I have a situation in our home theater where the connections from the equipment closet to TV look like:


Equipment --> closet wall connection --> wire in the walls -- > theater wall connection --> TV


Now, I've got a Cat-5 jack behind the TV that ends up in the closet as a jack there as well. This has been set aside for a Xantech IR system.


I've got the whole connecting block/power/receiver/emitter concept down, but what I'm wondering is this: can I take a cat-5 connector, crimp the end of the 3-wire receiver cord and make a "Cat-5 receiver" that then plugs into the jack behind the TV and have the IR signal transmitted over the cat-5 into the closet? On the closet end, I was thinking I could do the opposite there -- make a mini-plug wire with a cat-5 connection on it and plug it into the block that's in the closet.


Will this work? I really don't want to have to have one long continuous cat-5 strand that goes from the closet, into the wall and out by the TV with no clean, cut off connection jacks.


If I can't do this, is splicing the 3-wire as easy as just picking 3 wires in the cat-5, splicing the receiver into it and just keeping that same cat-5 wiring configuration on the block end in the closet and screwing it down in the terminals?


Thanks in advance!

The reason I asked is that someone told me that the power didn't always like to be going through the cat-5 connectors and such and that you could get inconsistent results.


Dave, do you guys use Xantech at AVX? If so, could you sell me the equipment direct so I don't have to mail-order it?

Having a junction-less wire is better in some ways but remember that this is a "phone" connection and that it self has about 70-90V when ringing. Much more than 12V from Xantech.


PM me with you list !

Re IR over CAT 5, tie all 4 solid conductors together and tie all 4 striped (white) conductors together (ground). Use these two pairs for your IR. Xantech recommends tieing a 470 ohm resistor across the two pairs shunting the IR signal to ground.

Okay, now I'm confused -- the receiver is 3-wire; where's the other wire come into play in this scenario?


Can't one of the 8 wires each go to one of the 3 wires of the Dinkylink?

the 3rd wire provides power to the receiver(s), you can do without it in "phantom-mode" but you would have to supply local power which is not always acceptable. Yes, you can simply have 3 wires connected to the dinky link, but I haven't tried it over long distances (I've done 50 feet successfully).


Perhaps some one else can verify if this works well over longer distances.




good luck

Well, you could gang the wires together in pairs. Use the blue & white/blue as one, orange & white/orange as another, etc. That gives you four conductors for your IR connection.
