Introduction
This MG8322 Modbus gateway provides the ways of connecting serial devices to
Ethernet. It is designed to operate serial ports through Ethernet (10/100Mbps)
over TCP/IP network. As the data is transmitted via Modbus protocol, therefore
data acquisition and controlling is available to go through Intranet and
Internet. There are two serial ports as one is a RS-232 and other one is
RS-422/485. Configuration is easy to operate via web page setup.
This Modbus gateway is a high performance design composed with carefully
selecting qualified components from reliable and certified sources. This
operation manual will guide you to configure functions step by step.
This Modbus gateway provides RTU to TCP Slave, ASCII to TCP Slave ,TCP to RTU
Slave , TCP to ASCII Slave Mode, and it also supports manual configuration via
web browser.

Configuration
2.1Configuration Via Web
Step1➔ The first thing is to configure the Host PC’s IP address
IP :192.168.0.xx
Step2➔ Open a web page of configuration http://192.168.0.100
Step3➔ Default User name: “admin” and Password: “Leave it Blank”
Step4➔And now you have successfully connected to this Modbus gateway

2.2.5 Reset Button
If any chance you forgot the login password or have incorrect settings making
this Device inoperable, upon the power is on and the “SYS” LED light on, use a
point tip to press this button and hold it for more than 20 seconds the
