Futaba FUSBE1 S.BUS Signal Encoder — 10-Channel PWM Converter  [FUSBE1]

The Futaba FUSBE1 is a dedicated S.BUS signal encoder that converts up to ten separate analog PWM servo outputs into one S.BUS data line, intended for use with Futaba S.BUS compatible receivers and setups.

Serving as a wire-reduction and signal-aggregation accessory, the encoder enables you to gather multiple PWM-controlled servos onto a single S.BUS bus, lowering the number of occupied receiver ports and simplifying internal routing in detailed scale builds and complex control assemblies. It functionally translates standard PWM channel outputs into the S.BUS digital protocol while keeping each channel distinct.

Fitting the unit is typically simple: fasten it in a safe location, plug each PWM lead from servos or modules into the encoder's inputs, then connect the single S.BUS output to the receiver. During configuration, consult transmitter and receiver guidance for S.BUS channel layout and ensure any receiver S.BUS mode is active so channels register correctly.

The encoder passes channel outputs transparently and is not a mixer. Continue to perform mixing, subtrim and endpoint adjustments on the transmitter or in dedicated controllers while the encoder handles the signal routing onto S.BUS.
