To download/transfer files to computer, you need 2 softwares from yamaha website. USB MIDI drivers and MUSICSOFT DOWNLOADER.
Install drivers first,and then Musicsoft Downloader.
Connect keyboard to PC/notebook by USB cable.
Run Musicsoft Downloader.
If you click "Electronic Musical Instrument" in the Musicsoft Downloader display.and then "System Drive", a file named "08PG76BUP" will appear in the lower right corner of the Musicsoft Downloader display. This is the backup file that will transfer to computer.
Usually yamaha came with CD-ROM that contain divers and softwares + user manual,so you don't need to download.
I hope this helps.
Regards.

Here it is in PDF format for you! Use this link:

http://www.manualowl.com/m/Yamaha/DGX-200/Manual/151764

It doesn't use a USB to MIDI adapter (such as the UX-16.) It has an onboard MIDI controller and uses a standard USB A-B cable. You just need to install the driver from the CD-ROM or here, and plug it in. You can get the manual from the same page or here. Setup is on page 99.

Here you go:

There is a an "output phones" to put the headphones into on page 17 of the manual here.

Hope this helps!

Your Yamaha DGX 203 Portable Keyboard - USB-MIDI Driver Version 1.2.2 ie. for OS Win9x/ME.

Yahama site does not have the Win7(x64) Drivers ie. USB-MIDI for your Keyboard Model DGX-203

But you can try the USB-MIDI Driver Version 3.1.0 for Windows(R) 7/Vista/XP 64bit for Model DGX-520 @ http://usa.yamaha.com/products/musical-instruments/keyboards/digitalkeyboards/dgx_series/dgx-520/?mode=model

I can't assured you that it will works on your system. Since your Keyboard is no longer in production, I doubt Yahama will provide you with the official USB-MIDI drivers for your Keyboard even you requested for it.

I guess this is an option you can try and hope it works & good luck.

Regards.
