I went looking for your product "4110" could not find it. But this is what I encountered, for some unknown reason to me the rfx6000 does take a different set of ir codes for the x-10 coversion to work.
I got my codes from
www.laser.com because they make or distribute the ir543ah. The codes only work with the rfx6000.
I did have some problems with all lights off and all lights on because of all the old x10 equipment I have. Powerhouse, Radioshack Plug n power, etc. so I experiemented with the default codesets supplied with my pronto tsu7000 and found that the preset Philips 0279 worked.
Anyway, contact smarthome for the codes to work with your device. They have excellent technical help.
You can look at the structure for my pcf, but you will need to run it on the latest PPENG software.
