If you have the Futaba Rx and Tx bound together and the SBUS converter is connected correctly to the Rx and M4 board than all you need to do is set the M4 board to use the inverted SBUS signal.
Christof gave you a link to the information you need.
"RC1: Primary radio type on RC port 1.
For AQ6 this is the main external receiver port (white 3-pin connector) for Spektrum, SBus, SUMD, and MLink), or Motor Port 14 for PPM input.
For AQ M4, this is the built-in radio port (Spektrum or Deltang).
RC2: Radio type on RC port 2.
For AQ6 this can be Motor Port 14, for PPM input only.
For AQ M4, this is the external radio connection for Spektrum, SBus, SUMD, MLink, or PPM."
Changing the RC2 setting to "SBus" using the QGC while it's connected to your M4 board should give you success.
