Re: IR Emitter for Comfort

Hi Dean
I dont *think* the Xantech emitters would have current limiting resistors
built in as the value would depend on the voltage being used on the
transmitter output......

Response on the Comfort list was that I needed to make sure any IR Led had
the appropriate current limiting resistor.

Can anyone confirm if the Xantech emitters have the resisitor in the
emitter
or not ?

Thanks

The comfort manual suggests I can simply add an IR LED to a comfort ouput
to
allow comfort to transmit pre-learnt IR codes.

Anyone done this and comment how well it works and/or got a Farnell/Maplin
part no for a suitable LED.

Can I just use one of the emitters available for Xantech etc. (like these

The application I have in mind would only need to operate 1 device in
node0 - so no need for high power blasters or anything.
