1.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.

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
