CHAPTER ONE

INTRODUCTION TO SIWES

1.1 OVERVIEW

The SIWES short for Student Industrial Work Experience Scheme is

a six month program that avails University, Polytechnic and

Colleges of Education students in Nigeria the opportunity to see

beyond the shores of what they are been taught in school most

especially the practical aspect of what is been taught in school.

It is a program funded by the Federal Government of the country

and controlled by two bodies the Industrial Training Fund (ITF)

and Nigerian University Commission (NUC).

SIWES established since 1973 has helped lots of students get work

experience, perform better in their academics and even secure

permanent employment even before finishing school. This program

is encouraged so as to help students of Engineering, science,

agriculture, medicals, management and other professional

education programs in the Nigerian Tertiary institution get to

know more of the theoretical works they do in school by getting

them exposed to the practical aspects and the reality of what

they do in school.

1.2 OBJECTIVES OF STUDENT INDUSTRIAL WORK EXPERIENCE SCHEME

{SIWES}

STUDENT INDUSTRIAL WORK EXPERIENCE SCHEME (SIWES) is indeed not

complete if it has no objectives behind its creation. Below are

specified some of the objectives attached to this program:

A. It exposes tertiary institution students to a more wider and

practical aspect of their course of study thereby making

them know more about what they are doing.

B. It brings to the mind of most students a full idea of what

their course is all about and how it can be applied in the

reality of life as most students are in school studying but

do not know what can be done with that which they are

studying when they go to the outside world.

C. SIWES helps students build up their social, occupational and

intellectual communication skills in their specialties they

get to know more during their attachment.

D. With industrial attachment, most students build up

connections that will help in securing employments after

school and others get work even before finishing school.

E. It also prepares students to contribute to the growth of the

working community and Nation as a whole.

F. To expose students to work methods and techniques in

handling equipments and machineries that may not be

available in tertiary institutions.

CHAPTER TWO

IT ACTIVITIES UNDERTAKEN

HARDWARE ACTIVITIES

DEFINITION: Hardware is any component or group of components that make up a

computer system or is useful and visible in any field of study.

Hardwares delivers more when they are in good shape and not

faulty or over-used as over-use decrements their useful life

thereby limiting their viability and output delivery.

HARDWARES ENCOUTERED: During my attachment with Lifestyle Technologies Limited, I came

across numerous hardwares many of which were new and others not

new. Some of the hardwares encountered are:

a) Occupancy Sensor : This is a standalone Lutron device

that can be used in a single room setup with its main

work been to sense the presence of a person in the home

or anywhere it is installed then signals the receiver

which triggers the light to come up.

b) Lutron Keypads: These are keypads that are quite easy

in their looks but complicated in their operations.

17

Their main duty is to enhance energy saving by helping

clients dim and control their lights as they will.

c) Lutron Panel : This is a panel that is used together

with the Lutron Keypads, Power modules, Terminals,

Lutron Processors and its main aim is to help integrate

lightening control in a wide environment like a whole

school or a whole house as the case may be.

d) Lutron Processors: The processor just like that of the

Computer System receives signals from all Lutron

devices and sends them to the appropriate receiving end

be it a keypad, light, television or any device as the

case maybe.

e) Lutron Cables: This cable is used to interconnect

Lutron devices together.

f) Crimping Tool: This is a networking tool that is used

to crimp cables or prepare them for use with a wireless

enabled device or devices. It is also used to attach a

RJ-45 port to ends of crimped cables.

g) Switchers : Switchers are of two kinds, we have that

which is used by the router or any wireless receiver

where it functions as a distributor of signals mostly

in cases where the device sending the signal has fewer

ports while the second one works with media systems.

h) Router : A wireless device that ensures efficient

forwarding of data bandwidth or signals between two

wireless devices. It is different from a switch in the

18

sense that a switch helps in forming a network while

the router distributes the signal that is shared by the

formed network.

