Futaba FUSBE1 10-Channel Analog PWM to S.BUS Signal Encoder  [FUSBE1]

The Futaba FUSBE1 is an accessory-grade S.BUS signal encoder designed to convert up to 10 separate analog PWM servo outputs into a single S.BUS data line for use with Futaba S.BUS-compatible receivers and systems.

As a wire-reduction and signal-aggregation tool, the encoder lets you consolidate multiple PWM-controlled servos onto one S.BUS bus, reducing receiver port usage and simplifying wiring inside scale models and complex assemblies. It operates as a translator between conventional PWM servo channels and the S.BUS digital bus protocol, preserving independent channel control while centralizing the signal path.

Installation is straightforward in most setups that accept external signal encoders: mount the unit in a secure location, connect each PWM output from servos or control modules to the encoder inputs, and route the single S.BUS output to the S.BUS input on the receiver. During setup, check the radio and receiver documentation for S.BUS channel mapping and enable any required S.BUS mode to ensure the encoder's channels are recognized correctly.

In tuning and system configuration, the encoder functions as a neutral passthrough for channel assignments rather than as a mixer or controller. Use your transmitter's mixing and subtrim features to refine servo endpoints and centering while the encoder routes those signals onto the S.BUS network.
