessey, Plessey), but also read The latest GS1-DataBarTM (RSS) bar codes, including Limited, Stacked, Expanded and other versions.
NLS-EM2028 has a compact design size and weight, and provides a wealth of communication interfaces. There are HID-KBW, virtual serial port, DataPipe and other methods based on USB interface; the serial communication interface is also available in TTL232 and RS232 versions, which is very suitable for embedding in products of various industries, such as cash register, data collector, meter reading Equipment, ticket machines, PDAs, etc.
To cope with the possible complexity of various applications, NLS-EM2028 uses a powerful CPU and provides a secondary development function SDK that develops the underlying API interface. It can also quickly develop and cope with complex applications.
