Under that tab, it doesn't really say what it is. But on the first page you can see that it states those columns are "Remote Code: RC-5/ RC-5 Ex. Format"

At first I thought they were RS-232 codes. But I just noticed they are RC-5/RC-5 ex.

It's been a long while since I've worked with Pronto Pro. But couldn't that software generate IR codes out of RC-5/5 EX? Either by itself or with a SW that a member has created on here?

Or if it comes down to it. Download it to a Pronto and learn the IR codes from it.
