Instructions for placing an order

Serial port is TTL or RS232

What baud rate needs to be set

Receiver Antenna

At the default package, we will send you 2 pcs omnidirectional antenna for the transmitter and receiver. If your transmission range is over 100km, it is better to change a directional antenna to the ground receiver and try to install it as high as possible.

 

1. Does your wireless data transmission support Pixhawk autopilot? Can it send data/video? What is the frequency?

1. Support Pixhawk autopilot.
2. Can send rand receiver the data, but no video, if need data+video, please check TX900
3. The working frequency is from 902Mhz to 928Mhz.

2. Does the antenna is omnidirectional or directional?

1. A small antenna in the air unit is omnidirectional, including.
2. A big antenna in the ground unit, it is better to use a directional antenna, not including.

3. If I buy 3 units, can we control 2 drones at the same time, switching between them?

1. Our wireless data transmission supports multi-point-to-point networking, and one ground unit can control multiple drones.

4. What should I do if I lost one unit? (the transmitter with the drone has lost)

1. You should buy a new one and pair them.

5. Are they full-duplex and RS232 port?

1. Yes, it is full-duplex.
2. We can customize the data port to RS232 if you need.

6. If I change the Baud rate from 57600 to 115200, will this affect distance or data?

1. It doesn't matter if the serial port baud rate is changed to 115200, but the corresponding serial port baud rate of the flight controller must also be changed to 115200.
2. Of course, you can also change the serial port baud rate to 57600. The biggest impact is that the flight control may increase the amount of data as the serial port baud rate increases. This is the only impact.

7. What is the power supply and power pin define?

1. 10-watts Power Amplifier model needs 24V power supply

8: I would like to know if it is possible, to have RSSI signal strength when receiving data.

1. This model vcan1878 cannot carry signal strength behind the data；
2. Signal strength can be read through the control serial port；
3. When the data serial port is used for data transmission, the control serial port can read the signal strength；
4. If the signal strength is read through the AT command, the data transmission will stop；
5. Of course, you can also read the signal strength yourself through the API protocol.
6. This is equivalent to the customer only needing to send a protocol data packet to query the energy to the control serial port, and the module set will output the energy value, so there is no need to use the UI parameter software.

9: For Mesh mode I would like to make sure that slave-to-slave can be communicated directly.

1. We have a centralized mesh mode, which is point-to-multipoint, and slaves can communicate with each other.
2. However, the transmission between slaves is sent by broadcast, and the centralized mesh mode has no retransmission mechanism, so the performance is worse than point-to-point and point-to-multipoint.
