edgellmh,

Something doesn't quite seem correct in your setup or with the Transciever units.  The "test hookup" should indicate via a LED on the receiver if the button on the Transmitter is being pressed or not.

The main thing to look for is that the 'TX-RX/SEL' pin is tied to Vdd when using the Transciever unit as a Transmitter, and that the 'TX-RX/SEL' pin is tied to Vss when using the Transciever unit as a Receiver.

Other than that you can treat the DATA pin as an INPUT on the Transmitter, and as an OUTPUT on the Receiver.

Once this basic communication configuration can be established, you can send more complex signals such as serial communication over the DATA line from one Transceiver unit to the next.

Is there any way that you can provide a picture of the Transmitter and Receiver setup as you currently have it connected?
