I just set up my MSC-400 with my MX-950 and it works great. The problem is that I have 2 MX-800's and 1 MX-850 around the house that I want to use to control my equipment with as well. I don't care that I can't do Macro's with the MX-800/850's through the MSC-400. I was wondering if I could send signals through the RFX-250 to the msc-400 to the equipment with the MX-800 remotes and how, or do I need to also set up my RFM-200 with additional flashers to my componants.
Thanks,

I think you'd need to set up your RFM with flashers. I don't think Either the 800 or the 850 will communicate with the RFX250.

The 800/850 will work with the RFX-250 but only in conjunction with an MRF-300 or 350, not with the MSC-400.

Is it a limitation of the MSC-400 that won't pass along the signals? If I were to hook up an rfx-150 instead of the 250 would that work?
Right now I have things working ok by just hooking up an extra flasher from my mrf-200 to each componant that I want to control, but this is redundant and harder to keep the wires looking neat.
If this is the case, I don't understand why URC is keeping the MX-850 as part of their Complete Control Suite because it requires redundancy when using the other remotes in the suite and the MSC-400.

It's the MSC-400 to my knowledge. See Eric Johnson's post here.
