Disklavier

I decided to go with a cable from "To Host" to 9 pin serial port. I
downloaded the CBX driver and extracted the files. I was just reading
on the yamaha site that I should now double click the 'setup.exe' file
and follow the prompting windows. There is a window I need to fill out
and I don't know how to answer the question. Can someone help me with
this? The question reads:
"9) Select the appropriate radio button in the 'MIDI Output Ports'
dialog box to choose either 'Use single MIDI output port' or 'Use
multiple MIDI output ports'."
Should I choose single or multiple? I don[t know what it means. I want
to send and receive from and to the computer and Disklavier. Right now
the Disklavier is the only midi I am connecting to the computer
although I might be hooking other midis up in the future. I don[t know.
Thanks, Mike
