CRFS und ExpressLRS (ELRS)
Die BEASTX-Geräte unterstützen das CRSF-Übertragungsprotokoll, das von Team Blacksheep (TBS) für ihre Crossfire-Funkmodule entwickelt wurde. Dieses Protokoll ist für viele OPENTX/EDGETX-Fernsteuerungssysteme verfügbar, insbesondere mit dem ExpressLRS (ELRS) Übertragungsstandard und findet immer mehr Beliebtheit, nicht nur für Drohnen, sondern auch für Hubschrauber und Flächenmodelle. Das Protokoll ermöglicht sehr hohe Übertragungsraten und ist sehr benutzerfreundlich.

Verbindungsschema
Du kannst CRSF nur zur Übertragung von Steuerdaten an Dein BEASTX-Gerät verwenden. In diesem Fall verbinde nur die TX-Leitung des Empfängers mit dem DI1/IO1-Port Deines BEASTX-Geräts.
Um den Telemetrie-Rückkanal zur Fernsteuerung zu aktivieren, verbinde die RX-Leitung des Empfängers mit dem SYS-Port Deines BX-Geräts. Wenn der SYS-Port bereits von einem SRXL2-Gerät (Spektrum AVIAN ESC) belegt ist, kannst Du alternativ die RX-Leitung mit dem DI2-Pin verbinden (nur MICROBEAST PLUS / ULTRA).
Um SYS für die Verbindung des BLE2SYS / USBSYS zur Nutzung der StudioX-App zu verwenden, trenne einfach den Empfänger vorübergehend von SYS, schalte Deine Fernsteuerung aus und starte Dein Gerät neu. Dadurch wird der "normale" SYS-Betrieb für Programmierzwecke aktiviert.
| DI1 / IO1 | SYS | SAT | DI2 |
|---|---|---|---|
| TX-Leitung | - | - | - |
| TX-Leitung | RX-Leitung | ESC-Telemetrie | - |
| TX-Leitung | SPEKTRUM SRXL2 ESC | - | RX-Leitung |
MICROBEAST PLUS
Der Motorsteller bzw. das Gas-Servo ist am CH5-Port angeschlossen. Falls erforderlich, wird die Telemetrie-Datenleitung vom ESC mit dem SAT-Port am 5-Pin-JST-Port an der Seite des Geräts über einen Adapter verbunden.
MICROBEAST ULTRA
The ESC or throttle servo is connected at IO2 port. If needed the telemetry data line from the ESC is connected to the SAT port at the 5-pin JST port at side of the device using an adapter.
NANOBEAST
The ESC or throttle servo is connected at CH1 port. If needed the telemetry data line from the ESC is connected to the SAT port.
Radio setup
When using a ELRS receiver make sure to enable the CRSF output using the web interface of your receiver. Using the RADIOMASTER ER-series receiver you can change the output signals of the receivers as needed. Here usually we set the CH2 and CH3 outputs of the receiver to RX and TX for the CRFS input and output. The smaller RADIOMASTER receivers only come with RX and TX outputs, so there is nothing special to do here. To access the web interface, power up the receiver, wait for one minute until the receiver flashes quickly, then connect your computer or smartphone to the new wifi network 10.0.0.1 (Password: expresslrs).
For the ELRS settings in the radio we recommend using the D500 Wide mode or 333Hz Full mode. Note that only in "FullRes" mode all channels have full resolution. When using channels 6 and above only for controling the ESC, gyro and similar control functions, the "Wide mode" should be OK as well. (Please note that CH5 is not available as this is used as binary switch channel!). We mostly use D500 mode which is working very well. The BX devices can even use the 1000Hz mode but we do not recommend this mode due to restricted radio range and lack of safety options. Also this will not give any benefit when driving servos at a much slower rate.
BEASTX setup
In order to use your CRSF/ELRS 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. By default the BEASTX system has a preset channel order that fits the AETR scheme of your OPENTX/EDGETX radio. If needed you can change the channel ordering in RECEIVER MENU of the BEASTX system.
| Channel | Function |
|---|---|
| CH1 | Roll / Aileron |
| CH2 | Pitch / Elevator |
| CH3 | Thrust / Collective |
| CH4 | Rudder |
| CH5 | - (Don't use!) |
| CH6 | Throttle |
| CH7 | Gain |
| CH8 | Attitude/Rescue (optional) |
| CH9 | Governor (optional) |
| CH10 | 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. You can perform basic setup procedure in SETUP MENU when init sequence was completed. For further information about RECEIVER MENU setup, see next section.
NANOBEAST
Connect the TX line of the receiver to DI1 port and power up NANOBEAST. 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. Please note that when the RX line of the receiver is connected to SYS port, you must disconnect the receiver from SYS temporarily, switch off your radio and power cycle your device. It will then enable "normal" SYS operation for programming purpose. For further informations please refer to the StudioX instruction notes.
