The Dual Input Servo Channel Expander EX5 is an intelligent bus manager compatible with several radio control systems. The device converts serial bus signals from up to two receivers to either standard PWM servo outputs or configurable bus outputs. It offers up to five configurable and high-power servo ports with optional period and fail-safe settings.

The EX5 is a perfect choice for models with complex wing or tail mechanics where multiple servos may be connected to a primary receiver/receiver using just a single cable. In addition, if you are running out of receiver channels simply connect additional SE2/SE4/SE6 to the EX5 serial line/s and freely assign any channels.

The EX5 offers flight stabilization (Optional) using the integrated MEMS gyroscope/accelerometer. Up to three configurable flight modes can be used, each with different stabilization gains and settings. In connection with other devices from our production, such as SE4 or SE6, you can create a complex installation with just a few signal/power cables.

Specifications and Features
– Supported Protocols: Jeti EX, Multiplex M-LINK, Graupner HoTT, Futaba S.Bus/S.Bus2
– Small dimensions and high current throughput via the integrated MR30 power connectors.
– Telemetry (RC system dependent): Temperature, Voltage, G-Force (+/-30G), Attitude (Roll/Pitch/Yaw).
– Gyro-stabilized servo outputs, EX Bus, SRXL16ch. or S.Bus.
– Flight stabilization offering 3 configurable flight modes (Manual/Acro/Horizon).
– Automatic detection of serial data/telemetry after startup.
– Configuration through the transmitter or external terminal (JETIBOX/SMART-BOX).

Advance Model Installation
Attach the required servos or additional bus devices (SE2/SE4/SE6) to the EX5 (ports 1-5). Connect up to two receivers through their bus outputs. In the case of a single receiver, always connect the primary RX to the RX1 port of the EX5. Turn on the transmitter and apply the appropriate power source to the EX5. The status LED starts blinking as soon as the EX5 detects the signal on the serial line. Please note that both receivers have to use the same data protocol (S.Bus, EX Bus…).





Flight Stabilization (Up to 16 Channels)
Install the EX5 in parallel to the flight axes, as close to the center of gravity as possible. By default, the axes printed on the device point in the direction of flight: X-Front, Y-Right, Z-Top. In case you need to install the EX5 in a different direction, please keep in mind that the arrows on the device must be parallel to the flight axes. In such a case, the resulting orientation of the device must be set in the configuration menu.


Stabilization Modes and Channel SwitchYou can use up to three flight stabilization modes operated by a dedicated transmitter channel.

• Manual – Flight stabilization is disabled and the EX5 just passes channel data from the receiver(s).
• Acro– Standard flight stabilization with configurable rate/heading gains. You can decide which axes will be controlled by just rate gains (so-called Normal or Damping mode) with heading gain disabled. With additional heading gains, the Heading hold function will be active.
• Horizon– The stabilization function is similar to the Acro mode, additionally the model returns to a horizontal position if the Aileron/Elevator sticks are released.

Stabilization GainsThe stabilization gains can be set independently for each axis and each flight mode. There are six parameters in total and in the configuration menu, you edit the value for the currently active flight mode.
