An example: 

In this example, receiver and transmitter modules are connected separately to two Arduino boards. The transmitter data pin is connected to Pin 12 of Arduino and the receiver data pin is connected to Pin 11 of Arduino.

Data pin of transmitter module to Pin 12 of Arduino.
Data pin of receiver module to Pin 11 of Arduino.
Please note that there are two separate Arduinos for each module.
