CDJ 850 does NOT support this function. It is supported only by models with an ethernet port on the back - CDJ900,900NEXUS,2000,2000NEXUS. You can connect players and pc via ethernet cables to the switch or router or built in swich in DJM2000. They create an individual LAN network to communicate between each others (like drag and drop tracks on linked player icons from linked pc's recordobox, library link, tempo sync etc).
