The device was connected to a 5V supply and an oscilloscope used to measure the output pin. The output pin is high when no signal is being received. Pointing a remote control at the sensor and pressing any button caused a pulse stream to be seen on the scope, the output dropping to zero and returning to it natural high state afterwards. As far as docking is concerned, I will just be interested in detecting a signal and not decoding it so we just need to detect a falling edge (perhaps with suitable error suppression).
