I was looking for a solution to replace all the remote controls of my equipment. The irplus android app was doing the job for the rest of my devices, but not for the naim amp.
I read that the narcom 5 remote control works with the RC5 protocol from Phillips. And I’ve found information of its reference codeset in wikipedia https://en.wikipedia.org/wiki/RC-5, but I needed to confirm the system code used (0x10 Preamp ) and the carrier fequency (36khz). In this forum there are people interested in this issue, but I didn’t found specific information
For those, like me, interested in alternative methods to control their amplifiers, Naim support team has released the code list.
In my case I use the android app “irplus”. You can find the related configuration file and the RC5 code list used by Naim in the irplus github page https://github.com/irplus-remote/irplus-codes.github.io/issues/473
I didn’t succeed in getting the discrete commands to work. In particular, the fast volume codes did’t work for my naim nait xs3. Due that I set the repeat frequency to 50ms to get the regular volume works in a proper way
