SRXL
SRXL ist ein offenes Datenübertragungsprotokoll, das es ermöglicht, Steuerdaten von einem RC-Empfänger zu einem anderen Gerät wie einem Flybarless-System nur mit einer einzigen Leitung zu transportieren. Das Protokoll beschreibt keine genaue Definition, wie die Daten verarbeitet werden müssen. Es beschreibt nur einen Rahmen, in dem Empfängerdaten verpackt werden können. Jeder Hersteller kann eine eigene ID verwenden, die am Anfang jedes Datensatzes angebracht wird. Das empfangende Gerät, kann so die Nutzlast des Datensatzes korrekt identifizieren und verarbeiten. Mehrere Hersteller von RC-Systemen haben dieses Protokoll in ihren Empfängern implementiert, und die BEASTX Flybarless-Systeme können die Daten dieser Empfänger verarbeiten.

Due to the unique identifier the SRXL protocol allows to automatically detect the function assignment used by each radio brand. So the the usage of SRXL is almost "Plug&Play", indepent of the specific type of radio system that is used. Unfortunately, there are some radio manufacturers that simply copied the protocol from others. So some brands will require to set an alternative function assignment manually as it will not match with this brand's typical channel layout in the radio. Function assignment can be changed in the RECEIVER MENU of your BEASTX device. This will be discussed in a later chapter.
| Manufacturer | Protocol name | Function assignment (ID) |
|---|---|---|
| Spektrum | SRXL | Spektrum |
| BEASTRX | SRXL | Futaba |
| GRAUPNER / SJ HOTT | SUMD | Graupner |
| Multiplex | M-Link | Multiplex |
| JR Propo | X-Bus (B) | Multiplex |
| JETI | UDI | Multiplex |
Connect the receiver's SRXL 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 on MICROBEAST PLUS / ULTRA. NANOBEAST uses the port CH1 for the throttle.

Radio setup
Make sure that the output of your receiver is set to SRXL, X-Bus (B), UDI, SUMD, or whatever it is called.
BEASTX setup
In order to use your SRXL 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.
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 using a Graupner HOTT receiver with SUMD output, you can enable the additional telemetry communication on SYS port at Menu LEDs L & M; push the 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 SRXL port 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 using a Graupner HOTT receiver with SUMD output, you can enable the additional telemetry communication on SYS port at Menu LEDs L & M (Menu L = Status LED flashes long once and then 5 times, for Menu L 6 times); push the 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.
