USR-DR301 DIN-rail RS232 Serial to Ethernet converter
USR-DR301 is a tiny size RS232 to Ethernet converter, which can realize the bidirectional transparent transmission between RS232 and Ethernet.
- RS232 Port: Terminal Type
- Industrial-grade, DIN-Rail mounting
- Modbus RTU to Modbus TCP
Work mode
TCP Client
Serial to Ethernet converter USR-DR301 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.
TCP Server
Serial to Ethernet converter USR-DR301 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.
UDP Client
USR-DR301 only communicates with the target interface of the target IP, thus to assure the accuracy of data transmission.
UDP Server
DR301 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 DR301.
HTTPD Client
DR301 supports the function of transmitting the serial data to the specified server in the form of HTTPD (GET/POST).
