USR-TCP232-304 is a low-cost serial converter, widely used in the solution of serial data networking communication.
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.
Realize bidirectional communication between RS485 and Ethernet.
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.
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 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.
304 supports HTTP Client mode which can transmit serial data to HTTP server in HTTP format(GET/POST).
Connect to USR-VCOM’s virtual serial port.
User can dynamically modify 304’s serial parameters by network commands.
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.
Connect serial to ethernet converter USR-TCP232-302 to barrier gate and it can realize remote control of barrier gate by Ethernet in control center.
Can realize data transparent transmission to network and real-time monitoring.
Can realize remote and real-time data transmitting.
Stable network-based management and save human cost.
Connect 302 to traffic lights and it can realize traffic data acquisition and processing by Ethernet in control center.
Can implement the optimum control for transportation phenomena such as traffic jam, traffic accident, traffic capacity from a regional or global perspective.
