*1 : This is the cable which I made referring to the following page.

[How to make a MIDI adapter] (Written in Japanese)

*2 : Modification for supplying voltage (9V) to the level conversion IC
from 7pin (RTS line) of the serial port is given to this cradle.

*3 : Since it is said that PLPH-F3W did not work with YAMAHA CBX-K1XGB,
there may be the other sound modules with which it doesn't work.
