1. Must your price be 2X for TX and RX, correct?

Yes, for the two-way bidirectional wireless video data RC link, the quotation is on the base of one unit. If you need one transmitter and one receiver, then the unit price should be 2X. There are also customers who buy three or more sets; the middle one is the relay to extend the distance further. There are also customers with multiple transmitters and a receiver or one transmitter and multiple receivers. The quantity is according to your needs, so the cost is unit price X quantity.

2. What is the altitude estimates to achieve 50 km and 80 km?

The flying altitude of this drone depends on its actual application. The transmission distance we mentioned here is based on the visible range. LOS (line-of-sight). We have some clients who use weather balloons in the atmosphere (24-37km ) to monitor the operation and performance of the device. There are also more customers who use UAVs, just keeping the UAV higher than the obstacle on the grounds. In our test video on the ground, in order to test the transmission distance from 30 to 150 kilometers, it is often necessary to climb a high mountain of about 1,000 meters, so that the field of vision is wide.

7. What are the weights of 5 watts and 10 watts ?

TX900: 5 Watts: 142grams and 10 Watts 242 grams

8. What is the delay (latency) of 5 watts at 55 km and 80km?

200-300ms video (including a camera to monitor) 30-60ms data

10. How about video quality between using 800 MHz and 1.4 GHz? Which is better, 55 km or 80 km?

The video quality is the same at 55km and 80km. The working frequency should be chosen in accordance with your local frequency authorization policy. If your local has DVB-T / DVB-T2 digital tv, the frequency range is from 170~860MHz, then 1.4GHz is recommended. Try to avoid the frequencies already in use in the local area as much as possible to reduce interference and avoid image quality freeze or mosaic.

11. Can the frequency be set correctly by the software?

Yes, you can set the frequency at the software Web UI or via the parameter configuration board tool. The antenna and PA power amplifier are working in some frequency range. Their frequency range is fixed when customized. So you should also change the antenna and PA when you change the frequency is out of their frequency range. For example, when you tell us you agree the working frequency is 1.4G, then the antenna and PA will work well at the 1.4G, even if you can change the transmitter and receiver working frequency to 800Mhz, you also need to change 800Mhz antenna and PA.

12. Do you have 1.2 GHz? This is better considering GPS frequency.

TX900 has three frequency ranges that can be optional: 800MHz, 1.4GHz, and 2.4GHz. The Vcan1818 working frequency range can be preset according to your project needs.

13. If I buy the 5-watt 30km, can I upgrade in the future to a 55km or 80 km license?

When you buy it, the power amplifier and max transmission range are fixed, and can not be expanded by software upgrades, except that you change the hardware of the transceiver module and PA. The assembly is complex, so you'd better buy a totally new one.

14. It would be nice to double-check if we can change the following parameters without rebooting the UAV radio: frequency; Bandwidth, and power amplifier.

Please note that our wireless transmitter module supports a frequency band. Such as 1427.9~1447.9MHz (1.4G) or 806~826MHz (800MHz), or optional 2401.5~2481.5MHz (2.4G). You must choose 1.4G, 800MHz, or 2.4G when buying it. (the antenna and PA will be customized according to the frequency band). In the frequency band, there are many frequency points. For example, the 1.4G range is from 1427.90 to 1447.0MHz. Like Wi-Fi, the module will auto-select the frequency point with the best current signal as the transmission frequency point, so you don't need to manually modify the frequency point unless you want to change to a frequency point with the worse signal. So our engineer doesn't suggest that you change the frequency manually. If you still need to do it, it should change the transmitter frequency first, then change the receiver frequency to the same as the transmitter. It is better for you to reboot the transmitter and receiver. If you don't reboot, it also might be working.

15. Our engineers would like to understand how to control the settings of the modem. Do you have an API description? What they are trying to understand is how this data link can be integrated with our system so that the data link settings are controlled from our ground control station. Thank you.

Please check the PC AT commands at the link below . https://ivcan.com/uart-at-command-for-wireless-video-transmitter-and-receiver/

16. Does your transceiver data transmission rate depend on transmission frequency? If yes, then what is the data transmission rate at the lowest frequency? And what is the data transmission rate at the highest frequency?

