Weel it's not so easy to explain the whole figure but I'll try.

what i want to do is to use my crestron to send my ir code to an 433 Mhz Transmitter who talks with Nexa's 433 MHz series.

I've done this procedure witch the global cache IP2Ir and it worked with the same code, just transformed into their format.

I got the codes from a local swedish company who have discovered this, but the don't sell crestron so they are happy that it works with global cache.

That I coverted the hex format to global cache format and back again was just a way for me to mask sure it was a standard ccf format.
