I have a JTD-Pro-4x8 4in 8out HDMI switch from J-Tech Digital. They supposedly gave me the IR Hex codes for the remote but it is only 3 numbers each. Looking at the IR hex editors and other codes there seems to be more to that. Can anyone help explain what I need to enter to create a valid hex file?

They said Button 1 = 00ff40 Button 2 = 00ff07 Button 3= 00ff09 Button 4= 00ff19