1. In the same frequency band (such as 1.4G), the transmission rate we generally refer to (also called the air interface rate) mainly depends on the wireless bandwidth (such as 10MHz, 20MHz) and wireless modulation parameters (such as QPSK, QAM16, QAM64). 2. Among them, the wireless bandwidth is set by the user (such as the wireless page under the web page), but the wireless adjustment parameters are automatically and dynamically set by the system. For example, QAM64 is used for short distances, and QAM16/QPSK is used for long distances. This is different from one-way COFDM image transmission. 3. For example, with the same configuration of 20MHz bandwidth, the air interface rate is as high as 30Mbps at short distances, but only 3~4Mbps at extreme distances. As for what wireless adjustment parameters to use under what conditions, or the currently used wireless adjustment parameters, customers need to explore and operate by themselves. 4. What frequency band the customer chooses should not be based on the transmission rate of the high-frequency band, but also based on the legitimacy of the frequency band and whether the frequency band is "clean". Theoretically, the radio wave in the high-frequency band corresponds to a short cycle, so the transmission time is short and the transmission rate is fast, but the specific theoretical value, I can't answer you, the actual value, the customer can test it through the speed measurement software (the "measure" page of the TX900 webpage is integrated with IPERF speed measurement)

17. In the communication transmission kit, I need a joystick that works with your equipment.

Support. Our system is a transparent transmission system. That means that video or data you input, we will transfer. How to control the robot is up to you. We have clients who use a PTZ camera; the receiver also has a joystick to control the PTZ camera, zoom, move or rotate.

18. The maximum distances that can be achieved in LOS (line of sight) and NLOS (non-line of sight) transmission?

1. In the visible range, how far our wireless transmission system can support depends on the transmission distance we mentioned and the matching power amplifier you choose when purchasing. Can be selected from 7km, 15km, 30km, 50km, 80km, 100km, and 150km. 2. If the transmission module you choose can support up to 100 kilometers, but you do not choose our default 5-watt power amplifier, then this distance cannot be reached. 3. It is difficult to answer how many kilometers our transmission system can transmit with non-line-of-sight. Because non-line-of-sight transmission distance depends on what is the obstacle between the transmitter and receiver? If it is a metal-enclosed box indoors or on a mountain, the transmission distance cannot be determined. Wireless video transmission signals are just like radio or GPS signals; they must be able to obtain signals in the presence of diffraction. Preferably in an open area.

19. Can these transceivers be used for land-based applications such as remote surveillance of an area?

This is perfectly fine. We also have customers who use it for long-term video surveillance in harsh situations such as borders, grasslands, mines, and reservoirs.

20. How many cameras can be connected to a single transmitter for smooth transfer of video to the receiving station?

1. Connecting more cameras also ensures smooth video, depending on the pixels you choose for video and the transmission distance. 2. Our default transmission bandwidth is 20Mbps. If you connect four or five cameras, the pixels of each camera reach 1080p, and the transmission distance is more than 30 kilometers, the video will occasionally freeze. When this happens, you can adjust the video format to a lower video pixel, or reduce the number of cameras connected to the transmitter.

21. Maximum number of transmitters that can be connected to a single receiver?

1. The answer to this question is basically the same as the previous one because the bandwidth rate of our single set of links is 20Mbps. Connecting more transmitters, each transmitter will occupy the corresponding bandwidth. 2. The smoothness of the video depends on the pixel and transmission distance of each camera you choose. Below is a video of us testing three transmitters and one receiver in our office. The picture is quite smooth. https://youtu.be/XI0fdp_LctU

24. Provision of circuit diagram and the architectural details of the transceiver?

1. My engineers and I will provide detailed help and remote configuration according to your project needs. 2. For specific technical information, according to your needs, we will judge whether it can be opened for free. But we will definitely ensure that you can use the device normally.

