I thought of this. How do you link one Vox to one microphone and another to another?

Is it possible to have different zones for Vox? For instance, I have a list of commands for my dedicated home theater. I would like a separate "zone" for the master bedroom where I have a TV there. I would like to separate the commands so the two zones can operate independently. Also, I do not want possible false commands in one area to effect another area of the home.

I use these microphones with my CCTV system at home and they are very sensitive. I have one in my den hooked up to Vox and it works great. The only down side is it requites 12VDC. It has a built in amplifier. And for $7 you can't beat it.

Just an update. I broke down and bought a new USB-UIRT and everything works fine now. The one I had before was about 10 years old so I guess it just died of old age. Thank you for the help!

I have cruised the UIRT forum for something relative, but not much help so far. Can you tell me what the error code is saying? I love Voxcommando, BTW. Once I saw how easy it was to program, I was off to the races.

I am getting the following error message when I attempt to send a "Pause" or "Mute" command using USB-UIRT:

"System.NullReferenceException: Object reference not set to an instance of an object.
     at vcPlugin.Plugin.do.SendCode(String p, Int32 repeat)"

I am worried that my USB-UIRT may not be working. System was working great for days, but suddenly I began getting this message every time Voxcommando tells the USB-UIRT to send IR codes. I am using the latest version of Voxcommando. I have tried this on two different computers. One is running Win 7 and the other Win 8. Both are having the same issue with the same USB-UIRT.
