# Connect

## USB-C

Connect the USB-C port to your PC. The Jetson appears as a USB network device at `192.168.55.1`:

```bash
ssh jetson@192.168.55.1
```

The web UI is reachable the same way at <http://192.168.55.1>.

The same cable also carries a serial login console — see [USB-C Console](/products/flight-controller/jetson-pabs/ark-jetson-pab-carrier-v3/developer/micro-usb-console.md).

## WiFi Hotspot

On first boot, if no known WiFi network is available, the Jetson brings up a hotspot:

* **Network**: `jetson-<serial>`
* **Password**: `password`

Connect to it and open <http://jetson.local>.

{% hint style="info" %}
**MHF4 antenna cables are required for WiFi and are not included.** Compatible MHF4 to RP-SMA cables: [option 1](https://www.amazon.com/female-Pigtail-Antenna-Extension-wireless/dp/B07GTL2G69), [option 2](https://www.amazon.com/dp/B076SGTMFS). Some bundles ship without the WiFi card — the hotspot only appears when a WiFi card is installed.
{% endhint %}

## Ethernet

Connect the 4-pin JST-GH Ethernet port to your network — the Jetson requests an address over DHCP. The onboard switch also connects the flight controller and the Pixhawk Payload Bus, see [Autopilot Connections](/products/flight-controller/jetson-pabs/ark-jetson-pab-carrier-v3/using-ark-os/autopilot-connections.md).

Once the Jetson is on your network:

```bash
ssh jetson@jetson.local
```

# 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.arkelectron.com/products/flight-controller/jetson-pabs/ark-jetson-pab-carrier-v3/setup/connect.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.
