Support RS232 and RS485 interfaces, the two interfaces can work independently at the same time, without affecting each other

Support to set the communication baud rate (600bps~230.4Kbps), support None, Odd, Even, Mark and Space five kinds of verification

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

Factory-programmed specificMAC, customizable MACaddress
