I have designed a remote controlled car with tws and rws modules with HT12E and HT12D encoder-decoder pair.But Though HT12D and HT12E is available ,I couldn't manage tws and rws.Instead of that I managed TXB1 and RXB1 modules.Can anybody please inform me whether these two modules work perfectly with HT12E and HT12D ?? I couldn't get it working with my all day's work today :S

Thanks in advance for anykind of advice.
