So there are four major places where problems may arise. Thank you for subscribing! sunny so thats mean, we can use 2 pair like this: T1 transmitter(433mhz) will send data to R1 receiver(433mhz) and then T2 tranmitter(315mhz) can take input from R1 receiver(433mhz) and again You will have to short the DOUT pin of the Encoder to the DIN pin of th Decoder.
It's any IC like HT12E/D that can take 6/8 parallel inputs? Reetesh Kocheta I am using three transmitter and three receiver sets, but now every receiver is showing no input signals.

Ligo George Yes, it will be possible.. Test Rf Remote Control Some of them have a built in … Rich Hi, I've built the encoder/decoder test circuit which isn't working properly, have changed the IC chips and get the same results. Please select a newsletter. Rakshith If I have two identical rf receivers placed at different distances from the rf transmitter.(let's assume they're differing by quite a distance.
Attempt these repairs with the understanding that it will cost more money and you still might not be able to fix what is wrong.With the higher cost of hobby-grade RCs, it RC vehicles communicate through radio signals between the receiver in the RC vehicle and a hand-held transmitter.
