4.2 Menyambung Peranti

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).

NF-B912 Easy Installation and Port Layout — Figure 4: The bottom of the NF-B912 unit showing WAN, RESET, and LAN ports. The mode switch allows selection between STA (Client) and AP (Access Point/Transmit) modes.

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.

Sahkan bahawa salur keluar kuasa berfungsi.

7.2 Tiada Sambungan Tanpa Wayar

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 Kelajuan Rangkaian Perlahan

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 Tidak Boleh Akses Web Antara Muka Pengurusan

Cuba kosongkan cache penyemak imbas anda atau gunakan penyemak imbas lain.
If the IP address has been changed and forgotten, a factory reset may be necessary.

8. Petua Pengguna

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.
