### Long Range Pixhawk Modem von RF Design  - 868Mhz **in der neuen EU Version!**

**Zum Anschluss am Cube (Pixhawk 2.1) oder der Holybro PX Serie empfehlen wir folgendes Kabel (separat erhältlich, Artikelnummer: 5717 /** CABLE-R9X-MULTI-30cm  **EAN:  4250902356170 )**

Dieses Kabel ist vorkonfektioniert um ein RFD868Mhz Modem an einen der Telemetrie Ports des Cube (Pixhawk 2.1) oder auch der Pixhawk 4 Flightcontroller anzuschließen.

Die 5V Spannungsversorgung erfolgt hier dann separat über einen Servostecker (z.B. per UBEC, oder Servorail der Pixhawk).&#x20;

**Dies ist die empfohlene Verkabelungsmethode um das Pixhawk Carrier Board nicht zu überlasten.**

**Achtung! Das schwarze Dreieck am Kabel zeigt auf Pin1. Die rote Ader ist dann Pin4. Ein falsches anschließen des Kabels kann das RFD Modem und weitere Komponenten beschädigen!**&#x20;

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.premium-modellbau.de/premium-modellbau-portal-fuer-anleitungen/rfd/rfd-rfdesign-ubersicht/rfd868x-eu-modem-868mhz.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
