On a Creative RM-900 remote, I found that it outputs NEC then NEC1 protocol decodes for each function (both protocols have the same Device, Subdevice and Function codes, using DecodeIR.dll version 2.41)
A search of NEC protocols with Device 193 and Subdevice 68 revealed that the original remote Function codes corresponded to Audio Device 0872, with the protocol being NEC1-X2 and the Parameter (3rd Device number) being 22. _________________ "The best thing possible to do with knowledge is to share it". |

Is this just an information post or do you need help with it? _________________ Rob

This is an information post; DecodeIR.dll needs an update to cater for this particular protocol. _________________ "The best thing possible to do with knowledge is to share it". |

DecodeIR reports exactly what's there. It's up to the user to interpret what they see and select the right protocol with the right options. _________________ Rob

I agree with Rob, decodeIR NEEDS to report this as Nec-Nec1, but I'm very happy that you called this protocol to my attention, because I was totally misreading the name of this protocol.
I was confusing Nec1-X2 with Necx1 and Necx2, because I'd never seen all three names together.
So I loaded up my Atlas and took a look at the Aud/0872 signal with my IR-Widget.
A Nec1 sends:
Nec, ditto, ditto, ditto, ditto.....
A Nec2 sends:
Nec, Nec, Nec, Nec, Nec.......
A Nec1-X2:
Nec, Nec, ditto, ditto, ditto, ditto.
A Necx1 is a signal that follows the Nec1 rules except the lead-in timing pair is smaller and ditto timings rules are different.
A Necx2 is a signal that folllows the Nec2 rules except the lead-in timing pair is smaller. _________________ Remember to provide feedback to let us know how the problem was solved and share your upgrades.
Tip: When creating an upgrade, always include ALL functions from the oem remote, even if you never plan on assigning them to a button. Complete function lists makes an upgrade more helpful to others.
