USR-DR302 DIN-rail RS485 Serial to Ethernet Converter
USR-DR302 Modbus RS485 to Ethernet converter can realize bidirectional transparent transmission between RS485 and Ethernet. Via web-page or software, rs485 to Ethernet Converter can realize serial data and TCP/IP data package transparent transmission.
Serial to Ethernet converter USR-DR302 will initiate TCP connection to the destination IP address that configured by the user and serial to Ethernet converter will continuously try to reconnect if establishing TCP connection unsuccessfully.
Serial to Ethernet converter USR-DR302 monitors the set port and waits for a TCP client connection. Data from the serial device will transmit to all successfully-connected via serial to Ethernet converter.
USR-DR302 only communicates with the target interface of the target IP, thus to assure the accuracy of data transmission.
DR302 can transmit the data automatically to the last time transferred device after receiving the data, which is suitable for multi-network devices that need to communicate with the DR302.
DR302 supports the function of transmitting the serial data to the specified server in the form of HTTPD (GET/POST).
