2.2 The device is wired
Test serial-to-network data communication and connect the RS485 pin of the device to the PC
side via a USB serial converter.
Use a network cable to connect the device's gateway(RJ45)to the PC's gate.
The connection diagram looks like this:

2.3 Software settings
2.3.1 The network test environment
Avoid server search failures (pings don't work) and problems with customers not being able to
open web pages during real-world applications. Check the computer for the relevant settings first.
（1）Turn off your computer's fire walls and antivirus software.
（2）Configure the network card that is connected to the device.
（3）For PC direct-to-serial servers, you need to set up a static computer that remains the
same segment as the device.

2.3.3 Data transfer test
After the above steps, follow the device factory default parameters, do the following, to achieve
data transmission testing.
Here's how:
（1）Open the test TCP/IP debug assistant software.
（2）The network setup selects the TCP client mode, which corresponds to the server IP
address (module default target IP: 192.168.3.3). The server port number corresponds to the module
setting port 8887(module default port: 8887),clickCreate .
（3）Wait for the computer to connect to the serial server, and the M0 (green LED lights
up)of the serial server when the connection iscomplete.
