1. **Connection Management**: This is the first step where you select the COM port and connect to the Box.
2. **Device Name**: Rename the device as desired.
3. **Fan Speed and Default Mode**: Adjust the fan speed from Low (L) to High (H) to reduce noise. Additionally, the default mode allows you to set the Box to always start in either USB or OTG mode.
4. **Control Panel and Modes**: This section lets you quickly configure all devices to OTG mode, USB mode, or turn off and restart all devices at once. Furthermore, you can optionally enable devices via OTG or LAN as needed.

The above covers all the features and instructions for using the GenFarmer Box Controller. If you have any questions or concerns, please feel free to contact us via [**TELEGRAM**](https://t.me/genfarmerchat) or the [**Facebook Group**](https://www.facebook.com/groups/733350245650960)

# 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://genfarmer-support.gitbook.io/genfarmer-eng/instruction-manual-for-using-the-genfarmer-box-controller.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.