25. Is it possible for 100 kms or more long distance above sea?

If used 10W power amplifier is used , it can reach 150~200km. (NLOS) Because of the curvature of the earth, which creates obstructions between the transmitter and receiver, and requires longer distances, it is necessary to ensure that the aircraft flies high enough or use an intermediate mission aircraft as a relay.

26. We are conducting a long-range automatic flight today. The drone lost connection with the first time at 11Km and it did not auto-reconnect for the whole flight. When the drone landed automatically, we restarted both modules manually then they connected again. Data port D1 is not used. D2 is SBUS, D3 is a TCP server.

According to our understanding, the hottest part should be the air unit(the access node), because the environment inside the aircraft is very narrow and closed. 1. The next time you find this kind of problem, you need to use the elimination method, because in general, the probability of unilateral problems is higher. For example, if we suspect that there is a problem with the access node at the aircraft unit. Then we only restart the access node at the aircraft unit. Do not restart the central node on the ground side to see if you can connect after restarting the access node on the aircraft side; there is a high probability that there is a problem with the access node on the aircraft side. 2. If there are conditions, for example, if the wired network port of the access node on the aircraft is exposed, then you can connect it to the computer, and log in to the wireless link web page (default 192.168. 1.12). On the debug page, send any AT command , and check whether the wireless transmission system can respond to AT commands normally. 3. There is a link core module in our transmitter and receiver. It has a log function. Before the flight, it will always record the operation status of the wireless link. When there is a problem, return to the ground, export the log information, and send the log file to MorningCore Help to analyze the reason there. How to get Log files to analyze and resolve TX900 link interruption faults.

27. If we use the transceivers, how about security? It is safe because we do not want to hack our data from hackers else

Our wireless video data transmission system supports AES 128 encryption. Banks also use this encryption algorithm. For more information, you can google search AES128.

28. Can you show me the pictures of the UAV radio link antenna, U-shaped mountain clamp and coaxial cables?

1. U-shaped mountain clamp for 120cm Receiver fiberglass FRP antenna 2. 150cm Coaxial cables for 29cm transmitter antenna 3. 150cm Coaxial cables for 120cm receiver antenna

29. Have you tested that your 5w OFDM VTX can reach about 55 km directly without a repeater? If yes, what is the altitude of the drone?? Is it really LOS without any obstacles?

It can go directly to 55km, and the height of the aircraft should be more than 300 meters. It is best to see through without occlusion, or there is basically no occlusion near the antenna.

30. What is the power consumption of the 5 W VTX in voltage and current?

The average power consumption of the video transmitter is less than 1.1A@24V, and the average power consumption of the video receiver is less than 0.8A@24V. Power supply range 24~28V.

31. Can it use lipo batteries? 6S battery?

Support lipo batteries. 6S battery: 3.76 x 6 = 22.2V , 4.26 x 6 = 25.2V, 22.2-25.2V, no problem.

32. Please tell us the HS code for your long-range two-way drone video transmitter and receiver system?

Some clients used the HS code 8517799000.

33. Does it support the MAVLink protocol? I can just attach the air unit to my flight controller, or do I need to set the Mavlink protocol communication in the transceiver? So it doesn't need any configuration for MAVLink?

Yes, our long-range drone wireless transmitter and receiver supports MAVLink protocol and flight control. Please check the operation at the link below . https://www.youtube.com/watch?v=KJ7JMZZNgcI https://www.youtube.com/watch?v=9uI_KZlKeOQ

34. When shipped, your TX900 sample is equipped with three data ports that are TTL.

We can customize them for you according to your demands.

35. Are they in pairs if I buy the device? I mean, for the receiver and transmitter. I'm planning to transmit a video stream wireless with an 18km .

Yes, for the transceiver, it is better to buy at least 2 pcs for one pair. You need to buy two, one for transmission and one for reception.

