The iPad is typically connected over Wi-Fi. Do you have Delora software's KymaConnect? If so then KymaConnect will use the built-in Wi-Fi of your Mac. Otherwise, you could connect a Wi-Fi hotspot to the Ethernet port on the back of the Pacarana (not expansion port B, but the port labeled Ethernet).
If your computer and Pacarana are both connected (via Ethernet cables) to a local area network that also has Wi-Fi, the Pacarana will show up in Kyma Control if your iPad also connects to that Wi-Fi network.
