Hey all!
I have just constructed a RF circuit to try out. I made use of the T5-434-5V and the R5-434-5-128 transmitter and receiver pair and also the HT12E and HT12D as the encoder and decoder for the transmitter and receiver respectively.
The schemetic I used can be found on page 6 of this datasheet: http://www.spelektroniikka.fi/kuvat/T5R5-434-5V.pdf
After following exactly, the circuit does not work. I connected the DOUT of the encoder and the DIN of the decoder directly and it works, which brings me to suspect it's the RF pair that's not working.
HT12E oscillator resistance: 1M ohm
HT12D oscillator resistance: 51K ohm
If anyone has any idea as to why the transmitting and receiving isn't working, your comments would be greatly appreciated!
Thanks!
