Chapter 1 Introduction
Overview
TM
The EM3296 OEM scan engines, armed with the Newland patented , a computerized image
recognition system, bring about a new era of 2D barcode scan engines.
The EM3296
’s 2D barcode decoder chip ingeniously blends
technology and advanced chip design
& manufacturing, which significantly simplifies application design and delivers superior performance and
solid reliability with low power consumption.
The EM3296 supports all mainstream 1D as well as PDF417, QR Code (QR1, QR2, Micro QR), Data
Matrix, GS1-DataBar
TM
(RSS) (Limited/ Stacked/ Expanded versions) and Chinese Sensible Code.
Illumination
The EM3296 has two red LEDs for supplementary lighting, making it possible to scan barcodes even in
complete darkness. The illumination can be programmed On or Off.
The EM3296 uses red LEDs for illumination, so 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 (such as green) instead. The user can
conduct some tests to determine the proper wavelengths to be used.
Aimer
The EM3296 has a view finder that produces a solid round-shaped 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.
