CONNECTIONS

Leave your entire system (including the DN-C640) turned off until all connections between the DN-C640 and other components have been completed.

■Connection precautions

•Before proceeding with connections or disconnections of cables and power cords, be sure to turn all system components off.

•Ensure that all cables are connected properly to the L (left) and R (right) jacks.

•Insert plugs fully into the terminals.

•Connect the CD output jacks to the amplifier CD or AUX input jacks.

•Connect one end of a straight-through RS-232 serial cable into Communication Port on the back of the DN-C640 and connect the other end into the “RS-232C” port on the back of the computer.

•Connect the DN-C640 to your network using a straight-through Ethernet cable or directly to a non-networked computer using a cross-over cable.

CAUTIONS:

•Before connecting, the POWER ON/OFF switch should be set the OFF position.