36. Hello, I am interested in a communication line for UAVs for video and telemetry transmission.

36.1. What was the maximum range you received with a transmitter power of 10 watts and at what altitude? ivcan: TX900-10W-150km, our clients can work well at 150~200km at the 1000-meter altitude. We tested the 110km from the mountaintop to the seaside. https://youtu.be/r1X4AU1togE 36.2. Communication via Ethernet supports all standard protocols, but are there any restrictions on UDP protocols? Or is the modem absolutely transparent from a network point of view? ivcan: Yes, our wireless link is like an invisible network cable; it supports almost all Ethernet protocols, TCP/ IP, etc. TX900 also supports absolutely transparent transmission. 36.3 Encryption is only possible with NPP 128, or is it possible with 256? ivcan: TX900 supports AES128 encryption. 36.4 Is the mesh function available for this modem? ivcan: TX900B has the IP mesh function. There are three versions of the transmission distance: 3km, 10km, and 50km. 36.5 Is it possible to quickly change the operating mode (during the flight) of the repeater between point to point? ivcan: Sorry, it can not change the operating model during the flight. You can change the role of the transceiver to the transmitter, receiver, or repeater on the ground.

37. How to add the IP camera video stream to my mission planner software?

I have an IP camera attached to the airborne transmitter . The video feed is being received on the receiver side. I can see the video feed in the IPCAM application. But now I want the video feed inside my mission planner software. Answer: Right-click on the HUD. There are several options to choose from. Please get help at the below link. https://ardupilot.org/planner/docs/mission-planner-flight-data.html

38. My requirement was only 1 km but with a high bandwidth (for data and video), at least 30Mbps - 50Mbps (24VDC power). also kindly send a datasheet of the unit.

Ok, one of our TX900 sub-models can support 30 to 50Mbps.

39. Is TX900 possible to connect a camera with RTSP protocol to the transmitter?

Yes, the TX900 supports a camera with the RTSP protocol. It also supports an IP Ethernet protocol camera, which you can use to submit camera PTZ (Pan/Tilt/Zoom).

40. What is included in the package of your TX900 whole set?

The TX900 default set includes one transmitter and one receiver, two 29cm transmitters, and two 120cm receiver antennae.

41. Why do you recommend using D2 / D3 as the data port?

D1 is the transparent serial port of the core wireless link modem. It is designed to ensure real-time performance but not the serial port data frame structure. Customers who use the SBus interface basically connect to drones; besides using the SBus interface, this type of demand also requires connecting to the flight control's telemetry interface TTL. At present, customers prefer to connect to the telemetry interface through a serial to network connection. D1 cannot be used for sbus or serial-to-network connections, so only the D3 serial port can be connected to the flight control's telemetry port. Therefore, for customers who need an Sbus interface, it is recommended that D2 be used for Sbus, D3 use TTL level, and D1 is up to the customer.

42. Why should I re-power the air unit when the air unit and ground reconnection?

We have a situation when the air and ground units are disconnected, they won't be connected automatically. If I power the air unit off and on, it reconnects. Please show us more details, and our engineer will offer you a specific solution.

43. Does your model TX900 support 4K 60fps?

Now it supports 4K 30fps, 3840*2160@30fps

45. Can you give me the answers to the question list below ?

1. Recovery after link loss in milliseconds 30ms 2. Receiver sensitivity 2.4G: 20MHz-99 10MHz-103 5MHz-104 3MHz -106 1.4G 10Mhz -103 5Mhz -104 3MHz -106 800M 10MHz-103 5MHz-104 3MHz-106 3. Operating current 2W: <1.1A@12V 5W: <1A@24V 4. Video channels 1-2 IP camera is better. Just like 2-5 computers share one net cable to transfer data, the more data the net speed will be slow. 5. Body type Heat dissipation aluminum 6. Compatible with Pixhawk? The serial port is in transparent transmission mode, so it can transparently transmit Pixhawk data. 7. TX ON-OFF capability? AT command mode, AT+CFUN=0 turns off Tx AT+CFUN=1 turns on Tx 8. Working temperature -40 degrees Celsius to 55 degrees Celsius

46. Can TX900 support one-way video, two-way audio, and dual-channel data?

I want to connect one DVR or NVR with 4 fixed HD cameras, one CVBS camera, and one PTZ camera, then send the video out signal from the DVR over the wireless signal and control the view layout and the PTZ camera using the serial signal sent over the wireless signal. Yes.

