Onboard multiple function indicator lights, convenient to check the module communication and running status
Working mode optional TCP Server, TCP Client, UDP Server, UDP Client, HTTPD Client (support GET and POST)
Support Modbus gateway function, more convenient for industrial use
Support Websocket function, can realize two-way transparent transmission with RS232, RS485 port directly through webpage
Support web page, AT command, serial port protocol and network protocol setting parameters, provide setting protocol, customers can integrate into their own software
Support custom heartbeat packet mechanism to ensure the connection is true and reliable, and can also be used to actively capture sensor data
Support custom registration package mechanism, automatically send a predetermined registration package as a logo after establishing a connection, which is convenient to distinguish different devices
Support custom web page function, convenient for users to customize module web page content
Supports RFC2217-like protocol, which can communicate with devices with variable serial port parameters (baud rate, data bits, etc.)
Support KeepAlive mechanism, can quickly detect abnormal network interruption, and disconnect and reconnect
Support timeout restart (no data restart) function to ensure long-term stable communication, and can customize restart time
Support DNS domain name resolution function, can customize DNS server address
Support DHCP function, can automatically obtain IP, can also customize static IP
Support the function of upgrading firmware through the network, making maintenance more convenient
Support to restore factory settings through software and hardware
