What's the easiest, most reliable way to split IR signals coming out of RFX9400?
RFX9400 has 4 outputs, I need 6.

I don't need all of them to be routed.

Dual emitter IR flashers won't get me there.

Two of them for example would run to 2 remotely located TVs, a Sony and a LG.

Do I run the cable out of the back jack and just split the feeds with beanies?

Do I take the 'feed' and run it to a connecting block with power, like the XANTECH CB20, or the likes of one?

Do we have connecting blocks available with both screw terminals and 3.5mm jacks?

Note: also posted in the CI forum.

Thanks,

Used to wire them (splice) in series, found that parallel works better with our current systems.

Use the connecting block with power.

Works like a charm.

We use these all the time when the universal remote or rti runs out of emitters.

Probably doesn't need to be a powered connecting block.  Power usually just goes to the +12v terminal to power a sensor.  He would probably only need an amplified connecting block if he's really pushing some distance.  A 789-44 or ECB-5 with no power connected would probably work fine.

Speakercraft used to have a IR splitter cable (complete with diode isolation). Part number was SAC-1.0.

Not sure if this is still available or not.

This would be more helpful if you'd mention what your current systems are.

An IR distribution block is simply several of these:
IR signal ------ 470 ohm resistor ------ IR out to emitter +
IR signal ground-------------------------IR emitter -

The resistors limit the current to each LED and ensure that the LEDs all turn on by isolating them from each other.

If you want to take an output and double it up, take the plus and add this:
plus------------100 ohm resistor---------------LED 1 +
plus------------100 ohm resisotr---------------LED 2 +

That will only give you one additional output, so do that with two outputs. Don't split one output more than once, just to stay on the conservative side.

I've used a Xantech 789-44 on an earlier model of Marantz RF receiver and it worked well.

Only use the split outputs on equipment near the receiver. Again, be conservative: don't send the modified signal to the more difficult situation.

It would seem that a single 3.5 mm mono male to two 3.5 mm mono female would be internally wired in parallel and thus able to act as a splitter for ir. Is this correct?

I hate splicing IR emitters to get two emitters out of one port and sometimes I don't have a dual emitter handy...

Still available, but it's not what we need here. SAC-1.0 would be more useful to use the same emitter with two different IR inputs.

In this situation EMX-1.0 would be more useful. Works fine.

However, the resistor in series with an LED brings the signal voltage down to whatever voltage it takes to turn on the LED. If LED A comes on at a slightly higher voltage than LED B, it won't turn on because LED B will bring the voltage down to its turn-on level.


Yeah, that's too bad, but it has to be done. Incidentally, a dual emitter is/are two emitters in series, not in parallel, because of what I said above.

 i've split outputs on Nevo NevoConnects up to 3 times in parallel with no issues.  We use Niles emitters if that makes any difference.

I used to do this with Crestron ST-CP's using mono Y adapters from radio shack.

If they come from the sam manufacturing batch your chances are pretty good that paralleling will work. I'm suggesting going past "pretty likely" as your performance goal. When, one day, you find that it doesn't work, you'll go nuts trying to figure it out; thus you should do it the way that will work every time, which is series LEDs or a resistor in series with each LED.

OK, what am I missing?

Port 1: Sony TV
Port 2: LG TV
Port 3: Dual Emitter Device 3 and 4
Port 4: Dual Emitter Device 5 and 6

Nothing. I think this puzzle has been solved.
