Basic Function of 1 Port RS232 to Ethernet Converters
Function Diagram
Work mode
TCP Server
RS232 to Ethernet converters USR-TCP232-302 monitor the set port and waits for a TCP client connection.
Data from the serial device will transmit to all successfully-connected TCP clients.
TCP client mode
RS232 to Ethernet converters USR-TCP232-302 will initiate TCP connection to the destination IP address that
configured by the user and USR-TCP232-302 will continuously try to reconnect if establishing TCP connection
unsuccessfully. If the USR-TCP232-302 establishes TCP connection to TCP Server successfully, it can realize
bidirectional data transparent transmission between TCP Server and the serial device.
UDP mode
RS232 to Ethernet converters USR-TCP232-302 will transmit serial data from serial device to target network device
by UDP connection. USR-TCP232-302 will listen to port and transmit all received data to serial device.
httpsD Client
RS232 to Ethernet converters USR-TCP232-302 supports https Client mode which can transmit serial data
to the https server in https format(GET/POST).
Virtual Com Software
Synchronous Baud Rate
Dynamically change baud rate, data bit, check bit and stop bit of serial device server via network command.
Identity packet function
When RS232 to Ethernet converter USR-TCP232-302 works as TCP Client, it can send identity packet to TCP server
which can be identification. Identity packet can be IMEI code, ICCID code and user editable identity packet.
