Have a client with 2 TSU9600 remotes communicating thru RFX9400 to 2 DirecTV boxes, 1 port ready for future DVD/BD player, all using IRs. TVs are line-of-sight IR, no AVR.
Components are installed in a single rack, so no cable length of IR signal issues to deal with.

Somehow, one of the 9600 got washed.

Because client also uses the 9600 for HAI 2-way, I want to keep what he still has in-place, and only replace the damaged TSU9600 for the bedroom, where control of HAI it probably minimal.
I was thinking of setting him up with MX-450 or 980'ish type unit.
Are there connecting blocks that have doubled 4-in, and 4-out where I can double up the 4 inputs, to accept signal from RFX9400 and MRF-260?
I might be able to use Mac's (I think) idea from another thread from few weeks ago where he recommending using 3.5mm phono 2-1 splitter in reverse, if you think that that will work.

If you're going to feed IR emitters from two sources, look up the Xantech IR emitter (sorry, don't have part number) that has two mini plugs and one LED.

In the cable are two steering diodes that keep the output of each IR system from feeding into the output of the other IR system. You need these diodes for reliable results. That is, without the diodes, it might work.

It might not. It might work sometimes. It might stop.

You could connect the output of an IR system to a connecting block's IR Sensor inputs. This works with Xantech and RTI stuff. The other system's input has to be the bus, not an output meant for an LED.

Thanks guys. I should have checked Xantech catalog before posting.
Ernie and David must have been typing at same time as Greg; amazing how great minds think alike (Greg, Ernie and David; not I).

Update: Give credit where credit is due.

Would this work for you? I've read your post a few times and I'm not sure!

First paragraph: "Components are installed in a single rack ..."

Third paragraph: "... and only replace the damaged unit in the bedroom ..."

If the base stations are in the rack, maybe you meant "replace the damaged unit FOR the bedroom"??

Anyway, this Xantech piece should work (or, rather four of them) for what you want to do:

Or, you can make your own with some diodes.

I don't type fast enough!

Sorry, original post fixed.

I want to thank you for writing that just exactly the way you did. Usually someone will put in one of those accursed words, "just" or "simply." Frinstance:*


*If you haven't noticed, this is the new word I'm introducing to the language here. About ten years ago, when Adam Corolla (sp?) was jsut a guy phoning radio shows and putting on fake voices, a couple of local DJs decided to take two words, a**hole and jacka**, remove the offensive part, and create the new word jackhole. I've heard that word is now in some dictionaries! Maybe mine will be, too.
