Hi,
I have a Harmony One (along with various other Harmony models). I also have a RadioShack 15-2104 6-in-1 remote that has the 6 pin JP1 port under the battery cover. I bought that remote many years ago but never used it so it's brand new. I seem to remember that I bought it in order to input discrete codes and then learn them to another remote (like the Harmony). This is what I'm trying to do:
I have a Denon 4311 AVR that has a discrete function that the remote requires navigation through the menus in order to execute the command, which is HDMI output (AMP or TV). I have found the discrete codes for the 4311 which include the codes for this. The discrete codes include:
HDMI Audio Out (Toggle)
HDMI Audio Out TV
HDMI Audio Out Amp

My question is, how do I implement these codes. Do I need a Pronto or RC5000 remote or can I get these discrete code commands programmed to my Harmony with the remotes I already have.
Thanks in advance.

You could load them into your RS remote IF you had a JP1 cable (I'm guessing you don't), then teach your Harmony with it. In this case, just email the pronto hex you already have to [email protected] and ask that they add the commands to your account. If you don't have the pronto hex, you can make it with IRScrutinizer, and the JP1 upgrade files I assume you found.

Thanks for the suggestions. I emailed Logitech and asked them to add the discrete codes to my account. I got no reply so I emailed William Wong at Logitech and he got the ball rolling and I eventually got what I asked for. Works like a charm!
Thanks again.
