1. Hä, the frequency range can be changed from 170Mhz (mäs xi hño from 220Mhz) ga 860 ar Mhz. So it can work well at 260Mhz band.
2. Ar frecuencia da modificar ar jar Nt'uti ar transmisor ne ar receptor. Ar causa, Amplificador nts'edi ne ar frecuencia ar antena tsa modificar xkagentho ar frecuencia. (You need to buy a power amplifier and antenna for the transmitter and receiver to meet your changed frequency).
3. In order to improve the sensitivity of transmitting and receiving, the frequency bandwidth is generally made very narrow (center frequency ±15MHz, so bandwidth should be 30Mhz). The power amplifier of the transmitter and the frequency of the antenna are specially customized according to the frequency you need.
4. It is best when you place an order, please tell me what kind of working frequency you need. Our engineers will modify the frequency of the transmitter and receiver, and also modify the PA and custom antenna according to this frequency range to ensure the best sensitivity and support the longest transmission distance.

1. If your area has a DVB-T or DVB-T2 digital television signal, ar TV frequency range is 170-860Mhz, it has including 800Mhz, so choose 1.4G is better.
2. 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. Komongu ar nt'uni, the 1.4G frequency effect on GPS is negligible.

The package size is 125 x 23 x 11 ar cm. Be̲xu bruto：3.72KG， Be̲xu ar volumen：7.5KG

Here is the full set picture.

Regarding frequency hopping, the engineer has some suggestions for you.

1. 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.
2. If 1410Mhz has jammed, then 1420Mhz also has jammed, as the frequency is too close.
3. When hopping frequency, the data or video transmission will be disconnected, and your video will be frozen.
4. Ar ora normal, it is better to choose hopping is NOT.
5. 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, pe̲ts'i 5 points to choose from for frequency hopping.

RSSI wireless link status data requires customers (such as flight controllers) to manually send AT commands to obtain it. It can be obtained in two ways:

1. Configure UART3 (data port 3rd) as an AT command serial port, and then send AT commands through UART3 (D3) to obtain. https://ivcan.com/change-d3-from-transparent-serial-port-to-at-command/
2. Update the firmware version 1.5.1 wa mäs xi ngu, so that there will be an additional TCP server inside for customers to access through TCP to send AT commands to obtain the wireless status.
3. The LED light is used to indicate the wireless connection status (ngu, if the wireless link is disconnected, the light will go out), and there is no dedicated external pin to notify the customer flight control.

Or see the UART AT command list nuwa.

or see https://ivcan.com/how-to-get-the-rssi-and-snr-on-the-drone-transmitter/

1. 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.
2. It won't send the failsafe command, but you can see the link status light from the signal indicator.
3. Here is the link status signal strength indicator means
   1. Not Bright: Indicates that the wireless link of the module is not connected
   2. Xí nthe̲ni: Indicates that the wireless link of the module has been connected, but the wireless signal strength is very weak
   3. Orange: Indicates that the wireless link of the module has been connected, and the wireless signal strength is medium
   4. Xí: Indicates that the wireless link of the module has been connected, and the wireless signal strength is very strong
4. 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.
5. You need to see the link status LED light, if it is Orange or Red, you should control the plane back in advance.
6. You also can get the RSSI at the below windows

Please check the upgrade firmware setps, download the latest upgrade firmware at the below link.

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, Hä, please buy 3rd nord as the reapter.
You just need to put the 3rd node in the middle and set the 3rd node be a 2D3U then ok.

How to set 3rd node be 2D3U?

Set with AT command:
at+cfun=0
at^dstc=0
at+cfun=1
Restart the link device after the operation

On the Web UI parameter mangagment page and debug section,

If you get result is 6602, then it is 15km Versión.

If you get result is 6603, then it is 30km Versión.

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, the shorter the transmission distance.
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 (Majwäni, 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.

1. 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
2. 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)
3. Slightly reduce the transmit power of the aircraft by the below AT commands: AT^DSSMTP="23" Reboot after setting

Ar nt'a̲ni: Are these settings maximum power of the module? (24 dBm)

Respuesta: 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.

Lead time: 10 days for small quantity order.

HS code: 8517629900

The difference between the air unit (transmisor) and ground unit (receptor) is two points:

One is the device type: Air unit (transmisor) is the Nodo nthogi and the ground unit (receptor) is the central node.

Two is the rate ratio of the downlink and up link. Over 30km, the best rate ratio is 4:1 o 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, ngu, 192.168.1.xxx.

1. Hä, there are three solutions to do that.
2. 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.
3. 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.
4. Or use two receivers: One receiver is for the mission plane (transmisor), and another receiver is for the repeater drone. The connection and operation are easier.
