Introduction
TWIN series receiver features a new stable TW protocol that benefits from simultaneously integrating dual active
2.4G frequency bands. The TW active-active protocol is different from the general active-standby redundancy
solutions, with the TW protocol, dual 2.4G frequency bands are active on the TW series receiver at the same time.
This receiver is equipped with 3×2.4G antennas and designed for RC users who want to benefit from resilience
and long-range in their radio communications.
The configurable channel ports on TW R12 & TW SR12 receivers are a big feature, each channel port can be
assigned as PWM, SBUS, FBUS, or S.Port. By setting the port to use FBUS protocol in the ETHOS system, the
signal control and telemetry can be connected to any device (XACT servos, ADV Sensors, etc.) that supports
FBUS protocol through only one line to achieve bidirectional transmission, also simplifying the model build using
fewer wires.
TW R12 & TW SR12 provides a socket that can be used to connect the switch panel to enable the built-in Power
Switch function, and both receivers use a set of standard XT30 plugs which also provides a safe and efficient way
to provide power. By utilizing together with current overload wires on the channel ports, the connected device can
be safeguarded.
ADV Stabilizer
The TW SR12 offers an ADV Stabilizer function which is an upgrade over the original classical gyroscope
stabilization modes. The ADV Stabilizer offers an advanced mode that provides more programmable stabilized
channels and flexibility.
The classical stabilization mode has been enhanced with 5 additional stabilization channels, providing pin
mapping to each channel in the multiple flight modes like Stabilization, Auto-Level, Hover, and Knife-Edge with
an airplane model.
In the advanced stabilization mode, all the output pins are configurable for stabilization and additional advanced
features such as Stab file sharing, programmable parameters, and developer access, etc.
The advanced stabilizer feature incorporates high-precision telemetry sensors to monitor altitude, vertical speed,
etc. This ADV feature is an additional benefit compared to using a regular S series stabilization receiver.
