I currently have a USB-UIRT connected to a Xantech system. My goal is to use a PC to blast all my commands. I'm not using the IR receiver, basically im just using it as a wired system.


Anyways, my problem is that the system doesn't work very well. Some things work, but most don't. My 'heavy' equipment doesn't work (receiver, cable box, tv, e.g.). What does work is my projector and drapes.


Everything works fine when using a Xantech receiver, so im fairly certain the problem lies somewhere between the Xantech-USB-UIRT connection. Currently, they are both connected via a 3.5m stereo cable. I have searched around quite a bit on the internet and think I know the problem. It seems that these two products operate on different voltage levels (12v for the Xantech, 5v for the USB-UIRT. I know nothing of electronics so I don't know if the voltage difference can cause that problem, but at this point it's my only guess.


In all my searching, I have come across a product that seems to work for most people:
http://www.smarthome.com/8175/IR-Lin...Systems/p.aspx


The problem is that this product is discontinued.


I don't even know what that does nor do I have the technical knowledge to make my own circuit board. Can anybody help point me to an alternative product to interface my Xantech with my USB-UIRT? Thanks.

Anybody?

Sorry, but all I can say is that I have an IRLinc and everything works flawless.

There is another company that makes them, but I don't remember who that was.

I do know that they're sold at ~$50 compared to the ~$20 that I got mine for.

Check up with global cache and russound; it very well may have been one of them.

Thanks for the answer, the only thing I could find even close was this:

I don't even know if it will work. The guys tell me they need a schematic of the USB-UIRT to test it out and I have gotten no help from UIRT either.


Is there anybody familiar with electronics who could build such a device? Of course you would be paid. I found what seems to be a schematic for an alternative here:

The majority of my system unfortunately will not work at all until this is resolved

The USB-UIRT has a standard 1/8" IR stereo transmitter plug configuration. It has 2 "channels" of IR output available on the plug.


The GC-100 device discussed has a 3.5mm jack for IR transmitters. I'd assume it is a mono plug.


If the above is true, I'd expect that device you found will work with a little work.


This shows you how to connect the mono plug from a IR transmitter to one of the USB-UIRT output channels. You should be able to plug that adapter into the splitter the same way.

Here is info for connecting IR transmitters to the USB-UIRT. The guys selling the GC-CGX should be able to use this to tell you if their unit will work using the above.

Thanks, I ordered the device and will try it out. I am only using one zone - I was under the impression that the UIRT blasted to both zones by default. Would I still need to split it?

You should be Ok as long as the mono plug makes a good connection into the stereo socket. You might have an issue with the connection but probably not.

If I recall, the one I have only has a mono output as well.

I needed zones, so I used a stereo to L/R 3.5mm splitter with one output for the Xantech block via IRLinc and the other for a dual-head emitter.

Yes, the unit will blast to all 3 zones by default, but with Girder that I'm using I can control all of that.

 

[golden3159]

Well, looks like I just blew another $40. The GC-GCX doesn't work AT ALL. At least without it, some components worked.


Does anybody have ANY ideas on what I can do? This is so frustrating! I have already designed all the menu's and interfaces but this is the last problem.


An IR receiver connected to the Xantech works with no problems - all components work fine. Same with connecting to the UIRT.


So the problem is 100% between interfacing the Xantech and the UIRT. IR Linc is the only thing that seems to work and now that nobody makes it anymore, it looks like im screwed.

 

[golden3159]

Last plea for help, does anybody have any ideas or perhaps a place to where I can buy an IRLinc?

 

[JoshDorhyke]

Is the GC-100 IR side of that converter a 2-wire connection? If so, maybe you have to swap the leads. In other words, the polarity is backwards.


If that converter is a good unit, the Xantech IR side of it would be OK as is.

[JoshDorhyke]

Oh yeah, what did "the guys" who told you that with a schematic they could help say? The info I posted basically tells you how to connect to the USB-UIRT and how it's outputs work.

Sorry for reopening a dead thread but I came across this as I was searching for answers to another problem and wanted document a working solution for Xantech and the USB-UIRT in case anyone else was searching.


1) Connect the USB-URT to a Xantech CB12 connecting Block Via 3.5mm Stereo cable (this can be skipped if you strip the 3.5mm cable but it makes it a lot easier). There are three screws on the CB12 Labeled "V","G" and "S". I am using the CB12 to split the 2 ir outputs from the 3.5mm output jack on the USB-UIRT. "V" is now Ground, "G" is now the "RIGHT" output of the USB-UIRT, and "S" is the "LEFT" output of the USB-UIRT. Do not connect a power adapter to the CB12, it is only used to split the 3 wires from the 3.5mm cable.


2) You are going to need and amplified Xantech connecting block (ie Xantech 791-44). In order to connect the "RIGHT" output of the USB-UIRT" to a Xantech connecting block you will need to wire the screw labeled "G" on the CB12 to the "IR IN" on the 7911-44 and the screw labeled "V" on the CB12 to the "GND" on the 791-44. Do not connect anything from the CB12 (or USB-UIRT) to the "+12 VDC" or "STATUS" on the 791-44. The 791-44 will need to be powered by a power adapter (ie 781ERGPS) for IR to be strong enough to reach the equipment. The "LEFT" Side of the USB-UIRT can be wired to another 791-44 by connecting the "S" on the CB12 to the "IR IN" of the 791-44 and the "V" on the CB12 to the "GND" on the 791-44.


Hope this helps
