التعبئة

1. One communication module host
2. 2 dedicated frequency band (1.4غيغاهرتز) الهوائيات (depending on different models, other types of antennas are optional)
3. 4 general frequency band (5غيغاهرتز) الهوائيات (depending on different models, other types of antennas are optional)
4. 1 GPS/BD antenna (depending on different models, other types of antennas are optional)
5. One 100M network port conversion cable (airline plug to RJ45 network port)
6. 1 serial port conversion cable (aviation plug to RS232 serial port)
7. DC 24V adapter 1 (aviation plug 2 cores)

1.3 Installation steps

1. Install the self-organizing network antenna: connect the dedicated frequency band antenna (or feeder) to the N head (درجة المسافة الاختيارية, درجة المسافة الاختيارية), press and rotate to fix it, and ensure that the antenna is tightened and not loose;
2. Install the 5G antenna: connect the 5G frequency band antenna (or feeder) to the SMA head (درجة المسافة الاختيارية, درجة المسافة الاختيارية, ANT3, ANT4), press and rotate to fix it, and ensure that the antenna is tightened and not loose;
3. Install the Beidou antenna: Connect the Beidou antenna (or feeder) to the SMA head (ANT7), press and rotate to fix it, and ensure that the antenna is tightened and not loose;
4. Install the network port conversion cable: connect the network cable to the host aviation seat (DATA1), and ensure good contact after plugging in; (5). Install the serial port conversion cable: connect the network cable to the host aircraft seat (RS232), and insert it tightly (6). Install the power cord: Connect the DC 24V power supply to the host aviation seat (العاصمة) through the aviation plug (2 cores), and then tighten the nut to ensure good contact.

1.4 Boot steps

(1). Press the switch, turn on the power, the indicator light of the power switch (قوة) is on, and the system starts self-test (It is forbidden to turn on the power without connecting the antenna, and it forbidden to use other types of adapters)

Precaution

• Make sure the antenna is tightened;
• Keep the antenna vertical to the ground during the test;
• Do not touch the antenna with your hands or other objects during the test;
• It is not advisable to get too close to each other between devices, and they should be separated by more than 5M;
• If there are test conditions, choose a commanding height to erect one of the nodes;
• Check whether the communication link is normal through the network indicator light, and the network indicator light is always on, indicating that the link layer has been successfully connected;
• Check the environmental noise situation through the WEB interface to know whether there is co-channel interference around;
• حول 5 seconds after the networking is successful, you can check the network connectivity of each node through the ping packet;
• Make sure that the cameras, أجهزة الكمبيوتر, and other devices that need to be connected are in the same IP address segment, and can communicate normally under the condition of a wired connection, without using the same address segment of NexFi devices (NexFi devices communicate through MAC addresses);
• Traffic flow, people flow, البنايات, and trees will have varying degrees of impact on communication quality;
• When doing penetration tests inside and outside the building, the external nodes should not be too close to the building, and the distance should be more than 10M;
• If you need to achieve a longer test distance, you can adjust the bandwidth to 2Mhz through the management interface, and if you need to achieve a larger bandwidth, you can adjust it to 20Mhz;
• If it is used for video transmission, in order to avoid video freeze, you can optimize the video effect by adjusting the camera resolution, frame rate, transcoding stream, and other parameters;
• If used for open-air day and night testing, please take waterproof measures and ensure good heat dissipation contact.
