HT12D AND HT12E PDF

This project has been design around HT12E and HT12D encoder / decoder chips from Holtek. With jumper selectable address on the receiver. The HT12E Encoder ICs are series of CMOS LSIs for Remote Control system applications. They are capable of Encoding 12 bit of information which consists of 8. Robokits India HT12E & HT12D Encoder and Decoder IC for RF Modules [RKI- ] – The HT 12E Encoder ICs are series of CMOS LSIs for Remote Control.

Try to get thin solid wire 24 AWG I believe. Found this item with same quality and at a lower price but prefer to buy from robokits. Return and Refund Policy. Thanks a lot for helping us to maintain competitive prices. We will notify you the result by email. Thanks for all your awnser, after studying a little bit into the RF module I found out my problem, anc left side of both encoder and decoder are the Address PIN, which means they will only communicate if ht122d addresses are the same, that ht12s what I was making wrong, I left them all at 1 and changed the resistors in them both cause the TX need to have 20 times the resistence of the receiver, in other words 50k and 1M resistors.
