The 9200 was intended to be a consumer remote and as such is very limited in the things you can do. The 9300 was intended to be installed by professional installers.
I think that you may not be happy with the 9200 and likely want a 9400 or a 9600 instead, especially if you want to do JavaScript on the remote which is possible with these models.
