The receiver includes an external antenna, decoder and relay driver (open collector) outputs. The receiver offers excellent sensitivity and selectivity by the utilizat ion 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). Features Typical Applications

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 2 10 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, repe at 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 electr ic motors), the “B” series receiver performs somewhat better than the “A” series.
