RF Receiver Module
Introduction:-
RF Transmitter/Receiver module is based on HT12E/HT12D Encoder/Decoder IC. This
Receiver PCB can support both 8pin & 3pin RF Modules and 315/433MHz Modules. 8-way DIP
switch is used to select 8-bit binary address. (The address of both RX-TX should be same for
valid communication). Receiver Module receives RF signal which is then passed to HT12D
decoder IC which 1st verifies the source address. If source address of the signal matches with its
own address then this IC decodes the 4-bit DATA and that data is reflected at pin 1~4 of 10P
Box Header. This data can be then used as per application.

Features:
Compatible with all Campus Component Pvt. Ltd. µController Boards.
On Board HT12D connection
On Board ASK module with 315/433Mhz Frequency
4 channel RF communication support
Valid transmission indicator.
8‐bit DIP switches to change the address bits.
Hardware Description:
RF module connectors:
The 8-pin and 3-pin bergstick connector is provided for connecting RF module.
Either 433 MHz module or 315 MHz module can be used. While using 433MHz module
it is connected to 8-pin berg stick connector whereas 315 MHz module can be connected
to 3-pin connector.

Box Header:
10P Box header is used to read the 4-bit data received by controller. Its pin
configuration is shown below:
8-bit DIP switches:
The status of each address pin can be individually pre-set to logic “high” or “low”
using these DIP switches. The serially received status of the 8 bits of address is scanned
in the order from A0 to A7 by the HT 12D decoder.
Note:- The address setting for both RX/TX boards should exactly be same. Otherwise Receiver
will reject the data. Multiple active Transmitters in same area will cause interference.
HT12D decoder IC :
The IC has 8-bit Address (A0 toA7) and 4-bit data i.e. from D8 to D11.
The address bits from A0 to A7 are connected to DIP Switches. The serial data
received from the RF module is converted into 4-bit data by this decoder IC and is
available on Pin no. from 10 to 13.This data bits are then used by the controller by
connecting it to the box header.
