I know this was posted in another of your questions, but the URC online courses are great at helping you understand how URC does things. While you have programmed many other manufacturers systems it is always good to get an overview of how a different manufacturer does things. Not that they are more right or more wrong, but they may be a little different. Once you get those courses under your wing you will be very efficient at programming URC's systems.
Just a suggestion.
