Radiolink is a high technology manufacturing company dedicated to researching, manufacturing and marketing of RC model radio transmitters. We are committed to providing customers with a high reliability and high performance product solution, as well as providing technical support and friendly after-sales service.

How to connect:
1.Require your PIXHAWK is version 3.5 or later version when you will use automatic obstacle avoidance function.
2.Use the 6pin wire connect the Ultrasonic Sensor SU04 insert to the TELEM1 or TELEM2 port of PIX.

Please Note:
1.Automatic obstacle avoidance function asks the firmware of PIXHAWK is version 3.5 or later version.
2.The flight controller cannot identify the detection distance when the sensor is far from the obstacle more than 450cm, it will altitude hold by barometer.
3.PIXHAWK have to powered by LiPo battery, it cannot power by USB when you use this utrasonic sensor SU04.
4.When you ready for the first flight, please make your drone at a lower speed to keep the safe flight.
5.please reconnect the PIXHAWK and reopen the MP after all the parameters setup as all the above steps.
