I'm very new to this forum, I hope I posted in the right thread.
A friend of mine lost the little remote control for my LED Controller

I have to use it this Saturday, and after reasearching the internet, i found a website, where they reverse engineered the remote control and have some information about each buttons HEX code and the remotes protocol (http://blog.allgaiershops.com/2012/05/1 ... ed-remote/)
Is it possible to, somehow, send out these codes, using a home-made IR transmitter with my laptops audio output?
If the answer is yes, how can I convert the HEX codes to WAVE files?
I tried IrMaster, I've selected the Protocol as "nec1" (in the link above, they say, it's a NEC protocol remote, so i thought, that's the one to use), but after that, I don't know where to input the HEX numbers.
I don't really know what to put in the Device, Subdevice and OBC textboxes.
Thank you for reading this, and a million thanks if you can help me out with this!
