Hey, guys,
I have an installation where the displays are so far from the A/V equipment that the Pronto RF extender does not reliably receive the RF signal (Pronto TSU6000). Miraculously, everything else works great. I want to put the receiver over near one of the plasmas so it will definitely receive signal.

I have run into trouble trying to use the output of an RF extender with other wired equipment's IR inputs. Does anybody know what to put between a remote extender's output jack and the IR input of a Xantech device so it will work?

So far I know I can slap a dinky link onto the front of the RF receiver, but that sure seems like a dumb way to do it. Expensive, too, compared to just running a wire.

If someone does not know how to do this, but can give me a technical description of the output circuit of the remote extender, I can engineer a circuit to do what is needed.

Anybody?
A good answer is easier with a clear question giving the make and model of everything.

Ernie,

It's been a while since I've used the pronto RF receiver, but the last one I used had 4 3.5 mini outputs on it. In theory, I would think you could simply solder a couple of mono mini plugs on either end of a shielded cable, extending the output phase (which is now flashing IR) of the Pronto RF unit, and plug into your Xantech block's IR input...

I don't know why the components aren't responding acuratetly, that's perplexing to me....they should be essentially the same codes at the same intesity and frequency, as the remotes that originally taught them...

Let me know how it turns out!

Put a 470Ohm resistor across the Signal(IR IN) and Ground on the Xantech input.

This is documented in the instructions that come with the 789-44 for long distance Sheiled cable runs...
