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 estimate to achieve 50 km and 80 km?

The flying altitude of this drone depends on your 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 to a high mountain of about 1,000 meters, so that the field of vision is wide.

3. What power amplifier should I choose? 2 watts or 5 watts?

The power amplifier is a signal enlarger for the longer transmission distance. 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. So each unit has a 2-way communication function correct? That means each unit can function as a repeater or relay function correct?

Yes, every unit of the two-way bidirectional model is the transceiver. You can put any unit to as the relay or repeater between the transmitter and receiver.

5. Each unit can transmit Both Video and telemetry data correct?

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

6. Why does a 5-watt unit have several distance range? I mean there are 5 watts with 30 km, 55 km, and 80 km. Is it because of the software settings or what?

TX900 and Vcan1681 have software authorization on the transmission distance. Vcan1818 has no this setting, the transmission distance depends on the power amplifier.

7. What is the weight 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 one is better 55 km and 80 km?

The video quality is the same at 55km and 80km. The working frequency should choose according to 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 by the software correctly?

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 the some frequency range. Their frequency range is fixed when customized. So you should also change the antenna and PA when you modify 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 be working 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. Vcan1818 working frequency range can be preset according to your project need.

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 expend by software upgrade, except that you change the hardware of the transceiver module and PA. The assembly is complex, 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). At the frequency band, there are many frequency points. For Example, the 1.4G range is from 1427.90~1447.0Mhz. Like wifi, the module will automatically 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 that you reboot the transmitter and receiver. If you don't reboot, it also can 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 datalink can be integrated with our system so that datalink settings are controlled from our ground control station. Thank you.

Please check the PC AT commands at the below link. 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 in the lowest frequency? And what is the data transmission rate in 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 with which your equipment works.

Support. Our system is a transparent transmission system. That means that video or data you input, we will transfer them. How to control the robot, it is your parts. 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 distance 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 in the case of 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 pixels 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

22. If multiple receivers are placed in a particular location (single site).Then how the transmitter will distinguish that from which receiver it needs to be connected?

1. Every transmitter and every receiver has its unique IP address. 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. NVR integration procedure if live transmission and video recording are done simultaneously.

1. Most of our customers use the RTS player of the computer to watch or record the video content of the IP camera. 2. If you need to set up NVR, our engineers can provide setup assistance according to your NVR-specific equipment.

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

If used 10W power amplifier, 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 conduct a long-range automatic flight today. The drone lost connection 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 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: 3.7 6=22.2V, 4.2 6=25.2V, that is, 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 with 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 below link. https://www.youtube.com/watch?v=KJ7JMZZNgcI https://www.youtube.com/watch?v=9uI_KZlKeOQ

9. 关于遥测数据, 是否兼容MavLink协议, 因为我将使用 Pixhawk Ardupilot?

是, 支持

10. 使用之间的视频质量怎么样 800 兆赫和 1.4 千兆赫? 哪一个更好 55 公里和 80 千米?

55公里和80公里时视频质量相同.
工作频率根据您当地的频率授权政策选择.
如果您当地有 DVB-T / DVB-T2数字电视, 频率范围为170~860Mhz, 那么推荐1.4Ghz.
尽量避开本地已使用的频率，减少干扰，避免画质卡顿或马赛克.

11. 软件能否正确设置频率?

是, 您可以在软件Web UI或通过参数配置板工具设置频率.
天线和PA功放工作在一定频率范围. 定制时它们的频率范围是固定的.
所以当你修改的频率超出了它们的频率范围时，你也应该更换天线和PA.
例如, 当您告诉我们您同意工作频率为1.4G时, 那么天线和 PA 将在 1.4G 下正常工作, 即使您可以将发射器和接收器工作频率更改为800Mhz, 您还需要更换800Mhz天线和PA.

12. 你有 1.2 吉赫兹? 这个更好, 考虑 GPS 频率.

TX900具有三个频率范围可供选择, 800兆赫, 1.4吉赫兹, 和2.4GHz.
Vcan1818工作频率范围可根据您的项目需要预设.

13. 如果我买5瓦30公里, 我可以在未来升级到 55 公里或 80 公里执照?

当你买它的时候, 功率放大器和最大传输范围是固定的, 并且不能通过软件升级来消耗, 除非你改变了收发模块和PA的硬件. 组装复杂, 你最好买一件全新的.

14. 如果我们可以在不重新启动无人机无线电的情况下更改以下参数，那就太好了: 频率; 带宽, 和功率放大器.

请注意我们的无线发射模块支持的频段. 如1427.9~1447.9MHz (1.4G) 或 806~826MHz (800兆赫), 或可选2401.5~2481.5MHz (2.4G).
必须选择1.4G, 800兆赫, 购买时还是2.4G. (天线和PA将根据频段定制).
在频段, 有很多频点. 例如, 1.4G范围为1427.90~1447.0Mhz. 喜欢无线网络, 模块会自动选择当前信号最好的频点作为发射频点, 所以不需要手动修改频点，除非你想换到信号较差的频点.
所以我们工程师不建议您手动更改频率. 如果你还需要这样做, 它应该首先改变发射器频率, 然后将接收器频率更改为与发射器相同.
最好重新启动发射器和接收器. 如果不重新启动, 它也可以工作.