47. TTL port on the air and ground TX900 radios. The tracking antenna needs GPS telemetry to function. My questions are:

1) Does the TTL on the TX900 ground radio receive the telemetry from the air TTL connected to the autopilot? Answer: Yes 2) Does the Air TX900 support serial to Ethernet TCP/UDP functionality for direct connection by GCS software like Mission Planner? Answer: Yes Please check more settings at the video link below . https://youtu.be/_CNjksp7KaM https://youtu.be/9uI_KZlKeOQ https://youtu.be/KJ7JMZZNgcI

無人機遠距離視訊發射器終極常見問題解答指南

無人機遠距離視訊發射器

無人機遠端視訊發射器是指用於無人機和無人機的5-150公里遠端無線視訊發射器和接收器. 很難選擇和購買合適的型號.

你也有很多選擇, 而且買錯的成本非常高. 或許你也有很多疑問與疑惑. 這裡, 我列出了一些問題和答案供您參考. 請聯絡我們或者 WhatsApp我們如需任何進一步的協助, 我會盡力盡快準確地回答您的問題.

1. TX 和 RX 的價格必須是 2X, 正確的?

是, 用於兩路雙向無線視訊資料RC鏈路, 報價以一個單位為基礎. 如果您需要一台發射器和一台接收器, 那麼單價應該是2X.
也有顧客購買三套或三套以上; 中間的是中繼，可以進一步延長距離.
也有客戶擁有多個發射器和一個接收器或一個發射器和多個接收器. 數量根據您的需求而定, 所以成本就是單價X數量.

2. 預計要達到的海拔高度是多少 50 公里和 80 千米?

該無人機的飛行高度取決於其實際應用. 我們這裡所說的傳輸距離是根據可見光範圍來計算的. LOS (視線).

我們有一些客戶在大氣層中使用氣象氣球 (24-37千米 ) 監控設備的運作和效能.
使用無人機的客戶也越來越多, 只需保持無人機高於地面障礙物即可.

在我們的地面測試影片中, 為了測試傳輸距離 30 到 150 kilometers, 經常需要爬一座大約 1,000 米, 使視野開闊.

3. 我該選擇什麼功放? 2 瓦或 5 瓦特?

The power amplifier is a signal enlarger for longer transmission distances. We can offer you 0.3W, 1W¯¯, 2W¯¯, 5W and 10W.
Considering the 30km-50km transmission distance, it is better to choose 2 watts for 30~40km and 5 watts for 50~80km. 10 watts PA support 100~150km.

4. 所以每個單元都有雙向通訊功能, 正確的? 這意味著每個單元都可以充當中繼器或中繼功能, 正確的?

是, every unit of the two-way bidirectional model is a transceiver. You can put any unit to act as the relay or repeater between the transmitter and receiver.
wireless relay transmitter receiver system
two-way link transmitter receive repeater

5. 每個單元都可以傳輸視訊和遙測數據, 正確的?

是, each unit of TX900 has two RJ45 Ethernet ports for the IP camera. (also support extending more cameras by net switch), three data ports, and one bidirectional audio input-output.

6. 為什麼 5 瓦裝置有多個距離範圍? 我的意思是有 5 瓦特與 30 千米, 55 千米, 和 80 千米. 是軟體設定的原因還是什麼?

TX900 and Vcan1681 have software authorization on the transmission distance. Vcan1818 does not have this setting; 傳輸距離取決於功率放大器.

7. 的重量是多少 5 瓦特和 10 瓦特 ?

TX900: 5 瓦特: 142克和 10 瓦特 242 克

8. 什麼是延遲 (延遲) 的 5 瓦特 55 公里和80公里?

200-300女士視頻 (包括用於監控的攝影機)
30-60毫秒數據

9. 關於遙測數據, 是否相容MavLink協議, 因為我將使用 Pixhawk Ardupilot?

