I own an OXI receiver with a few remote controls. As I don't have a pinout of the receiver, I checked which of the 4 output pins react when the remote control is pushed.

I connected the 4 output of the 433MHz HF receiver to 4 digital inputs of an Arduino Duemillanove (with a piece of breadboard I already have for IR testing).

With a simple sketch, I detected an output pin toggles for about 500ms when one of the remote control's buttons is pushed. This receiver output will be connected to a digital input of my dual gate controller board.

The forth pin of the 10-pin header is toggling:
