Simple page with all 16 house and device codes. Works just like the old 6-in-1 remote: 1) Press the desired house code; 2) Press the desired device number; 3) Press the desired function (On, Off, Dim, etc.). Once steps 1 and 2 are done, you can just press the function buttons to continue controlling that same device, until a different house code/device is selected. From here, the individual X10 codes can be lifted and used within a macro to tie the desired function to a single soft button.

I used to use a Pronto RU940, but now use the MX-3000. I've been programming it for the last week or two and got round to the home automation side of things. I just got the IR7243AH and found the X10 codes available didn't work for me. I uploaded the codes for the Pronto and then " learned them" to the MX and thought that maybe someone else might use them. I have tested them with my setup, but, these may not work with yours.
