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 firewall and antivirus software.
（2）Configure the network card that is connected to the device.
（3）For PC direct serial port servers, you need to set up a static computer and maintain the
same network 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 debugging assistant software.
（2）The network settings area 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), click Create.
（3）Wait for the computer to connect to the serial server, the connection is complete after the
serial server M0 (green LED lit).
Figure 2- 3 Gate parameter configuration
（4）Open serial assistant, serial port rate is set to 115200, serial parameters are set to
None/8/1, click on open, open serial port.
