The Wyrestorm matrix uses 5v IR instead of 12v, install the IR recievers that came with the matrix to the back of the unit and tape emitters from your control system to them to work around this. It makes the back of the matrix look ugly but it works. You will also have to use the Wyrestorm emitters at the display end as well or it will not work. I have an 8X16 HDBaseT working with an Elan g! using this method after trying what you tried.
