Futaba FUSBS-01A Barometric Vario Module for S.BUS  [FUSBS-01A]

How the altitude vario module works

This Futaba FUSBS-01A S.BUS sensor measures ambient air pressure and converts it into barometric altitude and vario readouts that are sent via S.BUS to your telemetry setup. It is intended for use with S.BUS-enabled receivers and telemetry displays on model aircraft and other RC craft that utilise pressure-based altitude data.

Fit the unit by plugging it into the S.BUS bus or an S.BUS-compatible receiver socket and let the system enumerate the sensor on the telemetry chain. Once connected, the module supplies pressure-derived altitude and climb/descent metrics for display or recording.

Prior to installation, verify that your receiver and transmitter support S.BUS telemetry sensors and barometric data. Consult Futaba's product literature for exact mounting options and any electrical installation notes.
