I have been asked to program an old Genesis MX 900. I understand that the early ones used the MX900 editor and the newer ones use the CCP editor. I have both. How do I tell which to use without simply trying them. The urc website says using the MX 900 editor on a new model will brink it. Can I use the CCP editor on both the old and new models? Any know what serial numbers work with CCP and which with MX 900.

Thanks.
