[working mode]: [tcp server]: rs485 to port set by usr Ethernet converter - tcp232 - 304 to monitor and wait for TCP client to connect. Serial device data will be transmitted to all successful connected TCP clients via usr - tcp232 - 304. [tcp client mode]: Rs485 to Ethernet converter usr - tcp232 - 304 initiates TCP connection to the destination IP address configured by the user. if the TCP connection fails, the usr - tcp223 - 304 will continue to attempt to reconnect. If usr - tcp232 - 304 successfully establishes a TCP connection with the tcp server, a transparent two-way data transmission can be achieved between the TCP server and the serial device. [udp mode]: the rs485 to Ethernet usr converter - tcp232-304 will transmit serial data from the serial device to the target network device through the udp connection. Usr - tcp232 - 304 monitors the port and transmits all received data to a serial device. [httpsd client]: rs485 to Ethernet usr converter - tcp232 - 304 supports https client mode and can transmit serial data to https server in https format (get / post). [identity packet function]: When the rs485 to the usr Ethernet converter - tcp232 - 304 works as a tcp client, it can send identity packets to the TCP server and can perform the identification. Identity packets can be imei codes, iccid codes and user-editable identity packets. [application] [weighing unattended] by connecting usr - tcp232 - 304 to the fence gate, the remote control of the fence gate can be realized via Ethernet in the Control Center. [traffic light management system] by connecting rs485 to the Ethernet converter usr - tcp232 - 304, the acquisition and processing of traffic data over Ethernet can be performed in the Control Center.
