Hey everyone! I have an IR reader, but it spits out a result that is not in hex format. I'm still a noob when it comes to understanding hex, so I thought I'd throw this out for the group:

That is the standard Onkyo power toggle signal. There are lots of CCF files here at RC including that signal in Pronto Hex.

What are you trying to do?

You can create clean Pronto Hex for all the Onkyo signals using MakeHex.
[Link: john.fine.home.comcast.net]
Be sure to read the readme file before running it.

The protocol for Onkyo is NEC1. For some commands, the device number is 210.108, for others 210.109 (so for a full set you need to run MakeHex twice).
The signal you posted above is device 210.109, function 4.

The section with all the 01:02 encodes the information part of the signal (the 00, 03, 04, 05, 06, and the other sections are all structural info that tells you it is NEC1 protocol).

The first 8 of those 01:02 give the device number. 01 represents a 0 bit, and 02 represents a 1 bit and the sequence is backwards, so
:01 :02 :01 :01 :02 :01 :02 :02 represents binary 11010010 which is decimal 210.
The next 8 are the subdevice number.
:02 :01 :02 :02 :01 :02 :02 :01 represents binary 01101101 which is decimal 109.
The next 8 are the function number.
:01 :01 :02 :01 :01 :01 :01 :01 represents binary 00000100 which is decimal 4.
