I picked up the RCA remote, and figured out how to enter the EFCs.
The good news: the EFCs for discrete power on (device 0650; 20005 and 21029) worked!
The bad news is that the discrete input EFCs did not. (and those are the ones I really need)
I am thinking that panasonic has recently moved the ball here, since the obvious workaround (input, then number from pad) does not work, and googling posts from a few years ago indicates that it *used* to work. Maybe it still works for the ST.
I will try to hang out on the JP-1 site; it is a bit technical, so I have some studying to do before I dare post.
But if anyone has a working EFC for the S series inputs, I would be very grateful.
>> One small problem I am having. As far as I can tell, there is no discrete off, and no codes for the inputs on the remote (the "last" button has some functionality, but not enough for me since I use all three inputs). The discrete off is no big deal, but the lack of discrete input codes means that there is no obvious graceful way to write macros to switch devices. I am assuming that there are hidden codes that companies like harmony use, but it would be a drag to have to buy a new learning remote.
> I'm pretty sure the S60 is as capable in this area as my ST60, which supports discrete on/off and discrete inputs for all but the built-in TV tuner. You may be able to find an old remote on eBay that has physical buttons for these functions, but the long term, general purpose solution for all devices is to get into JP1 remotes. The RCA RCRP05B is a perennial favorite and cheap, less than $15 or so. It is a decent remote in its own right, but I use it to teach my remote of choice, the Sony RM-VL610. I've been programming the RCA with a JP1 cable and RMIR software, but I've recently learned it's possible to input codes by hand, which will do nicely when you just need a few codes to teach another remote. For more on this, see the thread here, and this site BTW is the main site for all things JP1:
If you scroll down to the list of recalculated EFCs, you will find discrete power and inputs. I assume they work; I know the one for Sleep does, as I tried it. (The thread was motivated by someone asking here about the Sleep command and me wondering if there was an easier way than buying/constructing a JP1 cable and getting into RMIR.)
