CONTROLING THE ELECTRICAL APPLIANCES USING PC’S
INTRODUCTION

 It can be used to control the printer as well as house hold and other electrical appliances.
 The computer program included as part of the project and implimentation controls ‘RELAYS’ through the interface circuit,which in turn, switch the appliances ‘ON’ or ‘OFF’.
 The parallel port has 12 output including 8 data lines and 4 control lines
THE PARALLEL PORT
The parallel port or line printer terminal is found on the back of a PC as a D –type 25 pin female connector.
* The port is composed of:-
-> 4 control lines
-> 5 status lines and
-> 8 data lines
*The original parallel port is a bundel of three ports.
These are
-> data port
-> status port and
-> control port
* Each of them having specific addresses assigned to them
PIN DIAGRAM FOR PARALLEL PORT
 We are using DB25 connector for parallel port.
 Pins 2 through 9 from the 8 –bit data output port.
 Pins 1, 14, 16, and 17 from the control port which is capable of reading / writing.
 Pins 10 through 13 and pin 15 together form the status port.
IDENTIFY THE MEMORY LOCATION FOR A PARTICULAR MACHINE.
 To identify the assingments for a particular machine:-
->the DOS debug program can be used to display memory locations.
 For example:- >debug- d 0040:0008 L 80040:0008
78 03 78 02 00 08 00 00
 Thus according to the addresses displayed it follows that the address of the data port is 0*0378 and so on.
The basic circuit has the following components
 Relay
 One 470 ohm resistance
 One 4.7k ohm resistance
 One opto-couplar IC numbered MCT2E.
 One transister numbered BC148
 A diode numbered IN4007.
COMPONENT DESCRIPTION
 OPTO-COUPLER
-> is an integrated circuit.
-> number of the IC used is MCT2E
-> it is a combination of a light source and a photosensitive detector.
-> MCT2E opto-coupler IC is used in this circuit is a 6 pin IC.
 THE PIN-NUMBERING AND THE CORRESPONDING FUNCTION ARE AS FOLLOWS:-