i) Closed Circuit Television (CCTV) Cameras: These are

surveillance cameras that are wired and wireless

depending on what the client wants and enables the

clients who have them installed monitor their

surrounding either close or from a far.

j) Network Cables: These were used to enable networking

and amongst those used are; cat5, cat5e, cat6 (shielded

and unshielded pairs).

k) Camera Tester: This is a device that was used to test

and position the cameras well after mounting them to

ensure they are good and positioned well.

l) Digital Repeaters: They receive signals from devices

like occupancy sensors, telecoms and other devices and

sends them to the processor for further processing and

execution.

m) IR Receivers: These are normally attached to devices to

enhance control from positions where the devices are

not present at all. For instance controlling a device

in the control room by just pressing a button in the

family lounge.

n) RJ-45 Port: This is usually of two types, the shielded

and unshielded and both are used for same purpose only

that they are for different cases.

19

o) Plier : This is an electrical tool used to cut wires or

terminate them in cases where lightening control is

needed by a client and also in cases of full home

automation.

p) Saw: Saws are used at the initial stage of the work,

where pipes are directed according to the connections

that will be done later; they are used to cut pipes.

q) 20mm/25mm pipes: As the case may be, they are used for

channeling and setting up the direction of flow of the

cables and wires that are to be used for any contract

gotten by the company.

r) GRAFIK EYE Qs : this device is a Lutron device that

could replace the Lutron Panel but is mostly used when

it’s only a small space that is to be controlled other

than the panel that controls several rooms and space.

s) Learning Station: This is a copying device used to copy

the functionality of keys on devices that are to be

automated and integrated into a device.

t) DVR/NVR: These devices work with the CCTV cameras to

enhance their operability.

u) HDMI cables : These are cables that help in the

transmission of high quality video output.

v) HDMI extender and splitter: The extender is used to

connect long distance devices while the splitter is

used in cases where more than one output are in use

with just a single input source.

20

MOUNTING OF CCTV CAMERA (IP DOME)Tools needed: Screwdriver, Crimping tool, RJ-45 Port, Concrete

nails, Screws, Camera Tester, cat 5 or 5e cable.

Procedures:

a. Get the camera to be mounted and check if it indoors or

outdoors.

b. Get the network cable to be used and run it from the start

point to where the camera is to be mounted, remember this is

done through the earlier done piping. (In cases of analog

cameras, a coaxial cable either single strand or double

strand and a power cord).

c. Crimp the network cable used

d. Set the colors the right combination for a cross-over

connection which is WHITE ORANGE – ORANGE – WHITE GREEN –

BLUE – WHITE BLUE – GREEN – WHITE BROWN – BROWN.

e. At the end of the camera, there is an Ethernet connector,

use it to connect the crimped cable to the camera in

question.

f. Using the camera tester check for the suitable position to

screw the camera depending on the surface in question.

g. After setting the position right, using the concrete nails,

hold the mounting support to the surface then screw the

cameras to the mounting support.

21

h. After doing this, use the tester again to check the position

is well set after which you put down the mac address of the

camera.

FIXING OF LUTRON KEYPADS (BUTTON AND TOUCH SCREEN)Equipments needed: Lutron cable, plier, Lutron keypad,

screwdriver, pen, paper, screws and washer.

Procedures:

a. Fix the back box to the wall the keypad is to be fixed.

b. Get the Lutron keypad and dismount it into its different

components (base keypad, faceplate adapter, button kit and

faceplate).

c. Run the Lutron cable from the control room to that position

the keypad will be fixed. (NOTE: the cable has four strand

colored: Black, Red, White and Purple; each has its

different function)

d. Fix the base keypad to the back box first

e. After that, connect the wires appropriately after which you

place the faceplate adapter on the base keypad.

f. The button kit is placed next and finally the faceplate

which is the external covering is fixed last.

SOFTWARE ACTIVITIESComputer Softwares are series of codes that are put together by a

compiler so as to instruct the Computer System on what to do over

a specific period of time. Computer Hardwares are barren if

Softwares are not made available to the hardwares.

