Are you setting the !Output to 'Hex' instead of 'Decimal' or 'Both'?

This is what you get when sent to Hex,

Device Code: 15 Function: 00
0000 0073 0000 000A 0020 0020 0040 0040 0040 0040 0040 0040 0040 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0CC5

15 in hex is 21 in decimal. When the !Output file is set 'Hex' the Device Code and Function no. are in hex instead of decimal but still give the same Pronto Hex String (code).

When you enter the Device no. (Main a) and or the Sub Device (Sub b) these are always in decimal. IRTools DecodeIR results are show in decimal. 'OBC' is the Function no. in decimal.