15. 我们的工程师想了解如何控制调制解调器的设置. 有API说明吗? 他们试图了解的是如何将该数据链与我们的系统集成，以便从我们的地面控制站控制数据链设置. 谢谢.

请通过以下链接查看 PC AT 命令.
https://ivcan.com/uart-at-command-for-wireless-video-transmitter-and-receiver/

16. 您的收发器数据传输速率是否取决于传输频率? 如是, 那么最低频率下的数据传输速率是多少? 最高频率下的数据传输速率是多少?

1. 在同一频段 (比如1.4G), 我们一般所说的传输速率 (也称为空中接口速率) 主要取决于无线带宽 (比如10MHz, 20兆赫) 和无线调制参数 (例如QPSK, QAM16, QAM64).
2. 他们之中, 无线带宽由用户设置 (比如网页下的无线页面), 但无线调节参数由系统自动动态设置. 例如, QAM64 用于短距离, QAM16/QPSK 用于长距离. 这与单向cofdm图像传输不同.
3. 例如, 相同配置20MHz带宽, 短距离空口速率高达30Mbps, 但在极远距离只有3~4Mbps.
至于什么条件下使用什么无线调节参数, 或当前使用的无线调节参数, 需要客户自行探索和操作.
4. 客户选择什么频段不应该以高频段的传输速率为标准, 还要根据该频段的合法性以及该频段是否属于 “干净的”. 理论上, 高频段的无线电波对应短周期, 所以传输时间短，传输速率快, 但具体理论值, 我无法回答你, 实际值, 客户可以通过测速软件进行测试 (该 “措施” TX900网页页面集成了IPERF测速功能)

17. 通讯传输套件中, 我需要一个与您的设备配合使用的操纵杆.

支持.
我们的系统是透明传输系统. 这意味着您输入的视频或数据, 我们将转移它们. 如何控制机器人, 这是你的部分.
我们有使用 PTZ 摄像机的客户, 接收器还有一个操纵杆来控制 PTZ 摄像头, 飞涨, 移动或旋转.

18. LOS 下可达到的最大距离 (视线) 和非视距 (的非视距) 传送?

1. 在可见光范围内, 我们的无线传输系统能支持多远取决于我们提到的传输距离以及您购买时选择的配套功率放大器. 可以选择7公里 15公里, 30千米, 50公里 80 公里, 100千米, 和 150 公里.

2. 如果您选择的传输模块最多可以支持 100 公里, 但您没有选择我们默认的5瓦功放, 那么这个距离就无法到达.

3. 很难回答我们的传输系统在非视距情况下可以传输多少公里.
因为非视距传输距离取决于发射器和接收器之间的障碍物是什么?
如果是室内或山上的金属封闭盒, 无法确定传输距离.
无线视频传输信号就像无线电或GPS信号一样, 他们必须能够在存在衍射的情况下获取信号. 最好是在空旷的地方.

19. 这些收发器能否用于陆基应用，例如某个区域的远程监控?

这很好,
我们也有客户在边境等恶劣环境下使用它进行长期视频监控, 草原, 地雷, 和水库.

20. 单个发射器可以连接多少个摄像机，以便将视频顺利传输到接收站?

1. 连接更多摄像头也保证视频流畅, 取决于您选择的视频像素和传输距离.

2. 我们默认的传输带宽是20Mbps. 如果连接四个或五个摄像头, 每个摄像头像素达到1080p, 且传输距离大于 30 公里, 视频偶尔会冻结. 当这个情况发生时, 您可以将视频格式调整为较低的视频像素, 或减少连接到发射器的摄像机数量.

21. 单个接收器可连接的最大发射器数量?

1. 这个问题的答案和上一个基本一样，因为我们单组链路的带宽速率是20Mbps. 连接更多发射器, 每个发射机都会占用相应的带宽.

2. 视频的流畅程度取决于您选择的每个摄像头的像素和传输距离. 以下是我们在办公室测试三个发射器和一个接收器的视频. 画面相当流畅.
HTTPS://youtu.be/XI0fdp_LctU

22. 如果多个接收器放置在特定位置 (单一站点).那么发射器如何区分需要连接哪个接收器?

1. 每个发射器和每个接收器都有其唯一的 IP 地址. 从接收器访问哪个发射器和摄像头取决于您是否知道事先设置的IP地址. 这确保了, 即使多组发射器或接收器位于同一位置, 您只能访问您知道 IP 地址的设备.

2. 同时我们的发送和接收也支持AES加密和解密. 即使其他未经授权的用户知道您的 IP 地址, 他们无法访问或查看发射器和摄像头的视频，以确保无线传输的私密性.

23. 实时传输和录像同时进行的NVR集成流程.

1. 我们大多数客户使用电脑的RTS播放器来观看或录制网络摄像机的视频内容.

2. 如果您需要设置NVR, 我们的工程师可以根据您的 NVR 特定设备提供设置帮助.

24. 提供电路图和收发器的架构细节?

