- If your area has a DVB-T or DVB-T2 digital television signal, da TV frequency range is 170-860Mhz, it has including 800Mhz, so choose 1.4G is better.
- Because the GPS antenna receives the GPS signal and the GPS direction on the drone is up, our transmitter antenna is pointing down to send the signal to the ground. Saboda, the 1.4G frequency effect on GPS is negligible.
The package size is 125 x 23 x 11cm. Cikakken nauyi:3.72KG, Volume Weight:7.5KG
Here is the full set picture.
Regarding frequency hopping, the engineer has some suggestions for you.
- As the system frequency range is 20Mb, if your bandwidth is chosen 20Mb, then it can not hop (only one point). If the bandwidth is chosen 10Mb, then you have two points to hop, if the bandwidth is chosen 5Mb, then you have 4 points to hop.
- If 1410Mhz has jammed, then 1420Mhz also has jammed, as the frequency is too close.
- When hopping frequency, the data or video transmission will be disconnected, and your video will be frozen.
- A lokacin al'ada, it is better to choose hopping is NOT.
- If your transmission distance is less than 15~22km, then we have another option to choose from, the frequency has 110Mb, and even if you choose 20Mb bandwidth, yana da 5 points to choose from for frequency hopping.
If you need to support S.bus, then please tell us before shippment, and we will modify our RS232 to TTL.
Our TX900 has three RS232 ports. If you need it to support S.bus, just need plus one small converter from S.BUS to RS232 is ok. ( Mini SBUS Conversion Module Uart to Sbus, Sbus to Uart ).
Please tell us if you need sbus port before delivery. Our engineer will modify the D2 port from RS232 to Sbus.

- The serial port of our wireless video transmission is transparent, and no data is actively sent to the flight controller. This is controlled by the ground station.
- It won't send the failsafe command, but you can see the link status light from the signal indicator.
- Here is the link status signal strength indicator means
- Not Bright: Indicates that the wireless link of the module is not connected
- Red: Indicates that the wireless link of the module has been connected, but the wireless signal strength is very weak
- Lemu: Indicates that the wireless link of the module has been connected, and the wireless signal strength is medium
- Green: Indicates that the wireless link of the module has been connected, and the wireless signal strength is very strong
- We understand that you hope to have this function, If aircraft loses signal during flight it will not return to home because flight controller will not understand that rc link is lost.
- You need to see the link status LED light, if it is Orange or Red, you should control the plane back in advance.
- You also can get the RSSI at the below windows

At the normal usage, one node as the transmitter, another node as the receiver. If you need to support long range or over a mountain top, like the below picture, a, please buy 3rd nord as the reapter.

4K video is supported.
4K video stream generally has more than 8Mbps, and 1080P video generally has more than 2M, so the distance of our wireless video transmission when transmitting 4K video will be shorter than that of 1080P.
In one word, the higher the definition of the video, guntu nisan watsawa.
The video compression is smaller, and the transmission distance is supported farther.
In the process of video transmission, if there is data loss, the picture will appear mosaic or stagnation, freeze and other phenomena.
There will be a limited number of retransmissions at the wireless link level (i mana, data errors will also occur if the situation is not good). The upper-layer application on the end will not be aware of it, nor will it ask the sender to retransmit.
If the signal of the wireless link is not good at a certain point after the distance is extended, and there are always bit errors, it is impossible to design it to be retransmitted all the time, so that the end user experience will be very poor.
The wireless link layer has a limited retransmission mechanism. We have tested the tcp protocol for transmission at the video transmission layer (trying to retransmit on the upper layer through the tcp protocol), but the test found that there is no obvious improvement, and it will also lead to uncontrollable delays.
- The heat generated by the aircraft side is much larger than that of the ground side. If the fan is running, check whether the air inlet and outlet of the lower fan (the positions of the heat sinks at both ends) are blocked
- Try changing the power supply of the air unit transmitter from 24V to 12~18V (the transmit power will be reduced to about 35~36DB)
- Slightly reduce the transmit power of the aircraft by the below AT commands: AT^DSSMTP="23" Reboot after setting
tambaya: Are these settings maximum power of the module? (24 dBm)
Amsa: 24dBm is the maximum output power of the link Module, and the gain of the PA (about 14dBm) needs to be added. The actual transmission power after the 24V power supply PA output is about 38dBm.

The difference between the air unit (watsawa) and ground unit (mai karɓar) is two points:
One is the device type: Air unit (watsawa) is the kumburin shiga and the ground unit (mai karɓar) is the central node.
Two is the rate ratio of the downlink and up link. Over 30km, the best rate ratio is 4:1 ko 3:2.
If you don't want to connect the receiver ethernet cable directly to the computer. Then it is not easy to access the receiver at your local network.
Here is two solutions for you.
1. Add the IP address of the 192.168.1.x network segment on the PC side (the PC can be configured with multiple network segment IP addresses)
2. Modify the IP of the wireless video data receiver from 192.168.1.12 to the address of the 10.220.20.x network segment to meet your local network.
For further questions and solutions, please talk with your local area network workmate or engineer, our receiver is like a computer with IP address, it should keep the network segment IP address at the same, misali, 192.168.1.xxx.
- a, there are three solutions to do that.
- TX900 has three data ports. Distinguish through different transparent serial ports, such as D2 to control relay aircraft and D3 to control mission aircraft. The disadvantage is that the TX900 receiver needs to be connected to two serial ports to send instructions separately.
- Use the same transparent serial port to send data in bulk, and then add layer protocols (such as header information) to the data to distinguish which aircraft should receive and process the data. The disadvantage is that the processing of sending and receiving data is complicated.
- Or use two receivers: One receiver is for the mission plane (watsawa), and another receiver is for the repeater drone. The connection and operation are easier.

Optional TX900B for some clients need frequency hopping function.
- TX900B-2W supports the frequency range is 1420~1530MHz, and there is 110Mb bandwidth to use. (800Mhz frequency range does not support this 110Mb bandwidth)
- The customer can set the working bandwidth as 1.4M/3M/5M/10M/20MHz (However 1.4M/3MHz may not be suited for video transmitting). Then TX900B-2W can work in FHSS mode (Mitar-hopping yada bakan) and the central working frequency will be automatically selected by the system and may do frequency hopping (between 1420~1530MHz) during its working.
- Customers can also plan to use the frequency channels in the whole 1420~1530MHz and set the device to work in the fixed frequency channels too.
- TX900B-2W supports the longest distance at 22km.
- Except for the frequency range supported and the longest distance, the physical appearance, dubawa, UI, aiki, da sauransu, the TX900B-2W is the same as the existing TX900B-15km-2W.
- TX900B-2W only supports a frequency range is 1420~1530MHz, it does not support 800MHz and 2.4GHz frequency ranges.
- There are two versions, TX900B-2W-15km, and TX900B-2W-22km.
- As the TX900B-2W frequency range is 110Mb, so if you configure the working bandwidth as 10Mb, then you will get 11 points to hopping.
- TX900B supports 110Mb bandwidth for frequency hopping and only has three transmission ranges optional, 22km, 55km, kuma 150km.
