Did you ever manage to hook up the Foard Compact bridge? was it an X10/UPB bridge? in particular, was it this one?
Yes, This is the bridge that I installed in a clients home. After a lot of discussion with the factory I was able to get it working. It works great! It receives x10 or UPB and you can assign multiple commands to any received code. The unit you referenced has more bells and wistles and wants to be a HA controller; therefore it is somewhat complicated to use. It has x10 and UPB logs so you can follow the signals of both x10 and UPB. You can keep it connected to a computer and to the x10 with a TW523 and a UPB PIM.
I have it receiving x10 from touch pads (that send a lighting scene to PCS Scenemaster x10 switches) and sending UPB signals as well as other x10 to devices that can not receive multiple codes. This is building macros from a single x10 signal. I also have it receiving UPB links from a SA Timer/Scheduler to operate existing X10 devices by timer, such as 220v pool pump switches.
Again the reason I went with the Foard is that it supports UPB Links where the other brand did not at the time.(I don't know if that is still true)
When I set it up I had the feeling from the factory that there were very few out in use and they were interrested in helping me get it working good. The spent many hours, yes hours, with me on the phone working out bugs. The tech and the owner of the company (Mr. Foard) worked with me to get it right.
When programming it the logic was a little hard to grasp. I thought (and told them) that it did not need to be so complicated. (For instance they used an engineering term that ment nothing to me but ment a simple process, sorry I do not remember what the word was, but at the time it was odd.
I would recommend it with a warning that it might require
more than a little tech support from Foard. But they were very good to work with.
