4. Настройка
4.1 Фізічная ўстаноўка
The NF-B912 units are designed for pole-mounted installation. Ensure the units are securely fastened and positioned for optimal line-of-sight between the two bridge units for maximum range and performance.
4.2 Connecting the Devices
Each NF-B912 unit is powered via a Power over Ethernet (POE) adapter. Connect an Ethernet cable from the POE adapter's 'POE' port to the NF-B912's WAN port. Connect another Ethernet cable from the POE adapter's 'LAN' port to your network device (e.g., router, switch, NVR, or computer).
4.3 Initial Configuration and Pairing
The NF-B912 supports automatic bridge pairing for simple operation. Before powering on, set the mode switch on one unit to 'AP' (Access Point/Transmit Mode) and the other unit to 'STA' (Client/Receiving Mode). Once powered on, the units should automatically establish a wireless bridge connection.
5. Рэжымы працы і функцыі
5.1 Некалькі рэжымаў працы
The NF-B912 can operate in several modes to suit different network requirements:
- Рэжым моста: Establishes a point-to-point or point-to-multipoint wireless link between two or more networks.
- Рэжым кропкі доступу (AP): Allows wireless clients to connect to a wired network.
- Рэжым рэтранслятара: Пашырае радыус дзеяння існуючай бесправадной сеткі.
- Рэжым маршрутызатара: Functions as a basic router, providing network address translation (NAT) and DHCP services.
5.2 Індыкатары сілы сігналу
The unit features a 4-bar signal strength indicator light, allowing for accurate and intuitive alignment during installation. Adjust the direction and angle of the device until the maximum number of signal bars are lit for optimal performance.
- Very Strong: All 4 signal bars lit
- Моцны: 3 signal bars lit
- Сярэдні: 2 signal bars lit
- Дрэнна: 1 signal bar lit
Other indicators include Power, WAN, LAN, and WiFi status lights.
5.3 Бяспека сеткі
The NF-B912 incorporates features to ensure network security:
- Схаванне SSID: The wireless bridge function can be configured to hide the SSID, preventing unauthorized wireless terminals from searching for the network.
- Шыфраванне: Supports various encryption protocols to protect user network data.
- Anti-Hijack, Anti-Hacker, Anti-Trojan: Built-in protections against common network threats.
5.4 Web Інтэрфейс кіравання
The device can be configured and managed through a web-based interface. Access this interface by connecting a computer to the LAN port of the POE adapter and entering the device's default IP address in a web browser. The interface supports multiple languages (English, German, French, Italian, Spanish, Japanese) for ease of use.
6. Тэхнічнае абслугоўванне

- Check the power indicator light on the NF-B912 and the POE adapter.
- Пераканайцеся, што разетка працуе.
7.2 Няма бесправаднога злучэння
- Verify that both units are powered on and their respective mode switches are correctly set (one AP, one STA).
- Check the signal strength indicator lights. If they are low or off, adjust the alignment of the units to improve line-of-sight.
- Ensure there are no significant obstructions between the two units.
- If automatic pairing fails, try resetting both units to factory defaults using the RESET button and reconfigure.
7.3 Павольная хуткасць сеткі
- Check the signal strength indicators; a weak signal will result in lower speeds.
- Ensure the wired connections are 10/100Mbps compatible and cables are not damaged.
- Minimize interference from other 5GHz devices in the area.
- Check for any bandwidth-intensive applications running on the network.
7.4 Немагчыма атрымаць доступ Web Інтэрфейс кіравання
- Ensure your computer is directly connected to the LAN port of the POE adapter.
- Verify your computer's IP address is in the same subnet as the NF-B912's default IP address (or configured IP).
- Паспрабуйце ачысціць кэш браўзера або скарыстацца іншым браўзерам.
- Калі IP-адрас быў зменены і забыты, можа спатрэбіцца скінуць налады да заводскіх.
8. Карыстальніцкія парады
- For optimal performance, always ensure a clear line-of-sight between the two bridge units. Even small obstructions like trees can degrade signal quality over long distances.
- When setting up, use the signal strength LEDs to fine-tune the aiming of each unit. Small adjustments can make a big difference.
- Consider using shielded Ethernet cables for outdoor installations to protect against environmental factors and electrical interference.
- Regularly check the manufacturer's support page for firmware updates, which can improve stability and add new features.
