Matt,
Barry Gordon has written what I think is considered the best documentation on how to decode Pronto hex and his examples are for Sony.
[Link: remotecentral.com]I now have a better idea regarding your equipment since you posted your two commands. Sony has three main IR protocols, known as Sony 12, 15, and 20 that describe the number of data bits. There is a 7 bit command (or function) followed by a device address that can be 5, 8 or 13 bits. The 13 bits is now considered to be a 5-bit device and an 8-bit sub-device.
Your two commands are Sony 20 device=26 sub-device=233 expressed as 26.233
The first command is 10 the second 11 (all in decimal).
The best library that I have seen for Sony IR commands is here:
[Link: anycities.com]If you click on 26.233 then you can see the known commands for that device code. To further complicate things Sony frequently uses multiple device codes for a single piece of equipment. This site referenced above has put together the multiple device codes that usually go together. In your case I did not see another device.
In order to generate pronto hex from this information, my favorite is John Fine's MakeHex:
[Link: remotecentral.com]One piece of useful information is that this version of MakeHex still uses the 13-bit device (not a device sub-device code) so to get from the 26.233 to the 13-bit number multiply the sub-device (233) by 32 and add that to the device number (26) for a total of 7482.
Barry Gordon also wrote a "hex generator" GenIRDB that also uses the 13-bit device numbers. If you know a lot about binary to decimal manipulation this conversion won't make sense until you read Barry's documentation.
Now after all this explanation, I didn't see any discrete input commands for this device and that means one of two things:
1. Some or all of them don't exist
2. They haven't been found yet.
So assume it is case 2 then you can generate all 128 commands with MakeHex and blast away. This is low risk with audio products but we always warn about doing this with TV/RPTV because there have been cases where people have hit service modes or factory resets requiring a service call.
Finally it is also possible that there is another device code that your system responds to – so you may want to analyze all commands on the OEM remote (by learning every command to your Pronto) for a second device code and try all 128 possibilities for that as well. John Fine wrote a program to decode Pronto ccf files called ccf2efc:
[Link: remotecentral.com] and ccf2efc can do that quickly rather than your having to decode them manually. If you do find new codes please post back the results.
Good luck,
-Jon
