Connecting to a Personal Computer
Although the CLP-411/511 can be connected to a personal computer via the
MIDI IN/OUT connectors and a MIDI interface, the TO HOST connector and
HOST SELECT switch allow direct connection to Apple Macintosh or IBM-PC/AT
personal computers for sequencing and other music applications without the
need for a separate MIDI interface.
Connect the TO HOST connector of the Clavinova to the modem or
printer port on your Macintosh, depending on which port your MIDI
software is using for MIDI data communication, using a standard
Macintosh 8-pin system peripheral cable. Set the HOST SELECT
switch to the “Mac” position.
You may also have to make other MIDI interface settings on the
computer side, depending on the type of software you use (refer to your
software owner’s manual). In any case the clock speed should be set to
1 MHz.

•Data transfer rate: 31,250 bps.
NOTE
•When using the [TO HOST] terminal of the CLP-411/511, first turn the
power off on both the CLP-411/511 and the computer before connecting
the cable. After connecting the cable, turn the power of the computer on
first, then the CLP-411/511.
•When not using the [TO HOST] terminal of the CLP-411/511, make sure
the cable is disconnected from the [TO HOST] terminal. If the cable is left
connected, the CLP-411/511 may not function properly.
•When the HOST SELECT switch is set to “Mac”, “PC-1”, or “PC-2, no
data transfer occurs via the MIDI connectors. To use the MIDI connectors
for connection via a standard MIDI interface, set the HOST SELECT
switch to “MIDI”.
•If your system doesn’t work properly with the connections and settings
listed above, your software may require different settings. Check your
software operation manual and set the HOST SELECT switch to the
position that provides the appropriate data transfer rate.