是, 支援

10. 使用之間的視頻質量怎麼樣 800 兆赫和 1.4 百萬赫? 哪個更好, 55 公里或 80 千米?

55公里和80公里時視訊品質相同.
工作頻率應根據您當地的頻率授權政策選擇.
如果您當地有 DVB-T / DVB-T2數位電視, 頻率範圍170~860MHz, 那麼推薦1.4GHz.
盡量避開本地已使用的頻率，減少干擾，避免畫質卡頓或馬賽克.

11. 軟體能否正確設定頻率?

是, 您可以在軟體Web UI或透過參數設定板工具設定頻率.
天線和PA擴大機工作在一定頻率範圍. 定制時它們的頻率範圍是固定的.
因此，當您改變頻率超出其頻率範圍時，您還應該更換天線和 PA.
例如, 當您告訴我們您同意工作頻率為1.4G時, 那麼天線和PA就可以在1.4G下正常運作, 即使您可以將發射器和接收器工作頻率變更為800Mhz, 您還需要更換800Mhz天線和PA.

12. 你有 1.2 百萬赫? 最好考慮 GPS 頻率.

TX900具有三個頻率範圍可供選擇: 800兆赫, 1.4百萬赫, 和2.4GHz.
Vcan1818工作頻率範圍可依您的專案需求預設.

13. 如果我買5瓦30公里, 我可以在未來升級到 55 公里或 80 公里執照?

當你買的時候, 功率放大器和最大傳輸範圍是固定的, 且無法透過軟體升級進行擴展, 除非你改變了收發模組和PA的硬體. 組裝複雜, 所以你最好買一件全新的.

14. 如果我們可以在不重新啟動無人機無線電的情況下更改以下參數，那就太好了: 頻率; 帶寬, 和功率放大器.

請注意我們的無線發射模組支援的頻段. 如1427.9~1447.9MHz (1.4G) 或806~826MHz (800兆赫), 或選購2401.5~2481.5MHz (2.4G).
必須選擇1.4G, 800兆赫, 購買時還是2.4G. (天線和PA將根據頻段定制).
在頻段內, 有很多頻點. 例如, 1.4G範圍是從 1427.90 至 1447.0MHz. 就像無線網路一樣, 模組會自動選擇目前訊號最好的頻點作為發射頻點, 所以不需要手動修改頻點，除非你想換到訊號較差的頻點.
所以我們工程師不建議您手動更改頻率. 如果你還需要這樣做, 它應該先改變發射器頻率, 然後將接收器頻率更改為與發射器相同.
最好重新啟動發射器和接收器. 如果不重新啟動, 它也可能有效.

15. 我們的工程師想了解如何控制數據機的設置. 有API說明嗎? 他們試圖了解的是如何將該數據鏈路與我們的系統集成，以便從我們的地面控制站控制數據鏈路設置. 謝謝.

請透過以下連結查看 PC AT 命令 .
https://ivcan.com/uart-at-command-for-wireless-video-transmitter-and-receiver/

16. 您的收發器資料傳輸速率是否取決於傳輸頻率? 如果是, 那麼最低頻率下的資料傳輸速率是多少? 最高頻率下的資料傳輸速率是多少?

1. 在同一頻段 (如1.4G), 我們一般所說的傳輸速率 (也稱為空中接口速率) 主要取決於無線頻寬 (例如10MHz, 20兆赫) 和無線調變參數 (例如QPSK, QAM16, QAM64).
2. 他們之中, 無線頻寬由使用者設定 (例如網頁下的無線頁面), 但無線調節參數由系統自動動態設定. 例如, QAM64 用於短距離, QAM16/QPSK 用於長距離. 這與單向COFDM影像傳輸不同.
3. 例如, 相同配置20MHz頻寬, 短距離空口速率高達30Mbps, 但在極遠距離只有3~4Mbps.
至於什麼條件下使用什麼無線調節參數, 或目前使用的無線調節參數, 需要客戶自行探索和操作.
4. 客戶選擇什麼頻段不應該以高頻段的傳輸速率為標準, 也要根據該頻段的合法性以及該頻段是否屬於 “乾淨的”. 理論上, 高頻段的無線電波對應短週期, 所以傳輸時間短，傳輸速率快, 但具體理論值, 我無法回答你, 實際值, 客戶可以透過測速軟體進行測試 (這 “措施” TX900網頁頁面整合了IPERF測速功能)

17. 通訊傳輸套件中, 我需要一個與你們的設備配合使用的操縱桿.

