chony If you are referring to the Yamaha IDC site, this can only be connected to via the Tyros 2 itself and not from a stand alone PC.
If you have registered your serial number and received the free wireless usb adaptor, you can set it up to view all of the IDC's contents from within the T2. If you are having trouble connecting can you ring your local technical support helpline?
