How do I connect Global Cache GC-100 with IR-100 connecting block and URC MRF-260 RF/IR receiver?

I plan on mixing the following components together in an IR system:
  • Global Cache GC-100: 12 to 85V DC@500mA (wall power adapter included)
  • Buffalo IR-100 Connecting Block: DV9-500: Unregulated 9Vdc @ up to 500mA (Actually provides ~12Vdc when lightly loaded by a typical basic IR system)
  • Universal Remote Control MRF-260 RF/IR receiver: 9V DC (AC Adapter included)
  • Tivo IR output over wire: I think this is just SIG and GND and no PWR.
But an am weary about the compatibility between them and any special considerations.

Since all the components have power I assume I don't need to use the PWR conductor and I just need SIG and GND when connecting the IR cables. But is the varying voltage between each unit going to cause a problem? it looks like the GC-100 uses 12VDC, the IR-100 uses ~12VDC, and the MRF-260 uses 9VDC... according to the product websites.

Thanks,
Johnny
 
I've done Xantech with Tivo (with a zoned setup and eyes in the various bedrooms). I have a global cache setup but have not installed it. If you have multiple Tivo's, you can assign ID's to them with the remotes so they can both receive the same signals but it will know which one you are trying to control. If you ever use a Harmony remote, call them to configure, they do not allow this via the website and need to do it for you. Check into how to do ID's for your Tivo for your remote if this situation applies.

I think what you need to worry about there is that the Buffalo is equivalent to the Xantech in power or the way IR is done, which is different from the global cache. I know you need adapters to go xantech -> global cache and back.

See this page:
Global Cache Xantech Install

It has been a long time since I looked at this but I think you might be right to question the compatibility.

You may want to drop Buffalo Electronics a line, as if they are equivalent to Xantech then you probably need the adapters for Xantech, if not it may work as is. It might also be worth it to contact GC as they may have seen this before and may give you a quick response.

Contact Buffalo Electronics

Unfortunately I don't have anything definitive for you, but I hope this helps.
