... 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-ALPHA encoder is transmitting. The RF803D-ALPHA can be configured to work with an ALPHA TRX setting the TX/TRX pin.

... While a valid signal is present the Learn/RX LED output will toggle at high frequency (flicker LED) Note that this output will be valid whether or not, the RF803E-ALPHA has been learnt to the RF803D-ALPHA or not LRN This input is used to set the decoder module to ‘Learn Mode’ and for the ‘Erase Function’ and is also used to drive the Status LED ...

... In TX Mode the RF803E-ALPHA and RF803D-ALPHA can be used with ALPHA-433TX and ALPHA-433RX respectively. When an input is activated on the RF803E-ALPHA it is sent to the RF803D-ALPHA where it is then mirrored on the output pins for an long as the signal is being received. When used in TRX mode the RF803E-ALPHA and RF803D-ALPHA must be used with ALPHA- 433TRX ...

... Serial data is output initially and again every ½ second whilst data is being received from the RF803E-ALPHA transmitter. i.e. this output is valid regardless of whether the RF803E-ALPHA encoder has been learnt to the RF803D-ALPHA decoder or not. The serial data packet contains a learn bit to show if an encoder input is learnt. ...

... To mark the end of the serial packet ascii characters for carriage return (hex 0D) are sent followed by LF (hex 0A). Custom Versions Custom versions of the RF803E-ALPHA / RF803D-ALPHA chipset are available to provide a bespoke remote chipset for OEM applications.
