I believe that most users will, like me, find a device in the IR Control Pack that is a close match to their equipment. — Staff replied: “If there is a missing command in an existing set, we will add it. In the case of the command you mention, that may be the "FORMAT SCROLL" command that is already there.”
I believe that most users will, like me, find a device in the IR Control Pack that is a close match to their equipment. That is, close but not perfect. There are likely to be a few missing commands. For example, the Default Scientific Atlanta Cable box in my setup is missing the important screen "Aspect" command. It is not immediately obvious how to learn this missing command, since the Roomie system only offers IR learning when the desired device is not available in the IR Control Pack and is not an option in Add Device. Since I am using the listed Default Scientific Atlanta cable box for commands, learning of new or missing commands is not available.
My solution to this problem is to add an imaginary "Auxiliary Device" under control of the iTach WF2IR, IR Port 3. I give this device a model name not listed in the IR Control Pack such as "My Auxiliary" so that all of its commands must be learned. I then add and learn a new "Aspect" command for this auxiliary device and attach this command to a new "Aspect" button on the Roomie control.
This technique allows using the generic devices in the IR Control Pack for the great majority of needed commands and learning only those few commands that cannot be found there.
