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.
