2. Software Configuration
Follow the 8 steps in the figure below to get the gateway run for testing.
(1) Connect the gateway and the computer to a local area network through a switch or directly, and the
gateway default IP is 192.168.1.125. Set the IP address of the computer to the same CIDR segment,
such as 192.168.1.10
(2) Open a browser such as Google Chrome and type 192.168.1.125. in the address bar. Then enter the
login page, enter the default username admin and default password admin to enter the settings.
(3) Serial port settings: configure baud rate, data bits, etc. according to the parameters of the actual serial
device.
Choose different modes according to the actual serial port type.
Here the serial port is default, and the gateway serial port
communicates with the slave serial device as the master station.

(4) Network settings: The gateway should be in the same LAN as the ModbusTCP device and can ping
each other
（5）Modbus settings: set the Modbus listening port and map the address by default.
（6）For each setting page above, you must click Restart after modifying the parameters to take effect
Set network port parameters. You can modify IP and other parameters according to the
actual network.
The Listener port is the port of ModbusTCP connects to the
gateway for ModbusTCP communication.
Default setting. you can set the mapping of real addresses to
virtual addresses at will.
After every time you click Settings on another page, click Restart on this page for it to take effect.
