1. Connecting the serial port on the computer to the YDP-223’s TO HOST jack
Connect the computer’s serial port (RS-232C or RS-422) to the YDP-223’s TO HOST jack.
With this connection, the YDP-223 functions as a MIDI interface. Therefore, you do not need a special MIDI interface.
Connection
Use a special serial cable (page 49) to connect the computer’s serial port (RS-232C or RS-422) to the YDP-223’s TO HOST
jack.
Type of serial cables and connection pin assignments
Depending on the type of computer you connect, use one of the following serial cables.
Note for Windows users
(regarding the MIDI driver)
To transfer data via the computer’s
serial port and the YDP-223’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
web site:
