The Frsky ASS70/ASS100 ADV air speed sensor user manual provides installation steps, configuration, specifications, and usage guidelines.
The ASS70 and ASS100 ADV air speed sensors are designed for systems with Frsky Smart Port interfaces and measure airflow speed during flight. The manual introduces the product, its purpose, and the required safety precautions.
It covers connection of the pitot tube, recommended placement on the aircraft, wiring to the Smart Port, ID configuration via Free Link ETHOS, LED status indicators, and detailed electrical and mechanical specifications for both models. This manual is written in Chinese.
