Controller V2 Question and Raspberry Wiring

What is the Controller v2 startup supposed to do (Without the Raspberry Pi connected)

Is it supposed to home or do anything when you first power up, or does it wait for commands from the Raspberry PI?

Also, how do you connect your raspberry pi to the satnog controller? I know on the satnogs controller, A is TX, and B is RX, and you have the CTS and DTR pins.

What pins on the raspberry GPIO do you use (assuming your’re using the satnogs pi image)

Also, I’ve heard there’s pre-built images for the raspberry client, where is the file link and what should the file name be?
