Creating IR Hex Code

cvarner

I have a system that has several Vizio displays (VF552XVT). The available codes in the IR database and the actual remote only have power/input toggle commands. Because I need discrete functions, I called contacted Vizio tech support, and received a file with some of the information below. My question is: Is this enough information to assemble into a working IR hex string?

We use NEC protocol with address 04FB for all of our TVs (except the really old ones, like P4).

Key Label Code
POWER 08
PWR OFF 25
PWR ON 2A
RGB 98
HDMI 1 81
HDMI 2 82
COMP1 71
COMP2 72

Here is an IR hex creation program. It has been ages since I used it so I won't be able to answer any questions you have.

Here'sa link to help explain the NEC IR format:

There should be a readme.txt that explains how to use the makehex program in Tony's zip file.
