The DJI D-BUS ADAPTER module can provide eight-way input or output for
the A2 Multirotor Flight Controller. A traditional receiver can be used
through this module, or can be used to extend the output ports. Please
refer to the A2 user manual D-BUS ADAPTER section for more specific
details of functionality. When using a traditional D-BUS receiver with
the A2, the DJI D-BUS Adapter is required.
D-BUS Adapter Setup:
-
Put the switch to the “I” stop, and power on the system. The LED
should be on red; otherwise keep the switch at the “I” stop and then
power cycle the system.
-
At the “I” stop, the D-BUS Adapter is converting the PWM signal from traditional receiver to S-BUS signal.
