ALPHA Encoder / Decoder IC’s

RF803-ALPHA

Transmitter Encoder RF803E-ALPHA

Functional Description

The RF803E-ALPHA is a simple device to use. As shown in the application circuit below, it

requires only the addition of input switches and an ALPHA-TRX RF Module for use as the

transmitter in an end application. Transmission is automatic without user intervention.

The ID is designed to run in continuous sleep mode; on detecting a switch closure The

RF803E-APLHA will wake up transmit a secure data packet on the TX output.

The RF803E-ALPHA can be set as a simple transmit device, or, to expect an acknowledgement

signal back from the decoder.

The type of transmissions to send may also be configured

–

Transmit only on state change,

–

Transmit continuously whilst input is active.
