4.2 Сериялык порт

The device features a DB9 male connector for RS232 and a terminal block for RS485/RS422 connections. The serial mode is selected using the DIP switches.

5. Орнотуу

5.1 Кубат туташтыруу

Connect the provided power adapter to the DC input port of the USR-N510. Ensure the power source matches the specified voltage range (DC 5-36V). The PWR LED should illuminate once power is supplied.

5.2 Тармактык туташуу

Connect an Ethernet cable from your network switch or router to the Ethernet port on the USR-N510. The Ethernet link/activity LEDs on the port should indicate a successful connection.

5.3 Serial Port Configuration and Connection

The USR-N510 supports RS232, RS485, and RS422. The serial mode is selected using the DIP switches located on the device. Refer to the diagram below for proper switch settings and wiring.

Figure 5.1: Serial Port Wiring and DIP Switch Settings

5.3.1 RS232 туташуусу

• DIP Switch Орнотуу: Ensure all DIP switches are in the 'down' position.
• Зымдар: Connect your RS232 device to the DB9 male connector. Standard pinouts apply (TXD, RXD, GND).

5.3.2 RS485 туташуусу

• DIP Switch Орнотуу: Ensure all DIP switches are in the 'up' position.
• Зымдар: Connect your RS485 device to the A+, B-, GND terminals on the terminal block.

5.3.3 RS422 туташуусу

• DIP Switch Орнотуу: Set the left DIP switch 'up' and the right DIP switch 'down'.
• Зымдар: Connect your RS422 device to the RX+, RX-, TX+, TX-, GND terminals on the terminal block.

5.4 Программанын баштапкы конфигурациясы

The USR-N510 can be configured via a web browser or dedicated setup software. Typically, the device obtains an IP address via DHCP by default. If DHCP is not available, it will use a default static IP address (refer to the product's specific documentation for the default IP).

1. Connect your PC to the same network as the USR-N510.
2. ачуу а web browser and enter the device's IP address.
3. Log in using the default username and password (refer to the product's specific documentation).
4. Configure serial port parameters (baud rate, data bits, stop bits, parity) and network parameters (working mode, remote IP/port) as required for your application.

6. Иштөө нускамалары

6.1 Basic Data Transmission

Once configured, the USR-N510 operates as a transparent data channel. Data sent to the serial port will be encapsulated and transmitted over Ethernet, and vice-versa. The specific behavior depends on the configured working mode (e.g., TCP Client, TCP Server, UDP).

6.2 Modbus RTU to TCP Gateway

In Modbus RTU to TCP mode, the converter acts as a gateway, translating Modbus RTU commands received on the serial port into Modbus TCP packets for the Ethernet network, and vice-versa. This allows Modbus TCP masters to communicate with Modbus RTU slave devices.

6.3 Watchdog Functionality

Figure 6.1: Watchdog and Core Processor

The USR-N510 incorporates a hardware watchdog circuit. This feature continuously monitors the device's operation. In the event of a system crash or unresponsiveness, the watchdog automatically triggers a reset, ensuring the device recovers and resumes normal operation without manual intervention. This is crucial for maintaining uptime in critical industrial applications.
