JP1 Remotes

A couple of elementary questions:

1. When a button's function is specified in the remote's ROM and an upgrade file which doesn't assign any function to the button is loaded into the remote, does the button have the same function as it did before the upgrade?

2. What's a subdevice?

Thanks,

When you create and load an upgrade into your remote, you are basically adding one more setup code to the big list of setup codes that are already in the remote. So therefore, just like with the ROM setup codes, when you select a setup code, what you get is what you get. Just because a button may be defined in some other setup code makes no difference to you if it's not defined in the setup code that you happen to be using.

IR signals have various codes defined in them, a basic signal will have a single device code and a button code (aka "OBC"), but some signals have a few more bits & pieces in there, such as a sub-device code or a unit code.

I see. Thanks.
