This mode is for use with an NEC PC-9801 type computer. The PC-9801 is a very popular
computer in Japan. The specifications are the same as those for “PC-2” mode except for
the baud rate. See “CBX-D5 Specifications” on page 37.

Please consult your Yamaha dealer for more details. If your software does not support the
“TO HOST” connection, the CBX-D5 can still be connected to this type of computer by
installing a MIDI interface card in the computer or by using an external MIDI interface.

using the “PC-2” connecting cable shown on page 33.
