# Network

All relevant onboard components are connected to each other via an ethernet switch. Some components, such as the Herelink Airunit, have static IP addresses listed below. The onboard Jetson has a single physical ethernet port, and comes preconfigured with multiple static IP addresses to communicate with the other onboard components.

## Jetson Access

The Jetson is assigned a static IP address of `192.168.35.1`, and allows an SSH connection on this IP.  **This IP should not be changed.**

## Internet Sharing

### MacOS

To connect to the Jetson, first set the IP to be on the same network as the Jetson. To do this, go to **System Settings -> Network** and select the interface that appears when the ethernet connection is physically formed with the Jetson. For example, **AX88179A** is the example interface. Select this interface, and then **Details -> TCP/IP**. Make sure that **Configure IPv4** is set to **Manually** and that an IP on the Jetson's network is in the **IP Address**, for example **192.168.35.2**.

To enable internet sharing, go to **System Settings -> General -> Sharing** and turn on **Internet Sharing**. At the top, make sure to select  **Internet Sharing: On** and in the section **To devices using** turn on the interface that is connected to the Jetson.

## Herelink

The Herelink Airunit is assigned the IP address `192.168.144.10`, and the Herelink controller has the IP `192.168.144.11`. To communicate on the Herelink network, the onboard Jetson is assigned the IP `192.168.144.1`. **This IP should not be changed, as it will completely sever communication between the Jetson and the drone controller.**&#x20;

## Payloads

Some payloads, such as the Gremsy Vio and GoPro Hero 12 Black, may require their own networks in order to communicate with. For a payload such as the Vio, the Jetson needs to be manually assigned an IP on the same network, which is `192.168.12.x` . A payload such as the GoPro will assign an IP to the Jetson on a new interface that is created, in which the IP is determined by the serial number of the GoPro. In this case, there is no need to assign any further IP addresses.
