Vcc
2.5-5.5V DC input. The power supply needs to be a stable regulated voltage with <10mV ripple
GND
Ground connection.
OP1-3
These outputs are asserted LOW when the relevant inputs (S1 – S3) on the RF803E are asserted.
(see latch/unlatch information under ‘LKIN’).
RX DATA
This is the data input to the decoder it may be connected directly to the RF receiver module.
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.
SERIAL / OP TIMING
Multi-functional pin
This pin is read on power up to sets the action of outputs 1-3, Momentary action is set by a
connection to ground through a 2K2 ohm resistor, latching is set using open circuit.
In normal run mode this pin outputs serial data on reception of a valid data string.
