NAD D 3020 amplifier

But now I encounter the problem of programming the remote for the right devices, which are as follows:

First, NAD D 3020 amplifier. The default NAD codes in the remote don't seem to work (I got as far as turning the device off, but nothing else). However NAD has released a document with the codes, which looks like:

Code: Select all

Please tell me this information can be used to generate a device upgrade (and how), or point me to the appropriate upgrade. The original remote is as good as broken, so using it for learning codes is almost hopeless.

Once you get the connection issues sorted out with your URC-6440 remote, you will be able to use it to learn signals from your remotes and then see the results on your computer.

In this case it's easy to translate the codes that you posted into codes that you can use in RM, just convert the hex to decimal and you're all set.

I did that and created this...

Sorry, I should have reported back earlier, but you missed the part where I said:

The "tricky" part was understanding that I should not use the hex codes as such, but I had to invert them... which was then equivalent to using the dec codes directly as OBCs.

No, I got that about the NAD remote, I was talking in general.

I did miss that, where did you post about it?

Yeah, we could have helped with that as we know this stuff.

I didn't post anywhere else, just uploaded the file. I saw no obvious place to post an "announcement". I also uploaded the device upgrade files for my other devices, should I post about them somewhere else?

Only if you have posted asking for help with them, otherwise folks might go to the effort to create files for you, only to find that you did it yourself.
