4. Connect Serial Device (RS485): Connect your RS485 device to the A(+) and B(-) terminals on the RS485 terminal block. Ensure correct polarity.

4.2. 초기 네트워크 구성

The device typically comes with a default static IP address, often 192.168.0.7 or 192.168.0.6. 액세스하려면 web 설정을 위한 인터페이스:

1. PC 연결: Ensure your PC is on the same network segment as the device. You may need to temporarily set your PC's IP address to be in the same subnet (e.g., 192.168.0.x, where x is not 6 or 7).
2. 입장 Web 인터페이스: 열기 web browser and enter the device's default IP address (e.g., http://192.168.0.7) 주소 표시줄에 입력합니다.
3. 로그인: The default username and password are often 관리자 / 관리자.
4. 네트워크 설정 구성: Once logged in, navigate to the network settings to configure the IP address, subnet mask, gateway, and DNS settings according to your network environment. You can choose between static IP or DHCP.
5. 직렬 설정 구성: Adjust the serial port parameters (baud rate, data bits, stop bits, parity) to match your connected serial devices.

For advanced configuration or if the web interface is inaccessible, use the provided USR-VCOM virtual serial port software or other configuration tools available from the manufacturer's web대지.

5. 작동 모드

The USR-TCP232-410S supports various operating modes to suit different application requirements:

• TCP 클라이언트 모드: The device initiates a connection to a specified TCP server. Data from the serial port is sent to the server, and data from the server is sent to the serial port.
• TCP 서버 모드: The device listens for incoming TCP connections. Multiple clients can connect, and data is transparently transmitted between the serial port and the connected clients.
• UDP 모드: Data is transmitted using the UDP protocol. This mode is connectionless and suitable for applications where speed is prioritized over guaranteed delivery.
• UDP 서버 모드: The device listens for UDP packets on a specified port.
• HTTPD Client Mode: Allows the device to send serial data to a web server via HTTP requests.
• Modbus RTU to Modbus TCP: This mode enables seamless integration of Modbus RTU serial devices into a Modbus TCP/IP network. The device acts as a gateway, converting RTU frames to TCP frames and vice-versa. It also supports multi-host Modbus polling.
• MQTT/TCP/UDP/HTTP for IoT Cloud: The device can collect data from Modbus RTU/TCP and report it to IoT cloud platforms in JSON format using MQTT, TCP/UDP, or HTTP protocols. This includes support for up to 128 data points and data decoding/computation to reduce server load.
• SSL/TLS Encryption: For secure data transmission, the device supports SSL/TLS encryption in TCP client, HTTP client, and MQTT operation modes, including two-way certificate authentication.
