Joe-

Judging by the amount of posts you have made hear and reading some of your other posts I will assume you know what you are talking about. However, this post reads very confusing to someone who might not understand the difference (ie the OP).

Please clarify.

When using a URC remote all gear is controlled via IR. You can select whether you want to send the IR commands over the air via RF to a URC base station which is then repeated via IR to control IR based gear or you can send the codes directly line of site IR.

As a rule of thumb you can only control RF devices made by the manufacture of the control system. URC remotes can control URC base stations, URC docking stations, URC dimmers, etc.

To control other RF devices you must be able to convert them to IR and obtain the correct IR codeset or remote to learn the commands.