支持.
我們的系統是透明傳輸系統. 這意味著您輸入的影片或數據, 我們將轉移. 如何控制機器人由你決定.
我們有使用 PTZ 攝影機的客戶; 接收器還有一個操縱桿來控制 PTZ 攝影機, 飛漲, 移動或旋轉.

18. LOS 下可達到的最大距離 (視線) 和非視距 (非視線) 傳染?

1. 在可見光範圍內, 我們的無線傳輸系統能支援多遠取決於我們提到的傳輸距離以及您購買時選擇的配套功率放大器. 可以選擇7km, 15千米, 30千米, 50千米, 80千米, 100千米, 和150公里.

2. 如果您選擇的傳輸模組最多可以支援 100 kilometers, 但您沒有選擇我們預設的5瓦功放, 那麼這個距離就無法到達.

3. 很難回答我們的傳輸系統可以非視距傳輸多少公里.
因為非視距傳輸距離取決於發射器和接收器之間的障礙物是什麼?
如果是室內或山上的金屬封閉盒, 無法確定傳輸距離.
無線視訊傳輸訊號就像無線電或GPS訊號一樣; 他們必須能夠在存在衍射的情況下獲取訊號. 最好是在空曠的地方.

19. 這些收發器能否用於陸基應用，例如區域遠端監控?

這很好.
我們也有客戶在邊境等惡劣環境下使用它進行長期視訊監控, 草原, 地雷, 和水庫.

20. 單一發射器可以連接多少個攝影機，以便將視訊順利傳輸到接收站?

1. 連接更多攝影機也保證視訊流暢, 取決於您選擇的視訊像素和傳輸距離.

2. 我們預設的傳輸頻寬是20Mbps. 如果連接四個或五個攝影機, 每個相機像素達到1080p, 且傳輸距離大於 30 kilometers, 影片偶爾會凍結. 當這種情況發生時, 您可以將視訊格式調整為較低的視訊像素, 或減少連接到發射器的攝影機數量.

21. 單一接收器可連接的最大發射器數量?

1. 這個問題的答案和上一個基本上一樣，因為我們單組鏈路的頻寬速率是20Mbps. 連接更多發射器, 每個發射機都會佔用相應的頻寬.

2. 影片的流暢程度取決於您選擇的每個相機的像素和傳輸距離. 以下是我們在辦公室測試三個發射器和一個接收器的視頻. 畫面相當流暢.

22. 如果多個接收器放置在特定位置 (單一站點).那麼發送端如何區分需要連接哪個接收端?

1. 每個發射器和每個接收器都有其唯一的 IP 位址. Which transmitter and camera you access from the receiver depends on whether you know the IP address you set beforehand. This ensures that even if many sets of transmitters or receivers are in the same location, you can only access devices whose IP addresses you know.

2. At the same time our transmission and reception also support AES encryption and decryption. Even if other unauthorized users know your IP address, they cannot access or view the video of the transmitter and camera to ensure the privacy of wireless transmission.

23. 即時傳輸與錄影同時進行的NVR整合流程.

1. Most of our customers use the RTS player on their computers to watch or record the video content of the IP camera.

2. If you need to set up an NVR, our engineers can provide setup help according to your NVR-specific equipment.

24. 提供收發器的電路圖和架構細節?

1. 我和我的工程師將根據您的專案需求提供詳細的幫助和遠端配置.

2. 如需具體技術信息, 根據您的需求, 我們會判斷是否可以免費開通. 但我們一定會保證您可以正常使用設備.

25. 是否有可能 100 公里或更遠的海上距離?

