Connecting Raspberry Pi on the air-unit HERELINK v1.1

Hey Everyone,
I am planning to buy HERELINK V1.1 system.
I wanted to know that :-

  1. Can I connect a Raspberry Pi on the air-unit via provided ethernet port so that it can get connected to the same IP network?

  2. Can I ping Raspberry Pi’s IP address from ground unit tablet via Termux app or similar ? ( I will manually install the app) .

CASE : I want to make an app which will install on the ground unit tablet. That app will send and receive data from the Raspberry Pi which is connected to the air unit v1.1 via ethernet port for some IoT application. Is it possible?!
