I Found two CCF for Adcom devices files in which NEC:26.232:84 is the discrete ON command:
[Link: remotecentral.com][Link: remotecentral.com]Both of those are commented as being "NEC2" but both are generated signals that lack the part that distinguishes NEC1 from NEC2.
Anyway, if those work, I guess you'll find it easier to take signals from those CCF files than to generate other versions with MakeHex.
