When you are in PPENG open your TSU7500 file as normal. Then click on the menu "File" - "Save Configuration As" then look in the pop-up that opens, you will see at the very bottom "Save as type" if you click the drop-down list, you should see the various choices of TSU7000, TSU7500, RU980 and RU990. Choose RU990 and you should then have an RU990 file.
Hope that assists