1. 我和我的工程师将根据您的项目需求提供详细的帮助和远程配置.

2. 如需具体技术信息, 根据您的需求, 我们会判断是否可以免费开通. 但我们一定会保证您可以正常使用设备.

25. 是否有可能 100 公里或更远的距离见上面?

如果使用10W功放, 可达150~200公里. (NLOS)

由于地球的曲率, 这会在发射器和接收器之间产生障碍, 并且需要更长的距离, 需要保证飞机飞得足够高或者使用中间任务飞机作为中继.

26. 我们今天进行远程自动飞行. 飞行器在11公里处第一次失联，全程没有自动重连. 当无人机自动降落时, 我们手动重新启动两个模块然后它们再次连接. 数据端口 D1 未使用. D2 是 SBUS, D3是TCP服务器

据我们了解, 最热的部分应该是空气单元(接入节点), 因为飞机内部的环境非常狭窄和封闭.

1. 下次再发现此类问题时, 你需要使用排除法, 因为一般来说, 单方面出现问题的概率较高. 例如, 如果我们怀疑飞机单元的接入节点有问题. 那么我们只重启飞行器单元的接入节点. 请勿重启地面侧中心节点，重启飞行器侧接入节点后看能否连接, 大概率是飞机侧接入节点有问题.

2. 如果有条件的话, 例如, 如果飞机上接入节点的有线网口暴露, 然后就可以连接到电脑了, 并登录无线链接网页 (默认 192.168. 1.12). 在调试页面, 发送任何指令, 检查无线传输系统是否能正常响应AT指令.

3. 我们的发射器和接收器中有一个链路核心模块. 它有日志功能. 航班起飞前, 会时刻记录无线链路的运行状态. 当出现问题时, 返回地面, 导出日志信息, 并将日志文件发送到MorningCore Help来分析原因. 如何获取Log文件来分析和解决TX900链路中断故障.

27. 如果我们使用收发器，那么安全性如何，因为我们不想从其他黑客那里窃取我们的数据

我们的无线视频数据传输系统支持AES 128 加密, 银行也使用这种加密算法. 了解更多信息, 你可以谷歌搜索 aes128.

28. 你能给我看一下无人机无线电链路天线 U 形山夹和同轴电缆的图片吗?

1. 120cm接收器玻璃钢天线U型山夹
U-shaped Mounting clamp
2. 150cm 同轴电缆，用于 29cm 发射器天线

29. 你测试过你的5w OFDM VTX可以达到大约 55 无需中继直接公里? 如是, 无人机的飞行高度是多少?? 真的是LOS无障碍吗?

可直达55公里, 且飞行器高度应大于 300 米. 最好能看透, 无遮挡, 或者天线附近基本没有遮挡.

30. 耗电量是多少 5 w VTX 电压和电流?

视频传输器平均功耗小于1.1A@24V, 视频接收器平均功耗小于0.8A@24V. 供电范围24~28V.

31. 可以使用锂电池吗? 6S电池?

支持锂电池.
6S电池: 3.76=22.2V, 4.26=25.2V, 那是, 22.2～25.2V, 没问题.

32. 请告诉我们您的远程双向无人机视频发射器和接收器系统的 HS 代码?

部分客户使用HS编码 8517799000.

33. 是否支持Mavlink协议? 我只需将空中装置与飞行控制器连接即可, 或者我需要在收发器中设置Mavlink协议通信? 所以Mavlink不需要任何配置?

是, 我们的远程无人机无线发射器和接收器支持Mavlink协议和飞行控制. 请通过以下链接查看操作情况.

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

We can customize them for you according to your demand.

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 distance.

是, for the transceiver, it is better to buy at least 2 一对 pcs.
You need to buy two, one for transmission and one for reception.

36. 你好, 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?
伊坎: TX900-10W-150km, Our clients can work well at 150~200km at the 1000-meter altitude. We tested 110km from the mountain top to the seaside. https://youtu.be/r1X4AU1togE

36.2. Communication via Ethernet supports all standard protocols and are there any restrictions on UDP protocols? Or the modem is absolutely transparent from a network point of view?
伊坎: 是, our wireless link is like an invisible net cable, it supports almost ethernet protocols, TCP/ IP, 等等. TX900 also supports absolutely transparent transmission.

36.3 Encryption is only possible with NPP 128, or is it possible with 256?
伊坎: TX900 support AES128 encryption.

36.4 Is the mesh function available for this modem?
伊坎: TX900B has the IP mesh function. There are three versions of the transmission distance: 3千米, 10千米, 和 50 公里.

36.5 是否可以快速改变工作模式 (飞行期间) 点对点之间的中继器?
伊坎: 抱歉, it can not change the operating model during the flight. 您可以将收发器的角色更改为发射器, 接收器, 或地面中继器.

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

I have an IP camera attached to the transmitter airborne. 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.

回答: Right-click on the HUD. There are several options to choose from.

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

好的, 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?

是, TX900 supports a camera with RTSP protocol.
It also supports an IP ethernet protocol camera, which you can 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.

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, they reconnect.
Please show us more details and our engineer will offer you the specific solution.

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

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