Function Diagram
Work mode
TCP Server
Ethernet to serial converters USR-TCP232-306 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-TCP232-306.
TCP client mode
Ethernet to serial converters USR-TCP232-306 will initiate TCP connection to the destination IP address that configured by the user and USR-TCP232-306 will continuously try to reconnect if establishing TCP connection unsuccessfully. If the USR-TCP232-306 establishes TCP connection to TCP Server successfully, it can realize bidirectional data transparent transmission between TCP Server and the serial device.
UDP mode
Ethernet to serial converters USR-TCP232-306 will transmit serial data from serial device to target network device by UDP connection. USR-TCP232-306 will listen to port and transmit all received data to serial device.
httpsD Client
Ethernet to serial converters USR-TCP232-306 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 USR-TCP232-306 via network command.
Serial & Network Heartbeat Packet
USR-TCP232-306 maintains the normal connection with the server by sending heartbeat packet regularly.
USR Cloud
IOT Cloud platform that is developed by our company independently.
Application
[ Unattended Weighing ]
Connect Ethernet to serial converters USR-TCP232-306 to barrier gate and they can realize remote control of barrier gate by Ethernet in control center.
[ Traffic Lights Management System ]
Connect Ethernet to serial converter USR-TCP232-306 and it can realize traffic data acquisition and processing by Ethernet in control center. It can also provide accurate quantitative basis for traffic dispatch management and urban transport planning Can implement the optimum control for transportation phenomena such as traffic jam, traffic accident, traffic capacity from a regional or global perspective.
