Narcom 5 Remote - Nait XS3 and Rogue RP-7

I just set up a new Rogue Audio Rp-7 Preamplifier for a different system and I also have a Nait XS3 with the Narcom 5 controller for an older system. Both remotes control both pieces of equipment at the same time (increasing volume, mute, etc) and I’m wondering if there is a way to change the frequency channel on the Naim so it doesn’t receive signal from the Rogue controller or vice versa.

If not that, then could I program each piece of equipment to a different soft key?

Any help would be much appreciated.

Naim use the Philips RC5 protocol, so it’s likely here that Rogue use the same too. Are the systems located together in the same place? If so, I can see how that might be a problem.

The easy fix is to block the IR of whichever unit you don’t wish to be controlling.

IIRC RC5 does give the option to change a channel to avoid clashes. If I were you I would contact Naim support (or Rogue Support?) here and ask them.
