Specifically, I need info on the coded pulses that are sent. I have tried to "see" the pulses by looking at the output of my remote control on the oscilloscope but all I get are a series of little spikes. This I would have assumed to be the coded pulses but I also found that the waveform on the screen was the same amplitude and frequency no matter what button I press on the IR Trx. Any info at all would be greatly appreciated. Frank.
