Connecting an Elecraft setup

I have an Elecraft KX3, KXPA100, PX3 station how do I connect a digirig mobile to this setup and the computer. I ordered the digirig with the suggested cables. Specificaly how do I connect my computer. Thank you.

The recommendation is to first just configured naked transceiver with Digirig.
Once you have that working you can move to adding amps and other equipment knowing that the previous connections and settings are working.

Thanks for the advice. I’ll start by configuring the naked transceiver with Digirig and then add amps and other equipment.
