6. Mga Pag iingat
   1. link performance

• 2.4GHz WiFi interference

The working frequency of WiFi is 2.4GHz, and the working bandwidth is 20MHz and 40MHz. WiFi will cause same-frequency or adjacent-frequency interference to the 2.4GHz wireless link of the drone. Even if there is no WiFi router nearby for the WiFi device to connect to, the WiFi device will periodically send a beacon/probe signal. Kaya nga, when you use the 2.4GHz wireless link to operate the drone in the field, you need to turn off the WiFi device (such as a modem, hotspot, at iba pa.) of the mobile phone or laptop. If the ground station needs to use a WiFi relay, it is recommended to use a 5.8GHz WiFI modem.

• Bluetooth interference

Bluetooth works in frequency hopping mode at 2.4GHz. Any Bluetooth device (such as Bluetooth mouse, Bluetooth joystick, car remote control key, at iba pa.) in working condition and close to the ground station will interfere with the downlink products. Please avoid using Bluetooth devices when operating the drone with a 2.4GHz wireless link.

• Wireless Device Coexistence Interference

If another wireless device works on a frequency close to 2.4GHz, when this device is close to the 2.4GHz module of the drone, it will interfere with the wireless link of the drone. Halimbawa, some drones use both LTE links and point-to-point communication links. Sa partikular na, it is important to note that LTE operating on the 2.3GHz frequency may also cause problems.

• HDMI interference

When the HDMI source/cable is close to the antenna of the 2.4GHz wireless device, the HDMI source/video will interfere with the 2.4GHz wireless signal (including WiFi).

https://h30434.www3.hp.com/t5/Notebooks-Archive-Read-Only/HDMI-interfering-with-WiFi-connectivity/td-p/4535026

http://www.dslreports.com/forum/r27141612-HDMI-connect-interferes-with-wifi 

It is recommended to install the antenna at least 24cm away from the HDMI source/cable. Using a good shielded HDMI cable is also a solution. The following shielded HDMI cables use 360-degree shielded terminations, which is recommended.

HDMI Cables and EMI

http://www.l-com.com/audio-video-micro-hdmi-to-hdmi-cables 

http://www.l-com.com/audio-video-hdmi-female-to-micro-hdmi-male-adapter 

• EMI of USB3.0 extender and splitter (HUB)

USB3.0 extender or splitter will cause EMI to the device, please check whether there is EMI when using USB3.0 extender to avoid interference to wireless devices.

• RF cable connection and antenna connection inspection

Before flying, check if the antenna is connected to the module. Using the module without the antenna connected will result in extremely short distances and may damage the module. It is recommended to check the connections of all RF connectors. Loose connections can significantly reduce distance.

• antenna installation

The placement of two antennas in the air ensures that no matter what the position of the drone, at least one antenna will not be blocked by the ground station payload. When installing the air end antenna, make it close to the vertical ground when the drone is moving.

• battery power

If the battery powering the module is low, transmit and receive performance will degrade, even though the battery may still be powering the module.

2. Remote control channel and remote control

The remote control channel of the wireless video link module supports PPM and S.BUS protocols. If you use the PPM protocol, you need to configure the remote control to PPM mode and turn off the wireless transmission of the remote control. If the S.BUS protocol is used, the wireless operating frequency of the receiver and the remote control must be in a different frequency band from the operating frequency of the wireless video link module, and a certain degree of isolation must be guaranteed.

If you do not use the remote control channel of the wireless video link module, but use the remote control link that comes with the remote control, you must pay attention to the working frequency of the remote control link of the remote control. If the working frequency of the wireless video link module is in the same frequency band, it will interfere with each other.

When using it, it is necessary to avoid the interference of the wireless link of the remote control or the receiver on the wireless video link module.

3. frequency selection

After the device is connected normally, open the wireless video link management software and click the “Dalas” button.

On the left side, you can observe the RSSI curve of the 2.4G WIFI frequency band scanning results.

The lower the RSSI value corresponding to the frequency point, the smaller the interference of the corresponding frequency point.

In order to ensure the best working performance, please select the frequency point with the least interference as the working frequency point.

The working mode provides two modes manual and automatic.

Manual mode: The user can manually configure the working frequency.

Automatic mode: After the device is turned on, it selects the working frequency according to the frequency scanning results.

Please use manual mode for manual frequency point configuration.

Use the channel selection function to configure the desired operating frequency.

4. firmware upgrade

Upgrade files: Air-end FPGA, Ground-end FPGA, Air-end MCU1 program, Ground-end MCU1 program, Air-end MCU2 program, Ground-end MCU2 program.

All files are updated using management software. Do not disconnect the power supply during the upgrade process, and ensure the normal connection of the USB cable. If the upgrade fails, do not disconnect the power or restart the device, please try to upgrade again directly. Kung hindi man, it will be necessary to return to the factory and use a special burning tool for firmware burning.

Tanong 16: After connecting the wireless video link device, nagyeyelo ang imahe o may mosaic phenomenon?

              1) Kumpirmahin kung ang pagsasaayos ng downlink mode ay makatwiran;

                 2) Nakakonekta ba nang maayos ang network cable na ginamit;

                 3) May panghihimasok man sa downlink, Isaalang alang ang pagbabago ng punto ng dalas ng pagtatrabaho;

                 4) Kung walang panghihimasok, naabot na ba ang limit distance ng communication link;

                 5) Obserbahan kung ang downlink rate ng pod fluctuates masyadong maraming. Halimbawa, ang fixed bit rate ng pod ay 3 Mbps, at ang downlink rate ng client ay naka set sa 3.97 Mbps, at ang peak value ng bit rate ng pod ay malamang na nasa isang tiyak na yugto Kung ito ay lumampas 3.97 Mbps, magkakaroon ng lag o mosaic phenomenon sa panahong ito. Itakda ang downlink rate ng kliyente sa 5.27 Mbps, at i verify kung lumampas ang downlink rate 3.97 Mbps. Kung ito ay lumampas sa 3.97 Mbps, itakda ang downlink rate ng client upang maging mas malaki kaysa sa peak value ng pod;

                 6) Suriin ang real time na rate ng downlink ng kliyente, may mga double camera stream man;

                 7) If none of the above operations can solve the problem, please contact wireless video link technical support personnel.

Tanong 17: Paggamit ng wireless video link equipment, maikli ang distansya ng komunikasyon, na hindi nakakatugon sa mga inaasahan?

              1) Kumpirmahin kung ang antenna at pagkonekta cable ay naka install nang tama at kung ang mga ito ay standard na materyales ng wireless video link;

                 2) Tiyakin na ang antenna installation ng air terminal ay hindi mahaharang ng load, at na walang halatang sagabal sa maikling distansya ng antenna ng ground terminal, at na ang antenna ng air terminal at ang ground terminal ay patayo sa lupa;

                 3) Check whether the video transmission equipment hardware such as power amplifier is damaged;

                 4) Kung ang halaga ng pagsasaayos ng mode ng downlink ay hindi makatwiran, at ang mataas na bilis ng downlink mode ay makabuluhang mabawasan ang distansya ng komunikasyon;

                 5) Kung ang nagtatrabaho dalas ay makabuluhang interfered, Maaari mong piliin ang pinakamainam na dalas sa pamamagitan ng client;

                 6) Kung ang air terminal at ang ground terminal ay malubhang naharang sa kapaligiran ng flight, at ang masalimuot na heograpikal na kapaligiran ay makakaapekto sa distansya ng komunikasyon;
