work mode of rs485 to ethernet converters: tcp server mode

Work mode

TCP Server

RS485 to Ethernet converters USR-TCP232-304 monitor the set port and wait for a TCP client connection.
Data from the serial device will transmit to all successfully-connected TCP clients via USR-TCP232-304.

work mode of rs485 to ethernet converters: tcp client mode

TCP client mode

RS485 to Ethernet converters USR-TCP232-304 initiate TCP connection to the destination IP address that
configured by the user and USR-TCP232-304 continuously try to reconnect if establishing TCP connection
unsuccessfully. If USR-TCP232-304 establishes TCP connection to TCP Server successfully, it can realize
bidirectional data transparent transmission between TCP Server and the serial device.

work mode of rs485 to ethernet converters: UDP mode

UDP mode

RS485 to Ethernet converters USR-TCP232-304 will transmit serial data from serial
device to target network device by UDP connection. USR-TCP232-304 will listen to port
and transmit all received data to serial device.

work mode of rs485 to ethernet converters: httpsD Client

httpsD Client

RS485 to Ethernet converters USR-TCP232-304 support https Client mode which can transmit serial data
to the https server in https format(GET/POST).

Synchronous Baud Rate

Synchronous Baud Rate

Dynamically change baud rate, data bit, check bit and stop bit of USR-TCP232-304 via network command.

Identity packet function of ethernet to rs485 converters

Identity packet function

When RS485 to Ethernet converter USR-TCP232-304 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.
