Low-Cost RS232 Serial to Ethernet Converter

Basic Function

Function Diagram

Work mode

TCP Server

Serial device server monitors the set port and waits for a TCP client connection.
Data from the serial device will transmit to all successfully-connected via serial device server.

TCP client mode

Serial device server will initiate TCP connection to the destination IP address that configured by the user
and serial device server will continuously try to reconnect if establishing TCP connection unsuccessfully.
If the serial device server establishes TCP connection to TCP Server successfully, it can realize
bidirectional data transparent transmission between TCP Server and the serial device.

UDP mode

Serial device server will transmit serial data from serial device to target network device by UDP connection.
Serial device server will listen to port and transmit all received data to serial device.

HTTPD Client

Supports HTTP Client mode which can transmit serial data to the HTTP server in HTTP 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 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.

Serial & Network Heartbeat Packet

Serial server maintains the normal connection with the server by sending heartbeat packet regularly.

Application

[ Unattended Weighing ]

Connect serial to ethernet converter USR-TCP232-306 to barrier gate and it can realize remote control of
barrier gate by Ethernet in control center.
