Connect the LINK terminals using a category 5 class LAN cable. Two CDJs or XDJ-1000 can be connected directly. A LAN hub is required to connect three or more CDJs or XDJ-1000 to make link connections with a DJM.
When using a DJM-2000NXS as the mixer, the internal LAN hub can be used. A separate LAN hub is required to use a DJM-900NXS.
