1. Introduction of Module
1.1 Introduction
MG66 Bar code reader module is a high performance
scanner, can read 1D bar code easily and read 2D bar code with
high speed. It also wins high scan speed for linear code, even for
bar code on paper or screen.
MG66 bar code reader module is an advanced bar code
decoding algorithm which developed on image recognition
algorithm, can easily and accurately read bar code, simplify
secondary development.
MG66 works stable in dark and large temperature range.

2 Communication interface
GM66 can receive database, control module and set functional parameter by TTL - 232.
2.1 Series Communication Interface
It’s default and common to connect module and mainframe(such as PC, POS) by series
communication interface. Make sure communication parameter for module and mainframe are same,
then it will communicate smooth and correctly.
Series Output
TTL-232 is used for series interface which suitable for most system. Required change-over circuit
for RS-232.
Default Parameter as formForm 2- 1. Only Baud Rate can be changed.
