Double serial port server USR-N520 is used to realize data transparent transmission between TCP/UDP datapackage and RS232/RS485/RS422 interface. Three in one serial port communicating code, support commonRS232/RS485/RS422 serial interfaces.
Features 1. ARM base on Cortex-M4 kernel, and reliable TCP/IP protocol stack 2. Industrial working temperature range from -40C ~85C 3. Auto-MDI/MDIX,RJ45 port with 10/100Mbps 4. Support TCP server, TCP client, UDP, UDP server and HTTPD client work mode 5. One port corresponding to two socket 6. Support network printing via IP address 7. Function of Modbus gateway, modbus RTU to modbus TCP, modbus multi-host Polling 8. Two serial port, each port can work as RS232 or RS485 or RS422 and work individually 9. Distinguish which serial port connect to device via port number 10. Support virtual serial port and provide corresponding software USR-VCOM 11. Serial baud rate from 600bps to 230.4K bps; Check bit of None,Odd,Even,Mark and Space 12. Support static IP, DHCP/DNS and search devices within network through UDP broadcast. 13. Provide serial and network setting protocol, TCP/IP socket example code such as VB, C++ Delphi,Android,IOS 14. Built-in web page; Customized web page is acceptable 15. Reload button,one key to restore default settings 16. RJ45 with Link/Data indicator light,built-in isolation transformer and 2 KV electromagnetic isolation 17. The global unique MAC address bought from IEEE, also user can define MAC address 18. Upgrade firmware via network 19. Support web port revise (80 by default) 20. Keepalive, detect dead links and reconnect rapidly 21. Support account and password, used to page log in and network settings safely 22. Support one channel Web socket,realize bidirectional transparent transmission between web page and serial side 23. Power supply in two mode, DC adapter or 5.08-2 terminal pin 24. Communication indicator light of two serial port: RX/TX 25. UPD broadcast function, can receive/send data to all IP in the same network
