To hopefully save myself a bunch of soldering onto a mx-900 key pad, has anyone decoded the rfx-250 output that is sent to the msc-400?

I have gotten rs-232 input to the msc-400 to work via a rather extraordanay rube goldberg, but I can't send them fast enough. If someone has the spec, I will knock out the interface in a few hours.

What are you trying to do with the 900? I think you are trying to turn a contact into a rf code or button press on the 900.

Yep.

It would be much nicer to just to figure out what is going on the data line from the rfx-200 to the msc-400. And then just send a code to the msc-400 to execute a smart macro. If I just had a few it would be easy, but I have a lot (>1000) and they need to be executed quickly ( < 1 sec) My rube goldberg contraption takes about 2,5 sec and can't do this many.
