Most discretes don't change, and if they do chances are high you can also obtain them in Pronto Hex format, which can be easily imported into the MX-850 software.

And one thing to remember, when URC adds a new specific device model number to the database, nine times out of ten all that's doing is referencing one of a handful of "master" codesets available at the end of the list - it doesn't actually customize anything for that specific device. So, you could spend hours fighting to get an updated database that shows your model, only to find that device is configured to use a codeset you had all along.

So, all I'm trying to say... if you don't have the most recent database, it's very likely nothing to worry about. If you're looking for an update because you're having trouble controlling your device, or need specific commands not otherwise available to you, just ask and I'm sure we can help.
