Short answer: Currently, attaching one end of an ethernet (cat5/6) cable to the Akai Force and the other side of the same ethernet cable to anything within the Denon DJ Prime (closed) ecosystem (eg. sc5000 player, Prime 4) will make precisely nothing happen. I say “currently” because back in January there was a long thread on here re: [Link port on the Akai MPC Force], and a Denon DJ employee responded
“We have plans to integrate the two devices in a future release just so you are aware when you’re ready to purchase a product from the Prime Series.”
The assumption was that said integration would not need the helping hand via Serato.
