# RC In/SBus Wiring

To Enable SBus input, use a male>male jumper to connect the top pins together, and then connect RC SBus to "Sbus" Pin. UART 5 is reserved for SBus.

To use TBS Crossfire style RC Link (using a Normal UART) ensure SBus jumper is NOT fitted and use the 5v, Gnd, R5, T5 pins.&#x20;
