Working mode
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.
![Working mode of USR-DR301: TCP client](/d/file/20191030/5497b1d2cbcc0bc7ae549fe8182cc325.jpg)
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.
![Working mode of USR-DR301: TCP Server](/d/file/20191105/95888f7ccbbff3b0a8608dfdce9ca05e.jpg)
