4 Serial Port RS232/RS485/RS422 to Ethernet Converter

Introduction USR-N540, a four serial device server, can realize transparent transmission between TCP/UDP data package and RS232/RS485/RS422 interface. USR-N540, based on ARM processor, is of low power, rapid speed and high stability. And N540 is internally integrated with TCP/IP protocol. User can easily realize embedded device networking. Features Cortex-M4 kernel, industrial working temperature range and TCPIP protocol stack. Auto-MDI/MDIX, RJ45 port with 10/100Mbps TCP Server, TCP Client, UDP Client, UDP Server and HTTPD Client work mode Four ports can work independently at the same time Can distinguish which serial port connects to the device via port number Support virtual serial port and provide corresponding software USR-VCOM Serial baud rate from 600bps to 230.4K bps DNS and DHCP supported Provide PC TCP/IP socket programming example such as VB, C++, Delphi, Android and IOS Built-in webpage; also can customize webpage for users The global unique MAC address bought from IEEE (begin with D8-B0-4C); user can define MAC address Support upgrade firmware via network Support keepalive, rapidly detect dead links Support account and password, can be used to page login and network settings Support one channel Websocket, realize bidirectional transparent transmission between webpage and serial 0 Support Modbus RTU to Modbus TCP Support UDP broadcast function Four serial ports; each serial can work as rs232, rs485 or rs422; DB9 female; provide rs485/rs422 converter
