The S20-433A4L00 has 4 send buttons and works with 433.92MHz and AM modulation mode. The 10pin coding switch enables you to set 1,024 different security codes. For example, you can make subsequent transmitters a duplicate of the original transmitter by setting the same code. The receiver then requires no further memory space, so the number of transmitters is virtually unlimited. Equally, you can also set the same code for several transmitters in order to control the same receiver with all the transmitters.
