RS485 Serial to Ethernet Converter
USRIOT Serial to Ethernet Converter, also known as Serial to Ethernet Server or Serial Device Server, which can realize bidirectional transparent transmission between RS232/RS485/RS422 and Ethernet. By way of setting web-page or software, USRIOT Serial to Ethernet Converter can realize serial data and TCP/IP data package transparent transmission.
USR-TCP232-304 is a low-cost serial converter, widely used in the solution of serial data networking communication.
Introduction of RS485 Ethernet Converter
USR-TCP232-304 is a low-cost serial RS485 Ethernet converter, which can realize bidirectional transparent transmission between RS485 and local Ethernet or Internet. It is integrated with TCP/IP protocol.

Provide PC TCP/IP socket programming example such as VB,C++,Delphi,Android and IOS
Realize bidirectional communication between RS485 and Ethernet.
Application Field of RS485 Ethernet Converter
Industrial data transmission, industrial automation
security and protection monitoring, public security
Smart home, power control, environmental monitoring, intelligent agriculture
Door check on work attendance system, POS system, rice selling system
Building automation system, power monitoring, self-service banking system, telecom machine room monitoring
TCP Server mode:
304 will listen to port that configured by user and wait to TCP Client connection.
304 will transmit data from serial device to all connected TCP Clients by transparent transmission.
PC initiates and establishes connection
304 realizes bidirectional data transmission between serial device and TCP Client
TCP Client mode:
304 will initiate TCP connection to destination IP address that configured by user and 304 will continuously try to reconnect if establishing TCP connection unsuccessfully.
If 304 establishes TCP connection to TCP Server successfully, it can realize bidirectional data transparent transmission between TCP Server and serial device.
304 realizes bidirectional data transmission between serial device and TCP Server
304 will transmit serial data from serial device to target network side device by UDP connection.
304 will listen to port and transmit all received data to serial device.
304 realizes bidirectional data transmission between serial device and network side
HTTP Client mode
304 supports HTTP Client mode which can transmit serial data to HTTP server in HTTP format(GET/POST).
USR-VCOM with powerful function:
Connect to USR-VCOM’s virtual serial port.
Web Server with powerful function
Baud rate synchronization function:
User can dynamically modify 304’s serial parameters by network commands.
Identity packet function:
When 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.
Network heartbeat packet: 304 can send heartbeat packet to network server periodically to inform server that 304 is in active status and to keep normal network connection with server.
Serial heartbeat packet: 304 can send heartbeat packet to serial device periodically to inform serial device that 304 is in active status and serial heartbeat packet can also be used to grab sensor data.
IoT cloud platform that being developed by USRIOT independently.
