OK Guy, success!
I captured IR onto a scope off the original remote and got this for the power button:
0x13D15 or in binary:
MSB-LSB
Sub-Dev Dev Code
00010011 11010 0010101
LSB transmits first
That is 26.19 code 21 (in decimal)
Using the complicated rules from this link:
[Link: remotecentral.com]I come up with:
037A0200001500000083
And after programming that into the AX1400 it successfully toggles power.
The remaining codes are probably as you gave above but with 037A02 in the highest digits.
