Package Include
(1). One ad hoc network host
(2). 2 dedicated frequency band (1.4Ghz) antenas (depending on different models, other types of antennas are optional)
(3). Common frequency band (2.4Ghz/GPS Beidou) antena (elegir 1 de 2)
(4). Power supply/network port conversion cable 1 pedazo
(5). Voice/RS232 transfer cable 1 (elegir 1 de 2)
(6). DC 12V adapter 1pc
Installation steps
1. Instalar la antena: connect the dedicated frequency band antenna (or feeder) to the TNC head (RF1/RF2), press and rotate to fix it, and ensure that the antenna is tightened and not loose;
2. Install the power supply/network port conversion cable: connect the aviation plug (2 cores) to the main engine aviation seat, and then tighten the nut to ensure good contact.
Boot steps
- Press the switch, turn on the power, the indicator light of the power switch is on, and the system starts self-test (It is forbidden to turn on the power without connecting the antenna, and it is forbidden to use other types of adapters）
- After the self-inspection is completed after the neighbor node is found, the self-organizing network indicator is always on, indicating that the network is successfully established
Redes
The networking indicator light indicates the status of being in the network or being disconnected from the network. When the indicator light is on, it indicates that the network has been established. Green indicates that the network quality with neighboring nodes is good, orange indicates normal, and red indicates poor quality.
| número de serie | estado | significado |
| 1 | light off | offline |
| 2 | green steady | good network quality |
| 3 | Orange is always on | Average network quality |
| 4 | Rojo fijo | poor network quality |
Precauciones
- 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;
- About 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, PC, 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, edificios, 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 5Mhz 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, velocidad de fotogramas, transcoding stream, y otros parámetros;
- If it is used for open-air day and night testing, please take waterproof measures and ensure good heat dissipation contact.
