Serial Device Server Introduction

USR-N520 is a double serial device server, which can realize transparent transmission between TCP/UDP data package and RS232/RS485/RS422 interface. The device has unique functions such as network printing, Modbus multi-host polling and watchdog mechanism. USR-N520 is based on ARM processor and it is internally integrated with TCP/IP protocol.User can easily realize embedded device networking.

Serial Device Server Features

  • TI Cortex-M4 solution, ARM processor and TCP/IP protocol stack
  • Reload button,one key to restore factory defaults
  • Multiple indicator LEDs for easy debugging
  • DNS, DHCP, Websocket and HTTPD Client supported
  • Keepalive function,rapidly detect dead links
  • Built-in webpage, support customized
  • Can upgrade firmware via network easily
  • Account and password to page login and network settings
  • Support UDP broadcast,send and receive data from all IP in LAN
  • Global unique MAC address bought from IEEE, can be defined
  • Virtual serial port, setup and test software is availiable
  • Provide PC TCP/IP SOCKET programming example: VB, C++, Delphi, Android, IOS
