I received a spreadsheet with all the codes from Onkyo/Integra and for every command there is a pronto code(hex/binary) in 3 different pronto ID's, I basically click on the code- highlight the complete hex command and copy to the clipboard, then go into the 900 editor and in the browser click on the "hex" box and in that box click on the paste icon, at that point the hex command shows up in the box. Now I click the "drag hex" button and drag to the physical button I would like the command to reside at but the editor does not show anything on that specific button( by pointing your mouse at the button it should show a "L" under the button). But no matter what I do it never actually transfers the hex command to the button. I believe that I have the process down correctly but cannot make it work. I do understand that the URC editor will only accept Pronto style hex, altho I don't know if the info given by Onkyo is correct( it just says its in a Pronto format)
