The Design And Construction Of Cable Control Device For Arrangement And Easy Identification Of Cables

ABSTRACT

This work is on cable control device for arrangement and easy identification of cables.It is design for easy identifying fault wire. In this work IC 4017 is used as counter to display the output. The 555 timer IC is used to generate the PWM signal for 4017 IC. Both the major components are discussed along with their working in this work. A cable tester can identify if the wires are paired correctly. It can also show if there is a break in the insulation, a situation which allows crosstalk between two wires that should not be connected. The tester can also tell whether the cable has the proper level of resistance

1.1                                            BACKGROUND OF THE STUDY

The idea behind the design and construction of this system is to make available or alternative means providing safety and accuracy demand in flow of signals in network cables. This goes a long way in helping to curb the problem frequently encountered as a result of open circuit and unwanted connection, in the wire (Anis et al., 2017).

When connected to an Ethernet cable, a cable control device tells if the cable is capable of carrying an Ethernet signal. If the cable carries the signal, this indicates that all the circuits are closed, meaning that electric current can move unimpeded through the wires, and that there are no short circuits, or unwanted connections, in the wire. Cable control device vary in complexity and price, but a basic tester consists of a source of electrical current, a measuring device that shows if the cable is good, and a connection between the two, usually the cable itself(Anis et al., 2017).

Cable control device used in Ethernet cable allows computers in the network to “talk” to each other. An Ethernet cable has wires that are arranged in pairs. For current to flow correctly, the wire pairs must be connected in the proper order.

A cable control device can identify if the wires are paired correctly. It can also show if there is a break in the insulation, a situation which allows crosstalk between two wires that should not be connected. The system can also tell whether the cable has the proper level of resistance (Guoqiang et al., 2013).

If a network isn’t working correctly, the problem is frequently user error or other problems. It will rarely be a faulty cable. A cable control device is more frequently used to tell whether a patch cable will work before it is connected. The cabling should first be examined visually to identify any obvious problems. If everything looks correct, a cable control device may then be used.

A cable control device is a simple apparatus that merely identifies whether current flows through the cable, or it may be a professional-level, complex device that gives additional information that helps identify the problem. Professional-level cable control device may not only tell if an open circuit exists, but may identify where the break is located. Some also identify the gauge of wire used and can generate their own signal to test for interference (Harfoush et al., 2013).

Basic cable control device can test for simple connectivity issues but may not identify other problems that cause the cable to malfunction (Christhu , 2015). Cabling may not work when it is near a source of interference or if the cable is too long. Intermittent faults may develop that do not show up when the cable is tested. Sometimes the problem is not sustained long enough to show up on the tester.

1.2      STATEMENT OF THE PROBLEM

Several studies have shown that the majority of network performance problems occur in or near the users’ desktop/laptop computer.  These problems include, but are not limited to, duplex mismatch conditions on Ethernet/FastEthernet links, incorrectly set TCP buffers in the user’s computer, or problems with the local network infrastructure.  The work is designed to quickly and easily identify a specific set of conditions that are known to impact network performance (Begg et al., 2016).  A multi-level series of plain language messages, suitable for novice users, and detailed test results, suitable for a network engineer, are generated and available to the user.  Finally, the test results may be easily emailed to the appropriate administrator to assist in the problem resolution phase.

Another problem is the inability of the testing personnel to use the instrument accurately. When these tester is not used accurately that means that an incorrect result is expected to be seen(Christhu , 2015).

1.3                                  AIM AND OBJECTIVES OF THE PROJECT

The aim of this study is to build a low cost cable control device. The objectives of the study are:

1. To build the system prototype at low cost
2. To easily identify faulty cables

• To verify that all of the intended connections exist and that there are no unintended connections in the cable being tested.

1.4                                              PURPOSE OF THE PROJECT

The purpose of this work is to design and construct a cable control devicethat can be used to identify if the wires are paired correctly. It can also show if there is a break in the insulation, a situation which allows crosstalk between two wires that should not be connected, which can  also tell whether the cable has the proper level of resistance.

1.5                                SIGNIFICANCE OF PROJECT

This study will serve as an easier means of identifying and arranging cables thereby making computer network easier for users to share multiple resources and access shared files. This study will also serve as an avenue ofmaking student involved becoming familiar with 555 timer and decade counter connections and operation.

1.6                                                   SCOPE OF THE STUDY

The scope of this work covers building a system that is use for easy identifying fault wire. In this work IC 4017 is used as counter to display the output. The 555 timer IC is used to generate the PWM signal for 4017 IC. Both the major components are discussed along with their working in this work.

1.7                                          APPLICATIONS OF THE SYSTEM

• It can be used for telephone wires and for network cable RJ45 testing and fault identification.
• It conducts two tests, i.e., master and remote that can take a role in analysis easier.
• It can be used for identifying the improper connection wires or short-circuit point in the cable.