如果使用10W功率放大器 , 可達150~200公里. (NLOS)

由於地球的曲率, 這會在發射器和接收器之間產生障礙, 並且需要更長的距離, 需要確保飛機飛得夠高或使用中間任務飛機作為中繼.

26. 我們今天正在進行遠程自動飛行. 飛行器在11公里處第一次失聯，全程沒有自動重連. 當無人機自動降落時, 我們手動重新啟動兩個模組然後它們再次連接. 數據連接埠D1未使用. D2 是 SBUS, D3是一個TCP伺服器.

據我們了解, 最熱的部分應該是空氣單元(接取節點), 因為飛機內部的環境非常狹窄且封閉.

1. 下次再發現這類問題時, 你需要使用排除法, 因為一般來說, 單方面出現問題的機率較高. 例如, 如果我們懷疑飛機單元的存取節點有問題. 然後我們只重啟飛行器單元的存取節點. 地面側中心節點不要重啟，飛機側接入節點重啟後看能否連接; 大概率是飛機側接取節點有問題.

2. 如果有條件的話, 例如, 如果飛機上接入節點的有線網路埠暴露, 然後就可以連接電腦了, 並登入無線連結網頁 (預設 192.168. 1.12). 在調試頁面, 發送任何 AT指令, 檢查無線傳輸系統是否能正常回應AT指令.

3. There is a link core module in our transmitter and receiver. It has a log function. Before the flight, it will always record the operation status of the wireless link. When there is a problem, return to the ground, export the log information, and send the log file to MorningCore Help to analyze the reason there. 如何取得Log檔案來分析和解決TX900鏈路中斷故障.

27. 如果我們使用收發器, 安全怎麼樣? 它是安全的，因為我們不想從其他駭客那裡竊取我們的數據

35. 如果我購買該設備，它們是成對的嗎? 我是說, 用於接收器和發射器. 我計劃以 18 公里的距離無線傳輸視訊串流 .

是, 對於收發器, 最好至少購買 2 一對.
你需要買兩個, 一根用於發送，一根用於接收.

36. 你好, 我對用於視訊和遙測傳輸的無人機通訊線感興趣.

36.1. 發射器功率為時接收到的最大範圍是多少 10 瓦數和海拔高度?

36.2. 透過乙太網路進行通訊支援所有標準協議, 但是UDP協定有什麼限制嗎? 或者從網路的角度來看調變解調器是絕對透明的?
伊夫坎: 是, 我們的無線連結就像一條看不見的網線; 它支援幾乎所有以太網協議, TCP/IP, 等等. TX900也支持絕對透傳.

36.3 加密只能透過 NPP 實現 128, 或有可能與 256?
伊夫坎: TX900支援AES128加密.

36.4 此數據機是否可使用網狀功能?
伊夫坎: TX900B具有IP mesh功能. 傳輸距離共有三個版本: 3千米, 10千米, 和50公里.

36.5 是否可以快速改變工作模式 (飛行期間) 點對點之間的中繼器?
伊夫坎: 對不起, 飛行過程中不能改變運作模式. 您可以將收發器的角色變更為發射器, 接收者, 或地面中繼器.

37. 如何將 IP 攝影機視訊串流新增至我的任務規劃軟體中?

D1為核心無線鏈路數據機的透明串口. 它的設計是為了保證即時性而不是串列資料幀結構.
rs232 convert sbus for drone wireless video transmitter and receiver
使用SBus介面的客戶基本上都是連接無人機; 除了使用SBus介面, 此類需求還需要連接飛控的遙測介面TTL. 現在, 客戶喜歡透過串列到網路連接來連接到遙測接口. D1 不能用於 sbus 或串列到網路連接, 所以飛控遙測口只能連接D3串口. 所以, 適合需要 Sbus 介面的客戶, 建議Sbus使用D2, D3使用TTL電平, D1 由客戶決定.

42. 天空端與地線重新連接後，為什麼要重新為天空端上電?

我們遇到了空中和地面單位斷開連接的情況, 它們不會自動連接. 如果我關閉然後再打開天空端電源, 它重新連接.
