[QUOTE="shumifan50, post: 629131, member: 265778"] I agree that is most likely a bad clone device. IR remotes are sensitive to the carrier frequency of the transmitter/receiver being matched. Some devices, like the harmony remotes, cover many carrier frequencies. Cheaper devices may not. Then on top of it there are different ways to implement the protocol and then there are many different protocols, RC5 being the popular one for hobby projects. Again the more expensive remotes might support these while the cheaper ones won't. And last but not least there are differences in pulse timing. A all-in-one remote has to handle all of these conditions, which is why most support only a device list. The trainable ones have to be a lot more clever and tolerant of variations - and therefore much more expensive to implement even though most of it is now done on software on the remote. Have a look at this url to get an idea of how remotes work. _http://www.sixca.com/eng/articles/remote/index.html [/QUOTE]
