RCR Series Receivers
Long Range Wireless Applications
303, 433 MHz
Remote Control Receiver
The RCR303 is a remote control receiver designed to
provide a quick and cost effective solution for a variety of
wireless applications. The receiver includes an external
antenna, decoder and relay driver (open collector)
outputs. The receiver offers excellent sensitivity and
selectivity by the utilization of SAW technology and
state–of-the-art low noise amplifiers. An external jack is
provided for external antenna. Two different decoder
options are available, one “learning” and the other with
DIP switch settable addressing (Holtek decoder).

Decoder options
“A” Series Decoder
Address is set via cutting or shorting traces to create a “high”, “low” or “open” circuit for each address bit. Setting the
address for the transmitters is the same. Default from factory is all “low”. A total of 38 or 6561 address are available.
“B” Series Decoder
This receiver will learn up to 4 different transmitter ID’s. A total of 210 or 1024 addresses are available. The
transmitters are pre-addressed at the factory.
To learn a transmitter, power up the receiver, remove the antenna, and then press the learn button. The Learn LED
will light. With the transmitter close to the receiver (a few feet), press any button on the keyfob transmitter. When the
Learn LED goes out, the transmitter has been learned. To learn another transmitter, repeat the process. When a
fifth transmitter is learned, the first transmitter learned is eliminated from flash memory.
For operation in high EMI environments (such as around electric motors), the “B” series receiver performs somewhat
better than the “A” series.
