MACBOOK PRO M4 CHIP/ TRAKTOR P 4 / CDJ NEXUS 900 CONNECTION?

HI Ya'll.

I have an Xone 96 using the USB 1 connected to the M4 Max Laptop, OS 15.2 Sequoia.

Running Traktor Pro 4 V.3.11.1 17

CDJ 900 NEXUS Running V. 1.31 / Connected to line input 1 for the Left deck - Right Deck connected to line/ch 2. With the Traktor Control CDs playing track #2.

-How do I get the CDJs to control the software?

What I've come across has not helped me connect this ..

What are the analog connections, and what are the digital settings needed in Traktor Prefs?

Many Thanks,

Jay
