JP1 Remotes

Thanks for the compliments Graham and Rob. I'm glad you think its worthy of sticky status.

PcRider, the thing to do when you run into trouble is to ask for help. My initial response to you was a how to ask for help post. and I'll add that to the IRHelp file like you suggested. You can struggle ...

I have now gone through and updated the IR Help file.

I've tried to make it more readable and would like to know what parts of the document are still too muddled to be understandable.

IR Help

Since this is a document for newbies, newbie feedback is valuable.

Bearing in mind that you asked ...

I'll read it tonight!

I have been trying to merge the learned signals I got from my Magnavox digital converter box into the file I downloaded before I started doing the learning.
Right now I have 3 of my devices in one IR file, and the learned signals in another IR file.

IR says the learned signals are emerson device ...

The device is an infrared LED. Although it is primarily an emitter, it will also function as a receiver and give a small electrical signal when properly biased and illuminated by another infrared LED. So it is, as you say, both a transmitter and a detector in one package.

The Radio Shack part ...

If you understand how semiconductors work, it'd be clear that applying a fixed voltage directly to an LED, is going to result in disaster. A quick examination of the VI curve for an LED, would show that the current rises extremely quickly as the voltage is increased. That's why for applications ...

I have been messing with an older URC8810 remote trying to install codes for all my stuff which meant re-learning JP1.
Well at one point it was not doing anything to turn on the tv, and I knew the IR light should be picked up by my IR security cameras.

When it wasn't there I wondered is it the ...
