A different network may have been connected (for example, link connections were only established between the DJM-2000 and CDJ-2000 or CDJ-900 when the power was last turned on, but when the power was turned on next connections were also established with the router or hub connected to the Internet).

Products supporting link connections such as the DJM-2000 and CDJ-2000/CDJ-900 search for the DHCP server when the power is turned on. If the DHCP server cannot be found, a unique IP address is assigned with the AutoIP function.

Before the power is turned off, if the product is being used in an AutoIP environment with no DHCP server then connects to a network to which a DHCP server is connected while the product is being used, the IP address of the DHCP network rather than that of the AutoIP network is assigned the next time the power is turned on, so the product can no longer communicate with the devices it was communicating with before.

When using the link function, only connect the DJM-2000 and CDJ-2000/CDJ-900, not a router or hub using an Internet connection.
