Chapter One About NLS-EM20-EX
NNLS-EM20-EX Two-dimensional image-based embedded application barcode reading engine, using the world's leading chip-based New World
The new era of 2D barcode reading engine.
Intelligent image recognition technology, creating image style
Newland’s two-dimensional decoding chip will be advanced
The difficulty of product design has set an excellent benchmark for high performance, high reliability, and low power consumption of 2D imaging products.
The image recognition algorithm is perfectly integrated with advanced chip design and manufacturing technology, which greatly simplifies the production of 2D barcode reading
NNLS-EM20-EX Can read all kinds of mainstream one-dimensional bar codes and standard two-dimensional bar codes ( PDF417 , QRCodeM1/M2/Micro with Data Matrix Various versions). Also supports
reading GS1-DataBar TM ( RSS) Barcode, including Limited , Stacked , Expanded And other versions.
NNLS-EM20-EX Can easily read paper, plastic cards, LCD Various printing media and bar codes on display media are powerful. Its fully integrated design requires only a very small installation space and is
extremely lightweight, making it very easy to be embedded in various product applications.

Chapter 2 Supporting Tools
EasySet
EasySet Is a Windows It runs under the operating system and is a configuration software for equipment bar codes, communication and other parameters independently developed by Newland Automatic
Identification Company. It can pass EasySet Graphical interface settings or query device configuration, you can also directly interact with the device through instructions.

Chapter 3 System Settings
Introduction
There are three ways to set up the scanner:
Set code
The scanner sets options and functions by reading a series of special barcodes. In the following chapters, we will introduce in detail the options and functions available for setting and provide corresponding
Set the code.
This method of setting and reading is relatively straightforward. Since each setting code needs to be read manually, it is easy to make mistakes.
Set command
The host can send a setting command string to set the scanner. In the following chapters, in addition to introducing the setting code, we will also introduce the setting command string.
The scanner can be set up automatically using the setting command. The user can develop a set of software to load all relevant setting data into the scanner.
EasySet Set up
EasySet Is a Windows The image user interface program under the system is independently developed by Newland Automatic Identification Company for bar code reading and processing. use
EasySet You can view the decoded barcode information and the image taken by the scanner, and you can also set the scanner easily.
This setting method is very similar to the setting command. EasySet It is specially designed for the products of Newland Automatic Identification Company.
Tip: Except for some temporary settings that will disappear after the device is restarted or powered off, other function settings will be stored in the scanner and will not be lost due to shutdown.

Startup settings
Set logo
This is a sign to disable the setting code function.
The logo consists of four parts:
Set the barcode part of the code.
The setting command string corresponding to the setting code.
The name of the set option or function, such as exiting the setting function.
* * Indicates that this item is set as the default setting.

Use setting code
Read " Startup settings " Bar code to activate the setting code function. The scanning engine can be set by reading the setting code.
To exit the setting code function, just read " Exit settings " Bar code or set the bar code outside the code.

Setting code information
The setting code information can be sent to the host. The factory default setting is " Do not send configuration code information " , The setting code information will not be sent to the host at this time; " Send
setting code information " Barcode, the scanning engine will send the setting code information to the host.
