1. series 32-bit ARM processor is adopted, the main frequency is up to 120MHz, the running speed is fast, stable and .2. Support 10/100M Ethernet interface, support Auto-/MDIX (any connection with crossover direct connection cable, automatic switching).3. Support RS232 and RS485 interfaces, the two interfaces can work independently at the same time without affecting each other. 4. Support setting the communication rate (600bps~230.4Kbps), support None, Odd, Even, and Space checksums.5. On-board function indicators, easy to check the module communication and running status.6. The working mode can Server, Client, UDP Server, UDP Client, HTTPD Client (support and POST)7. Support Modbus function, more convenient for industrial use. 8. Support Websocket function, which can realize two-way transparent transmission with RS232 and RS485 ports directly through the web page. 9. Support web page, AT , serial port protocol and network protocol setting parameters, setting protocol, customers can integrate into their own software.10. Support custom packet mechanism to true and connection, and can also be used to actively capture sensor data 11. Support the custom registration package mechanism, automatically send a predetermined registration package as an identifier after the connection is established, which is convenient for distinguishing different devices.12. Support the function of custom web page, which is convenient for users to customize the content of the module web page. 13. Support RFC2217-like protocol, which can realize communication with devices with variable serial port parameters ( rate, data bits, etc.). 14. Support KeepAlive mechanism, which can quickly detect abnormal network interruption and disconnect and . 15. Support timeoutrestart (no data restart) function to long-term stable communication, and the restart time can be customized. 16. Support DNS domain name resolution function, can customize DNS server address. 17. Support DHCP function, can automatically obtain IP, and can also customize static IP. 18. Support firmware upgrade function through network, maintenance is more convenient 19. Support to factory settings by software and hardware 20. Factory-programmed specific , customizable address 21. software: module configuration software, /UDP test tools, virtual serial port software, etc. 22. programming examples: PC programming examples (socket), VB, C++, , Android, iOS, etc. parameter: Ethernet: Ethernet interface: 4-pin RJ45 Communication rate: 10/100Mbps Interface protection: with 2KV electromagnetic isolation Network protocols: IP, , UDP, , ICMP, DHCP, DNS, HTTPD Client, Websocket Send buffer: 16Kbyte Receive buffer: 16Kbyte RS485/RS232: Interface form: data bit: 5bit, 6bit, 7bit, 8bit RS485: Terminals (A+, B-, GND) RS232: DB9 pin male Stop bit: 1, 2 Check digit: None, Odd, Even, , Space rate: 600bps~230.4Kbps Send buffer: 2Kbyte Receive buffer: 2Kbyte Hardware flow control: / Colour:black Material:ABS+Metal Plug Type :EU Plug,it applies to Indonesia, , , , and so on.
