Question: can you link cdj 900?
Answer: This is the simplest way to create the network is to plug in one Ethernet (cat5) cable into each CDJ. Models that support this are the CDJ 900, 2000, 900NXS, 2000NXS and 2000NSX2. This allows you to plug in one USB into one CDJ. Then press the "LINK" option on the other CDJ.
