Realize bidirectional transparent transmission between RS232 and Ethernet
Small size, easy to manage and maintain, cost-effective
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.
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.
USR-DR301 only communicates with the target interface of the target IP, thus to assure the accuracy of data transmission.
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.
DR301 supports the function of transmitting the serial data to the specified server in the form of httpsD (GET/POST).
Solve the problem of PC software as a serial port can not communicate with networking device.
Serial server maintains the normal connection with the server by sending heartbeat packet regularly.
When 301 works as TCP Client, it can send identity packet packet to TCP server which can be identification. Identity packet can be IMEI code, ICCID code and user editable identity packet.
USR-DR301 can realize the bidirectional transparent transmission between the server and terminal device through USRIOT Cloud quickly.
