You can actually get all of the "ir hex commands" from Denon's website here...

[Link: usa.denon.com])

Move down to the middle of the page & select the docs tab. Then download "Denon Master(1.87 MB)".

All of these commands can then be imported (one at a time) into the URC programming software using the hex editor. The instructions are in the help section of the programming software.

URC is usually pretty good about having all of the correct commands in the database, but sometimes they are incorrect &/or they are missing some commands. You can usually find most of the commands from older models by pointing and shooting the commands at the receiver. Keep in mind the URC has to add thousands of commands to their database and sometimes that takes time. I am not a Denon dealer, but I did program the same receiver using RS232 a few months ago and only a handful of the codes were incorrect or missing.

Sometimes programming a remote actually requires a little bit of work...
