This is the instruction manual for FrSky Redundancy Bus-10
The FrSky Redundancy Bus-10 transmits real-time values for voltage, servo status (good or overloaded), and receiver status (detected channels and signal output period) to FrSky radio systems.
To solve SBUS signal polarity compatibility issues, the manual provides steps to reverse the supported SBUS signal polarity. This involves connecting specific signal pins (e.g., ch3&ch4) with a jumper, powering the unit, and then removing the jumper to reset the polarity. This manual is written in Chinese.
The system transmits actual voltages of both inputs, servo status (good or overloaded), and receiver status including the number of detected channels and output period of signal.
Connect the signal pins of ch3&ch4 by a jumper, connect the power supply to BATT 1 or BATT 2, then remove the jumper and disconnect the power supply.
