Yamaha CLP-611, CLP-811

2. Connecting to an IBM-PC/AT Series Computer

Connect the TO HOST connector of the Clavinova to the RS-232C port on your IBM compu-

ter, using a standard 8-pin MINI DIN → 9-pin D-SUB cross cable. Set the HOST SELECT

switch to the “PC-2” position.

Refer to your software owner’s manual for information on any settings you might have to make

on the computer side.

●“PC-2” Cable Connections

• 8-pin mini DIN → 9-pin D-SUB cable. Use a “PC-1” type cable if your computer uses a

25-pin serial port.

• Data transfer rate: 38,400 bps.

●“PC-1” Cable Connections

• 8-pin mini DIN → 25-pin D-SUB cable.

NOTE

• When using the [TO HOST] terminal of the CLP-811/611, first turn the power off

on both the CLP-811/611 and the computer before connecting the cable. After

connecting the cable, turn the power of the computer on first, then the CLP-811/

611.

• When not using the [TO HOST] terminal of the CLP-811/611, make sure the cable

is disconnected from the [TO HOST] terminal. If the cable is left connected, the

CLP-811/611 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 connec-

tion 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.
