1. Connecting the serial port on the computer to the Clavinova's TO HOST jack
Connect the computer's serial port (RS-232C or RS-422) to the Clavinova's TO HOST jack.
With this connection, the Clavinova functions as a MIDI interface. Therefore, you do not need a special MIDI interface.
Connection
Use a special serial cable (page 53) to connect the computer's serial port (RS-232C or RS-422) to the Clavinova's TO
HOST jack.

Note for Windows users
(regarding the MIDI driver)
To transfer data via the computer's
serial port and the Clavinova's TO
HOST jack, you need to install a
specific MIDI driver (the Yamaha
CBX driver for Windows). You can
download this driver from the fol-
lowing XG Library on the Yamaha
