Overview
NLS-EM3070 series OEM scan engines (hereinafter referred to as "the EM3070" or "the engine"), armed
with the Newland patented
barcode scan engines.
The EM3070's decoder chip ingeniously blends
manufacturing, which significantly simplifies application design and delivers superior performance and
solid reliability with low power consumption.
The EM3070 supports all mainstream 1D and standard 2D barcode symbologies (e.g., PDF417, QR
Code M1/M2/Micro and Data Matrix) as well as GS1-DataBarTM(RSS) (Limited/Stacked/Expanded
versions).
Aimer
The EM3070 has a view finder that projects an aiming beam to help the user to position the target
barcode within the engine's field of view to increase scan efficiency. The aimer can be programmed On or
Off. It is advisable to turn it on when scanning barcodes.
Illumination
The EM3070 has several red LEDs (wavelength: 625±10nm) for supplementary lighting, making it
possible to scan barcodes even in complete darkness. The illumination can be programmed On or Off.
The use of red light as illumination and the engine's lens imaging system designed to work better with red
light result in that the engine shows better reading performance on barcodes printed in non-red colors.
For applications involving red barcodes, it is advised to turn off the engine's illumination and use
non-red supplementary lighting instead. The user can conduct some tests to determine the proper
wavelengths to be used.
