Catatan: Setelah menghubungkan antena terlebih dahulu, turn on the power and start software configuration and debugging. After the antenna is connected, the parameters can be monitored in real time.

Airborne interface description

1. Computer settings

Connect the device to the computer, check the device IP address in the computer’s network connection and the same network segment as the device address (below pictures). If you do not know the device computer, you can set the computer to automatically obtain IP, then check the computer network connection status for the device IP address, and then set On the same network segment, it is best to turn off the Windows Firewall on computers.

2. Run parameter configuration software

After opening the 1400_TDD_COFDM_ConfigV3.3 perangkat lunak, the main interface appears:

2.1 Power on the device and connect it to the computer

Enter the device’s IP address in the IP Address Login window on the right.

Here you can enter the IP address of the local device or the IP of the remote device. After multiple devices are successfully connected, the IP of any terminal can be used.

Click ConnectTDD to connect. Or directly click Connect last IP to log in quickly.

2.2 Login and network settings

Catatan: It takes about 3~5 seconds for the device to start up after powering on. Setelah mengklik connectTDD,

2.3 Monitoring information

• Before setting parameters, you need to look at the frequency electromagnetic environment. The lower the noise floor, lebih baik. The terminal access field strength and signal-to-noise ratio.
• After the parameters are successfully set, they will be displayed in the corresponding column. You can check whether the setting mode is correct.
• Displays the signal-to-noise ratio of the connection, kekuatan sinyal (antena 1, antena 2) and background noise.
• If the background noise is too loud, it means the interference is serious and you need to change the frequency band.
• You can carry a spectrum analyzer with you to test interference on site.
• Note that the data here is one-to-one, data in master-slave mode. For detailed data on each terminal in one-to-many or MESH mode, please refer to RF STATUS related data.

Display wireless related data:

Mode, ID number, Bandwidth, frekuensi, power and other data. Data related to the connected device, device number, SNR, RSSI, Noise Floor and other data.

• Displays the signal-to-noise ratio of the connection, kekuatan sinyal (antena 1, antena 2) and background noise.
• If the background noise is too loud, it means the interference is serious and you need to change the frequency band.
• You can carry a spectrum analyzer with you to test interference on site.
• Note that the data here is one-to-one, data in master-slave mode. For detailed data on each terminal in one-to-many or MESH mode, please refer to RF STATUS related data.

3. Pengaturan parameter

Setelah masuk, Anda dapat menampilkan dan mengatur data terkait perangkat.

1. Atur metode modulasi, kekuasaan, Bandwidth, frekuensi, jarak, dan modus.
2. Bandwidth modulasi: 2, 4, 8MHz
3. Pengaturan frekuensi: 1430-1444
4. metode modulasi: BPSK FEC 1/2, FEC QPSK 1/2, FEC QPSK 3/4, 16-QAM 1/2, 16QAM 3/4, 64QAM 2/3, 64QAM 3/4, 64QAM 5/6, MOBIL (biasanya diset ke BPSK FEC 1/2, QPSK FEC selama pergerakan 1/2)
5. Menyetel metode modulasi yang lebih tinggi akan mengirimkan jumlah data yang lebih besar, tetapi sensitivitasnya akan lebih rendah. Jika host mengirimkan data dalam jumlah besar dan budak memiliki data dalam jumlah kecil, tuan rumah dapat mengatur 16-QAM, budak BPSK, dan pengaturan asimetris. Jika jumlah datanya tidak diketahui, Besarannya bisa diatur ke AUTO. Mungkin lebih stabil jika Anda menentukan metode modulasi.
6. Jarak Nirkabel: Jarak antar terminal. Nilai ini sangat penting, terutama untuk transmisi jarak jauh. Nilai yang sesuai harus diisi. Jika SNR dan data lainnya normal tetapi rate-nya rendah, Anda dapat meningkatkan nilai ini.
7. MODE RF: Menguasai (tuan rumah) Budak (budak) UNTUK INI (menyampaikan) MESH (tidak ada jaringan pusat)
   • Master-slave mode: One master corresponds to one slave (one-to-one mode) or one master can correspond to multiple slaves (one-to-many mode).
   • AD-HOC mode: One host corresponds to multiple AD-HOC slaves. AD-HOC slaves can also communicate with each other. The number of standbys is more than that of MESH mode, and the delay and amount of data transmitted are less than that of MESH mode.
   • One host corresponds to multiple AD-HOC slaves, and then corresponds to multiple slaves, forming a mixed network.
   • MESH mode: Center-less networking, multiple MESH terminal networking (many-to-many mode)
   • MESH Path Agility: Network path stability optimization, can be set to High; Sedang; Rendah,
   • When a network node discovers a new network path, a path table will be created at each node and automatically optimized.
   • Namun, adding or reducing nodes will cause some problems, seperti: the connection needs to be re-established and the path table updated, and the link may be temporarily interrupted.
   • Di satu sisi, the entire link needs to retain the stability of the original link, and on the other hand, the path table needs to be refreshed to adapt to the changing network. Karena itu, this parameter is used when a new network is added or the signal of a single network is poor. The sensitivity of the path update path table. Medium is generally set, and is actually set according to engineering experience. The internal parameters can be seen in the RF STATUS on the right.
8. Narrow-band data (serial port data) Pengaturan

UART setting page, Set UART serial port related data here:

• Tick ​​the box and select the parameters for the corresponding settings
• Remote IP Addr: The other party’s IP address (sebagai contoh, 192.168.55.2)
• Remote port: Nomor pelabuhan (fill in the following 20002, or you can customize it)
• Listening port: Nomor pelabuhan (fill in the following 20002, or you can customize it)
