This thing sure doesn't cost much to build. I didn't have the RS part #s, so ordered from Mouser. I ordered 5 of everything and the order still only came to .80. Then the postage was 4.50.

Now, if I get around to build it all will be well.

Is there really any need to test it before hooking it up? I usually just shove the throttles ahead and assume the runway is long enough.

With a 2.2k resistor being the first thing that the Ocelot "sees", you can't really blow anything, so prior testing is not an absolute must, but you might still want to do a simple sanity check just to avoid any frustrations if it doesn't work the first time. Its up to you.

Isn't that half the fun of this wonderful hobby of ours?

To me personally, building stuff is 80% of the fun! I'm more of a builder then a user.

FYI,

I reversed the Diode the first time around!
So, yes I want to test it first!!

Mine is done and I tested. Ready for the install:)

But, I need to squeeze the MP3 server and the monitor into my stereo closet.

Maybe this weekend!

Thanks all,

FYI,

Project was a success! Circuit works great.
I am now using X10 wall transmitters to control Stereo volume, tuner station, etc.

Only gripe is I can't find an "Elegant" X10 keypad (My wifes words ).

I found that Leviton makes a custom labeling kit for their new keypads, so maybe...

I will work on a link to my project web page and post it SOON!

Thanks,

Below is a link to my Ocelot/IRA-2/Girder system. I thought others would like more info on how to use X10 and the Ocelot to automate a music system, with an MP3 computer connected.

http://toddjreed.home.comcast.net/ToddsHAproject.pdf

From my wall keypads I can now control my stereo system, and start MP3 playlists on the computer!

Many thanks to other members for the many tips and interface circuit to interface the Xantech IR system.

Amazingly enough, I got my Ocelot to Xantech circuit completed according to the above diagram.

I guess it works. No smoke, IR emitters blink brighter than before, nothing has stopped working.

I am expanding my system!

Can I add a Leopard IR output to the 5vdc side on the same board? Or, do I need to build another board??

Thanks

Do you mean that you want to mix the outputs of both your original Ocelot and now your new slave Leopard together and send them to your Xantech system?

That answer to that is: maybe... The usual issue with ADI controllers is that they don't have a hardwired common ground between them. The chances of success would be good if the two controllers use seperate, floating power supplies. If the new Leopard is used with the wall wart that comes with it and nothing else is sharing that wall wart (and nothing should, because there is only enough power for the Leopard) then the two units will establish a common ground through the IR out's ground connection. To mix two IR outs together, you would need to add isolation diodes to safely isolate the two IR out signals. Going back to my original ASCII diagram, it would look like this:

[CODE]
|------------|----------------o to Xantech +12v
| |
> |
< 1k /
> 1k |v
Ocelot |--mwmw----| 2N3906 (PNP)
IR out / |
(tip) |/ --mwmw---|>|----o to Xantech input
o-|>|-+-mwmw----| 2N3904 | 470 1N914
| 2.2k |^ (NPN) |
| >
o-|>|-+ | < 1k
Leo IR out(tip) | >
| |
diodes = 1N914 | |
| |
o------------------|-----------|----------------o to Xantech common
Ocelot and Leo
IR out (ring)


note: the ^ and v designate the transistor's emitters (ascii art!)[/CODE]

I built the circuit using a 2N4401 on the 5v side and a 2N3906 on the 12v side. My first surprise was that it worked the firt time I plugged it into my Ocelot.

My second surprise was that sometime the second day the Ocelot locks up, both IR and X10. If I unlug the IR Amp, things start working again. I have double checked eveything in the circuit and I beleive I have it all correct.

Any idea what may be causing this?

I have a hard time seeing how the Ocelot's IR output could cause it to lock up, unless you are having some kind of general power problem caused by mismatched grounds or something like that. Is the Ocelot powered alone by its supplied wall wart, or are you sharing a power source somewhere between the Ocelot, amplifier circuit and the Xantech system? Its ok to have the amplifier circuit and Xantech system share the same 12 volt power supply.

Thanks Guy, mismatched grounds was causing my problem. I replaced an IR Blaster with the Xantech, I disconnected the positive from the power supply to the blaster but not the ground.

Okay, one more variation!!

Can I run the Ocelot IR in and a Russound A-Bus emitter in to this ciruit? Similar to the Leopard In explaination...

The Russound emitter is a two wire, powered by the A-Bus hub.

IF the Russound emitter is also a positive when transmitting signal, then it should be possible. If you are thinking of connecting both an Ocelot and a Russound emitter at the same time, then isolation diodes should be used between the signal lines. This means placing a signal diode (eg: 1N914) in series between the jack and the 2.2k input resistor. The anode would go to the input jack and the cathode to the 2.2k resistor. Thus the cathodes of the two diodes (one per input) would meet at the resistor.

The Russound is +12v, so I assume I could use the 1N914 diode and connect to the Xantech "input" and "ground" on the right hand side of the diagram? If I connect the Leopard as well, then I have ADI coming in at 5v, amp'd to 12v, then add the ABUS IR, then out to Xantech hub!

Any issue with grounds, coming from the different power supplies?

ABUS
Xantech
Ocelot
Leopard

If they're floating power supplies (wall wart with only two prongs) then there should be no problem with grounds.

To all,

I've built the circuit to connect the Ocelot and Xantech devices together to the best of my ability, but unfortunately, nothing I've tried to test it appears to work properly. Please bear in mind that I am a novice with no "official" training in electronics or schematic diagrams, just what I've researched on the web and in books. There are probably some basic concepts that I haven't mastered yet, so be kind.

Anyway, I had fun building the circuit, but haven't been able to make it work despite checking the component layout multiple times and testing for any shorts between connections. Could someone please explain a few tests I can perform (in plain English, please) to make sure I haven't done something obviously wrong on this circuit. I would be glad to post pictures if would help.

Thanks in advance,

Chris
