TX-4MSIL and HT12E/D

[zhaniko93]

Hello, I have a problem with encoder/decoder and RF module. I have bought HT12E/D encoder/decoder and BC-NBK / TX-4MSIL AUREL RF Receiver / Transmitter and aren't they compatitible with each other? In Datasheet it's written that RF modules can handle MAX 2 Khz (Receiver and 4KHZ Transmitter) , Its written: Square wave output MAX 2Khz and Encoder/Decoder work on 150 khz oscillator (Decoder and 3Khz Encoder) and when I connected, it doesn't work (for 30 times I Connect 1 pin, 1 times it transmits succesfully and 29 fails) and what should I do? Do I have to Buy resistors for lower Frequency for E/D? Datasheets:

P.S. I have 1.1Mohm and 51Kohm as It's recomended, But there's writen that I can make them work with lower frequencies and can you tell me how many ohms are needed for such frequency to work with me RF Modules?

Oh, and almost forgot... When I connected RF module output to LED, and iput to button, when I turned On, led started winking fast and when I presed the button, led turned on or off for 0.1 sec and continued winking and why? It has to transmit the bit of transmitter pin and it was winking in both situations

I read that Breadboard is bad for RF becouse of It's capacitance and is it the reason? When connecting Encoder's Dout to Din, Circuit works well. here's pic:

when I put one of the antennas off the circuit, it works almost well, 2-3 fails from 20 and hat can I do?

finally, sometimes It does and sometimes doesnt and Is it Breadboard's Fault?

hi,
Bread boards are not suitable for RF work, to much inter connector stray capacitance.
