1. Disclaimer
Thank you for purchasing the V31 video&data&RC link. Please use it following the local
radio control regulations and read this statement carefully before using it. Once used, it
shall be deemed to endorse and accept all contents of this statement. Please strictly follow
this instruction to install and use the product. The supplier will not bear any legal liability
for any result or loss caused by improper use, installation, final assembly or modification of
the product.
2. Product Precautions
1. V31 airborne unit and ground unit need external power supply input DC7.4-30V (lithium
battery 2s-6s), please follow the specification to power the radio.
2. Be sure to install the antenna before powering up to avoid damaging the circuit.
3. Ensure that the antennas are free from obstruction and bending, and keep them as far
away from large metal objects as possible to avoid blocking communication for the above
reasons.
4. Please do not disassemble or modify the V31. If you encounter any problems that cannot
be solved during installation or use, please contact Chinowing Technology Co., Ltd.
5. Make installation with proper distance between electronic devices to minimize
electromagnetic interference.
6. Before use, make sure that all wiring is securely fastened and that all components are
working properly.
7. Please check the surrounding environment to ensure that there is no interference from
other devices in the same frequency band before use, otherwise, the data transmission of
V31 may be seriously affected
8. If you encounter any problem during the installation or use, please contact us or visit our
website at www.chinowing.com for technical support.

3. Product Introduction and Parameters
V31 Digital video and data transmission module is the wireless digital data link based on
LTE wireless communication, adopting OFDM and MIMO technology. It can transmit
telemetry data and real-time video streaming and has 2*SBUS ports, able to provide control
of the drone and the payload.
There are 2 frequencies for choice, 800MHz and 1.4GHz.
High integration greatly reduces the power consumption and the dimension of the product,
which can satisfy the requirement of UAV, UGV, etc.

6. Product Instruction
Power on the airborne unit and ground unit. After the successful connection of the two
modules(signal indicator is constant, this process takes about the 30s), the device can work
normally, and all parameters have been configured well. If you want to modify the baud rate
of the serial port and the IP address of the network port, please refer to the corresponding
steps.
Note! The products are factory configured and ready for use. Default configuration

6.1 S-BUS port operation
1. Connect the SBUS port of V31 ground unit with the SBUS signal source of RC receiver. The
SBUS indicator will flash quickly when there is data input.
2. Connect the SBUS port of V31 airborne unit to the device you need to control.

6.3 Abnormal bottom noise
When S1 red light is flashing, the main antenna has poor bottom noise; when S2 red light is
flashing, the secondary antenna has poor bottom noise.
Please check whether there is any abnormality of the corresponding antenna, feeder line,
connection and installation position when there is bottom noise fault phenomenon,
otherwise it will affect the transmission distance.
The bottom noise prompt function is suitable for the pre-flight check, like indoor installation
and debugging. It works in the range of 200 meters between Tx and Rx after V31 link
successful connection. This function will be closed automatically after the range is more than
200 meters.
For the bottom noise test, pls try to avoid going through walls, etc, in case of inaccurate
results. Pls, do it in the LOS condition.
6.4 Check the frequency
V31 has 2 frequencies for choice, 800MHz, 1.4GHz.
For frequency checking, pls press the SET button <3 seconds when power on, S3 indicator
light Red indicates 800MHz; S2, S3 indicator lights Red indicates 1.4GHz.
