No advice from out there?
Just as well. I worked it out tonight - the bugger is a code-hopper.
I did tune the Rhino to the right frequency. The light on it glowed much brighter than anywhere else in the frequency range. Strangely enough, anywhere through the range the Rhino would respond with the three pulses to say it had learnt the code!???
I powered off the receiver (connected to the motor). I programmed the Rhino. I switched on the receiver and pushed the button on the Rhino and the receiver responded, starting the motor. BUT any more presses on the Rhino button were not acknowledged. I turned off the receiver and repeated the training of the Rhino and it did the same again - one hit and that was it!
So the Airport is obviously code-hopping. I cannot fully understand the logic of how they communicate and keep in sync, but I know this UHF transmitter won't work.
Anyone want to buy the Rhino off me?
