DS600-10 March ‘06
Up to 7 unique encoders may be learnt to each RF600D. This can be extended to 48 encoders with the
use of the 93C76 EEPROM.
IN
This is the data input to the decoder, it may be connected directly to the RF receiver module or IR 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.
Learn Mode: is achieved by pulling this input to GND briefly
Erase Mode: is achieved by pulling this input to GND for >8 seconds. This causes the EEPROM to be
erased of all pre-learnt RF600E encoders.
Learn Operation using momentary push switch (As application circuit)
1. Press briefly and release the learn switch
2. The status LED will illuminate while the switch is pressed and remain on when released.
3. Operate the transmitter encoder once, status LED on the decoder will extinguish
4. Operate the transmitter encoder a second time, status LED on the decoder will flash
5. After the status LED has stopped flashing the transmitter has been successfully taught to the decoder
6. This transmitter will now operate the system
Erase Operation using momentary push switch (As application circuit)
To completely erase all transmitter data, press and hold the learn switch on the decoder for 8 seconds.
The status LED will illuminate continuously whilst the switch is held down and then flash while the decoder
erases all memory. It may take several seconds until the erase function is complete. After the status LED
is extinguished all the encoder identities are erased from the decoders eeprom memory.
SD1
Outputs serial ASCII data after each valid transmitter signal. (See previous section for more information)
LKIN
This high impedance input is used to set the digital outputs to momentary or latched actions
Momentary : Output is only asserted for the duration of the valid transmit signal.
Latching:
NB The outputs S0 – S3 can only be operated after a RF600E encoder has been learnt to the RF600D
decoder.
