ABSTRACT
The aim of this project is to design and construct a LAN Cable Tester .It
is a tool for testing LAN cables to find all the problems associated with the cable.
The fault in any of the wire in the cable can easily be detected by the use of this small but useful instrument and the speed can be enhanced very easily which was earlier dumped by the cable fault.
One of the primary objectives of an Engineer is to end eavor to deliver the best product or the most efficient services at the lowest cost to the end user. Our project was found to meet the expected results. This project uses coding in assembly language to provide a very efficient algorithm for carrying out the required task. The block diagram, the associated technology, algorithms, the software and hardware requirements are all well illustrated to assist good understanding. As of true for most project effort of this nature, progress also contributes after the work. For this reason we devoted a significant effort to the selection of techniques whose value is likely to remain applicable in a rapidly involving body of knowledge. We had immense benefit from this project in that we learned a great deal in the domain of Network Cable Testing which was entirely a new field for us to work and we trust that this project gives contribute in this field. As is true of most writing efforts of this nature, progress continues after the work on the manuscript stop.
For this reason, we devoted significant effort to the selection of the material that we believe is fundamental, and whose values likely to be applicable in a rapidly evolving body of knowledge.
WORKING:
In this project, we use one microcontroller to control all the transfer voltage and one LCD to display the messages.
We use 89s52 controller, which is a family member of the 8051 controllers. We use 2 lines and 16 characters LCD to display the message on the screen. Along with the LCD and microcontroller, we use total 16 LEDs to check the continuity of wire.
Out of 16 LEDs, 8 LEDs are for the input signal and 8 for the output signal. We use 5 volt regulated supply for the whole circuit. For this, we can either use step down transformer to step down the voltage or 7805 regulator to reduce the voltage from 9 volt to 5 volt dc.
In this project we show that how we can check the LAN or any other cable with the smart point to point checking method. In this method of wire testing, we pass voltage from one end to another end to each wire. If the wire passes the voltage successfully, then connected LED is ON and LCD shows a message on screen. So microcontroller checks all the eight wires one by one and shows the result on LCD. If all the points are okay then LCD display an ‘OK’ message. If even a single wire is not transferring the voltage, then LCD shows a ‘NOT OK’ message.
