How do you do this? I've searched all over the forums and the file library and can't seem to find anything on doing this (other then to load it into the PRONTO - my problem is my PRONTO is dead and I'm trying to take the programming to put into another remote). So I need to take the 5000 ... number and convert it into real HEX. Any help please? Thanks,
Shawn

Unless the new remote is a Pronto-based remote using the same hex notation, you are SOL unless you find a utility in a location such as the JP1 forum on Yahoo where John Fine and those wonderful folks support other remotes.

RC5 is already hex - it just starts with 5000 instead of 00000.

What other remote are you going to load it in to that does not understand RC5 hex?

There are a few other remotes that understand Pronto Hex, but don't understand the ones that start with 5000, just the ones that start with 0000.

For those you can use the MakeHex program to generate the 0000 version of RC5.

The 0000 version of RC5 doesn't encode the "toggle bit" of the RC5 protocol, so you may end up with signals where each one works following any different one, but no signal works again immediately following itself. There are a variety of tricky work arounds for that. But first see how far you get without worrying about that detail.

OK - I'm confused how to use your utility John - I have, for example, a code: 5000 0072 0000 0001 0000 0038 - how do I put this into your .irp file to have it convert it? This particular code should be a toggle for a Magnavox TV (if that helps). It should be a RC5 code. So I'm confused as to where I would get DEVICE= and FUNCTION= - then also confused as to where I would put the RC5 code that I DO have (above)? Thanks John!

You are correct - but I'm finding that more and more vendors are accepting the Pronto HEX codes (Universal Remote does (sorta) - and now all the Control4 stuff standardizes on it).

to that does not understand RC5 hex?

In this case - a Control4 system which ONLY uses straight HEX (Pronto?).

In the code you have the "5000 0072 0000 0001" just means the signal is RC5. The next 0000 is the device number, so in the .irp file you need to make sure you have DEVICE=0.

The 0038 is the function number, but it is in hex. MakeHex's input for function numbers is in decimal, and by default its output of function numbers is also decimal. See its readme for getting function output in hex, or translate the function numbers you want to decimal before using MakeHex.

0038 hex is 56 decimal.

Assuming you want several functions translated, it's easiest to leave the full range specified in the Function line of the .irp, then find the ones you want in the .hex file.

I see! Ok - that's good to know! Thanks for the info John - I should have enough here to go and play with your utilitiy and get a whole set of codes!!! :) Is there somewhere I can get what the standard RC5 functions are? In this example this was Function 56 which was some SURF or something I think? Just curious. Thanks again!
