Well, I downloaded and installed IRScrutinizer. Using the hex codes it generates, I was able to make an IR file with IR Edit from AMX. I made two files. One IR file was created putting the 0 in the D field and the 0x80 in the S field. I made the other file reversing the order of 0 and 0x80.

I'll find out next week how it works as I'll be back on site then and can test.

Thanks, again, for the help. Hopefully, this will work!
