1.Brief introduction of serial to Ethernet converter USR-DR302

Modbus RS485 to Ethernet converter USR-DR302 can realize bidirectional transparent transmission between RS485 and Ethernet. It carries ARM processor, low power, fast speed, high stability. Via web-page or software, rs485 to Ethernet Converter can realize serial data and TCP/IP data package transparent transmission.

 

2 Features of serial to Ethernet converter USR-DR302

  1. base on Cortex-M0 kernel, and reliable TCP/IP protocol stack
  1. working temperature range from -40C ~85C
  2. RJ45 port with 10/100Mbps
  1. TCP server, TCP client, UDP server, UDP client, httpsD client and modbus TCP work mode
  1. port baud rate can be set from 600bps to 460.8Kbps, parity: None, Odd, Even, Mark, Space
  1. self-defined heartbeat package, keep the connection can never crash
  2. self-defined registration package, check the station of the connection, which also can used as the self-defined package head, Users can use the MAC as the registration package.
  3. the TCP server mode, the number of the client connected to the server can be set from 1-8, default 4. the IP of the client connected can be dispaly. Each connection calculates the data received/transmitted.
  4. the TCP server mode, if the number of the clients number is 8, kick the old one or not can be set.
  1. the parameters via the webpage, AT command, serial protocol and net protocol, provides setting protocol, and users can put into their software.
  1. TCP client short connection, the disconnection interval can be set.
  2. timeout restart( no data and restart), the restart time can be set.
  3. the TCP connection build, client the buffer data or not can be set
  4. DHCP, obtain the IP automatically.
  5. global unique MAC address bought from IEEE, also users can define MAC address
  6. DNS function, and analyze the domain name. The DNS server address can be set.
  7. firmware via network.
  8. USR-VCOM
  9. hardware and software restore default settings
  1. across the gateway, converter and the router
  2. in LAN or in access the external net.
