Hi, What is the cheapest Radio Shack remote that will let me learn discrete codes for my MX500. Model # is appreciated! Thanks.

There's the 15-2102, going for $8, but it's a 4 in 1, it might not have any audio codes. Then there's the 2103 for $14.

I have the 4 in 1 15-1993 which was about $15, and probably has been discontinued..........but it worked for all of me discrete needs.

I recently also posted an FYI that after buying this......I realized that the Comcast remote that came with my digital box also has the undocumented ability to do all the same codes.

I also just realized that my stock Onkyo receiver remote is actually a pretty good remote! It has a good learning/macro ability, and on/off buttons. I'm going to check if it will do the trick tomorrow!

ps - loving the Mx500. With it controlling the X10 lights its really a great addon to my home system. The IR 543 also seems a lot more stable (not as likely to lock up) when using dimmming controls. Anyone else notice this?

So I find these remotes. Where do I go for the programming for the discrete codes?

Find the setup code for your particular device, then see if there are advanced codes available for that setup code.
