Double Serial Device RS232 RS485 RS422 Ethernet Server Modbus Multi-host Polling

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. 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 Support network printing Support Modbus multi-host polling Two ports can work independently at the same time Support Modbus RTU to Modbus TCP Serial baud rate from 600bps to 230.4K bps;Check bit of None,Odd,Even,Mark and Space DNS and DHCP supported Built-in webpage;also can customize webpage for users Reload button,one key to restore default settings 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 Two serial ports;each serial can work as rs232,rs485 or rs422;DB9 female;provide rs485/rs422 converter Two channel serial communication indicator: TX/RX Support DC adapter and 5.08-2 terminal power supply Support UDP broadcast function Parameter Input Voltage : DC 5 ~ 36V Operating Temp. : -40 ~ 85°C Storage Temp.: -45 ~ 105°C, 5 ~ 95% RH Network Protocol : IP, TCP, UDP, DHCP, DNS, HTTP, ARP,ICMP, Web socket, Httpd client
