JETI EXBUS
EXBUS is a very versatile protocol. Not only it can send control data to the flybarless system, it can also be used to transmit telemetry data and even display menu on the radio or JETI box. You can connect the EXBUS data line at different ports at your MICROBEAST or NANOBEAST. Make sure that the receiver output is set to EXBUS (not UDI, SPPM or else).
| Port | Telemetry | JETIBox menu |
|---|---|---|
| DI1 | no | |
| SYS | yes | yes |
| DI2 | yes | yes |
Using EXBUS to control your helicopter is possible with any of the BEASTX devices. Connect the receiver's EXBUS port with the DI1 / IO1 port of your BEASTX system using one of the provided standard servo wires.

The ESC or throttle servo is connected at CH5 / IO2 output.

For bi-directional telemetry connect the EXBUS signal wire either to the SYS port or to the DI2 port of your MICROBEAST PLUS / ULTRA. When using the DI2 port an adapter from standard servo connector to 5-pin JST is required as shown below.

MICROBEAST PLUS
The ESC or throttle servo is connected at DI1 port. If needed the telemetry data line from the ESC is connected to the CH5 port.
MICROBEAST ULTRA
The ESC or throttle servo is connected at IO1 port. If needed the telemetry data line from the ESC is connected to the IO2 port.
NANOBEAST
The ESC or throttle servo is connected at CH5 port. If needed the telemetry data line from the ESC is connected to the SAT port.

BEASTX setup
In order to use your EXBUS receiver you have to scan the input type in the RECEIVER MENU of your BEASTX device and set the correct channel ordering
for your radio system.
| Channel | Function |
|---|---|
| CH1 | Throttle |
| CH2 | Roll / Aileron |
| CH3 | Pitch / Elevator |
| CH4 | Thrust / Collective |
| CH5 | Rudder |
| CH6 | Gain |
| CH7 | AttitudeControl (optional) |
| CH8 | Governor (optional) |
| CH9 | Aux channel (optional) |
(The optional functions are described in the section Optional features.)
MICROBEAST PLUS / MICROBEAST ULTRA
Push and hold the button on your MICROBEAST and power up the device. Menu LED A will flash instantly. Now release the button. Push again to start the scan process. When scan was successful, Menu LED B will show up. Now push and hold the button for 2 seconds and release in order to load the default channel assignments. If needed you can set up your telemetry devices at Menu LEDs L & M, if applicable; push button briefly to skip. Finally teach throttle failsafe position at Menu LED N by bringing the throttle in lowest position on your radio and push the button again. Now your MICROBEAST will start with init sequence.
For further information about RECEIVER MENU setup, see next section. Then perform basic setup procedure in SETUP MENU.
NANOBEAST
Power up NANOBEAST. Then connect the push button to SYS port. Push and hold the button for 2 seconds, then release. The Status LED will change color or go off. Push the button again to start the scan process. When scan was successful, the Status LED will flash twice. Now push and hold the button for 2 seconds and release in order to load the default channel assignments. If needed you can set up your telemetry devices at Menus L & M, if applicable (Menu L = Status LED flashes long once and then 5 times, for Menu L 6 times); push button briefly to skip. Finally teach throttle failsafe position at Menu N (Status LED flashes long once and then 7 times) by bringing the throttle in lowest position on your radio and push the button again. Now your NANOBEAST will start with init sequence. For further information about RECEIVER MENU setup, see next section. Then perform basic setup procedure in SETUP MENU.
Setup with StudioX
You can also use the StudioX app to start receiver scan and perform further setup steps. In this case open the Control menu in StudioX and click the SCAN button in this menu's screen. For further informations please refer to the StudioX instruction notes.
