Receiver Decoder RF803D
Functional Description
The RF803D is simple to use. As shown in the typical application circuits, in the stand alone
operation the RF803D has the capability to learn up to 15 unique RF803E transmitters.
The RF803D is connected directly to the data output of a radio receiver module and upon detection
of a valid data packet it will decode the data stream. The RF803D will then assert its digital outputs
which will match the state of the RF803E encoders’ learnt at the time of transmission.
The digital outputs may be configured as latching or momentary action.
Latch = the output will change state on each successive transmit of the encoder.
Momentary = the output will only operate for as long as the RF803E encoder is transmitting.
The RF803D requires only the addition of the following components
1. A ‘Learn’ switch which is used in the process of learning a transmitter/encoder to the decoder
2. An LED which indicates the status of the learn process, the erase process and also data
3. An Option link which configures the action of the digital outputs. This input may simply be tied
Compatibility with RF Solutions Transmitters:
The RF803 series are compatible with the FireFly/FireBlade series and 205 series of ready to
operate transmitter encoders (when using FM)
This enables a designer to integrate a remote control function into an application easily, by using a
ready made transmitter.
and also to initiate erasure of encoder information.
