CHAPTER 8: Internet Direct Connection (IDC) Service
98
English
Connecting the I/O Center to the
Internet
Connection example 1:
Using a modem with router function
Connection example 2:
Using a modem without router function
Note: Depending on the contract with your Internet
provider, you may not be able to connect two or more
devices (for example, a computer and the Disklavier)
to the Internet. Please check your contract or contact
your Internet provider for further information.
Note: Some types of modems (such as ADSL
modems or cable modems) have multiple ports for
connecting two or more devices (such as computer,
musical instrument, etc.). If your modems have only
one port, an optional router or hub is required in order
to connect several devices simultaneously.
Note: Use an STP (shielded twisted pair) cable for
connection.

a wired LAN connection is supported), visit the Yamaha

Notes on Network Security
The Disklavier Mark IV attempts to achieve a balance
between security and usability in its network
implementation. However, a determined hacker may be
able to defeat these security measures and utilize the
network of the purchaser in an unauthorized manner.
Since each network is different, only the purchaser can
determine whether the security measures discussed here
will adequately protect their network.
The purchaser acknowledges that connection to the
Internet and use of the Disklavier Mark IV Internet
features is done at the risk of the purchaser. In no event
shall Yamaha, its subsidiaries or Yamaha's and/or its
subsidiaries' directors, officers, or employees be
responsible for unauthorized access, loss or alteration of
the data of the purchaser or be liable for any damage from
intrusions.
