Extra IR blasters for 9910 base ?

Using a male-to-male connector to connect the base to the connecting block should work just fine.

WOW, that would be great
Will have to pick it up from the cottage and test next week !

Thanks

well, I did more checking in to this but the
Xanteh input is 3 wires :

How to connect ?

As long as your are providing power through the 12VDC connector, your should be able to connect the IR cable from the base unit to the IR IN and GND pins.

It's still probably workable. The third wire will be to supply power to their receiver which you don't need. (power , ground , data) Use a stereo jack on that end of your jumper with the power pin left open. The 9910's normal blaster output jack may or may not have enough amplitude to drive the extender as originally wired (accross only one diode - approx 2V DC) Going from the first LED's input to the last LED's ground might give enough drive (about 5 Volts Peak to Peak) to run the extender. Otherwise you would have to change the bias resistors inside the extender to trigger on lower input voltages. Just make sure you do not share a power supply between the two units or else you will have to worry about grounding problems.

OK, Thanks...I'll try that

I'm happy to report that it works great !

NOW, project #2
Can I connect my Pioneer receiver IR control to the Xantech box
and get the same result ? ( I like to avoid gluing the emitor
on the receiver's IR port)

Well, I spoke to soon

When I leave the Xantech box connected the 9910 receiver is going crazy by it self ( sending IR by it self) Looks like grounding problem since when I touch the end of the receiver's antenna it stops.
Is there any way to eliminate this interference ?

Thanks

Ok, got that problem fixed by attachin 150 ohm resistor on the Xantech IR input. Works great now.

Back to the possibility to fead my pioneer receiver IR signal using
the IR jack on the VSX1014 - IS THIS POSSIBLE ?

I don't know if I (we?) have enough info to get started. I am not familiar with your Pioneer device. Are you trying to send the IR signal to a receiver using a wire rether than an IR led? The IR pickup device (in the receiver) usually filters out the carrier wave (that's the 40 khz - for example - frequency that you see on learned signal details) so it would be difficult to hard-wire it. A local Home Theater Dealer runs the small emitters inside the case and puts it next to the pickup behind the front cabinet. You can't see it from the outside. (that's why they are so small)

Yes, I like to connect the receiver using wire .
There is IR in and IR out socket on the back panel.
Xantech is making connecting block that makes this possible.
I just like to avoid spending the $$ if there is simple option to do that

The problem is that I don't know what type of signal the input jack is looking for without scoping an input signal or examining a Pioneer service manual (don't have it and Pioneer manuals are poor anyway). If it is looking for a signal with carrier (apparently like the input on your first project) then plugging one of the led outputs into it might work (not likely and messing with a receiver could be a little more costly to repair than messing with an extender). Otherwise you need to filter out the carrier before sending it to the receiver (like Sony SIRCS signals). You could actually build a little photoisolator circuit to do it using one of the little output LEDs and a Pioneer IR receiver module. (those little pickups have some electronics inside besides the phototransistor. {LEDs are outputs while phototransistors are receivers}) Of course this would be functionally the same as putting the led in front of the pickup photosensor anyway.

There is another potential problem with wired hookup that has occurred on Sony sets and that is an override condition where the wired connection locks up the unit to all other inputs. The Zantech unit may make sure that only the Pioneer signals go to the Pioneer unit (and not elsewhere) while your only method available will be sending ALL the IR signals to the Pioneer on a potentially overriding wire connection.

I guess it would be cheaper to get the Xantech box ...

Thanks !

And one more question....
If I decide to put the IR emitter inside the AV equipment case
is there any chance that the emitter will blow the receiving phototransistor
with strong load of IR ?

Thanks

I don't know if your constant transmission problem could be related to this issue or not:

I am still trying to fix this problem on my unit. I am hoping that if I can resolve this problem the performace will be better. For some reason, the area of my house near my entertainment center has bad RF interference. Other areas do not....my bad luck I guess.