During my Industrial Attachment, I came across the following

Softwares though I did not make a very deep use of the Softwares.

Amongst those encountered are:

INTEGRATION DESIGNER Integration designer is a software developed by RTI (Remote

Technology Incorporated), a company that is fully based in

automation and integration. The software is usually used when

full integration is required. What is done involves using the

learning station to copy the behavior of that which is to be

integrated into any device then using the software, you pick the

device in question then integrate the copied functionality into

the device through IR interfaces on the integration designer.

After the modeling has been completed, with the help of the

router that is installed and configured, the completed work is

uploaded into the device in question through the RTI enabled

interface on the device after which the device can be used to

control all that has been automated using the Integration

designer software. Anytime there is a change in the specification

of the equipments to be controlled, all you have to do is to

27

amend using the local system then upload it to the router which

automatically uploads the one already in the device.

RTI PANEL APPLICATION

RTiPanel is an iOS application that is designed to run on iPad,

iPod and iPhone devices. This application communicates with RTI’s

XP series control processors to provide full control of your RTI

system right from your iPad or iPhone. The RTiPanel application

is designed to run on LAN and WAN networks giving full control

and two-way feedback from anywhere in the world. A license is

required for every Apple device in order to communicate. Licenses

may be purchased from the RTI online store.

This application is downloaded into the device in question and

the software integration Designer is used to create a function-

ability that is uploaded to the router then further to the

RTiPanel on the device in question.

LUTRON HOMEWORK QS

This software unlike the Integration designer is used only for

lightening programming and control. It is also installed into any

device it wants to be controlled from using same procedure as the

integration designer.

MICROSOFT WORD

This software is a word processing software we used to type our

quotation and proposals sent to clients for clearer explanation

and costing specification.

32

NETWORKING ACTIVITIESNetworking is the interlinking of several components to enhance

their efficient and effective harmonization and functioning of

the overall system. Here, it is possible for a single device to

communicate with several devices all in the same network region

and it supports for sharing o0f resources and equipments .

NETWORKING HARDWARES a) Crimping Tool: This is a networking tool that is used

to crimp cables or prepare them for use with a wireless

enabled device or devices. It is also used to attach a

RJ-45 port to ends of crimped cables.

b) Switchers: Switchers are of two kinds, we have that

which is used by the router or any wireless receiver

where it functions as a distributor of signals mostly

in cases where the device sending the signal has fewer

ports while the second one works with media systems.

c) Router : A wireless device that ensures efficient

forwarding of data bandwidth or signals between two

wireless devices. It is different from a switch in the

sense that a switch helps in forming a network while

the router distributes the signal that is shared by the

formed network.

d) RJ-45 ports: They are attached at the end of the

crimped cable to aid connection with devices. It is

also of two types; shielded and unshielded.

33

e) Network Cables: These were used to enable networking

and amongst those used are; cat5, cat5e, cat6 (shielded

and unshielded pairs).

f) Coaxial Cable: This is used for internet connection

setup and transmission to the network hub from the dish

where it is further distributed by the router.

g) Dish : This is responsible for collecting broadband

internet data and sending it to the network hub through

the coaxial cable for further transmission.

h) Network hub : Main collector of data signal from the

dish.

NETWORKING ACTIVITIES UNDERGONECRIMPING OF CAT-5 CABLE

PROCEDURES:

a. Get the necessary hardware devices needed ( crimping tool,

network cable, RJ-45 port )

b. Using the crimping tool, cut the length of cable needed for

the preparation

c. Using the crimping tool again, remove the shield on the

cable

d. Now separate the eight strands accordingly depending on the

connection style to be used.

e. Make sure they are all of same length and straight after

which you get the RJ-45 port to be used

34

f. Holding the RJ-45 port with back facing you, insert the

cable into it then using the crimping tool press it until

the whole cables are visible from the other side of the RJ-

PART THREE

RESULTS

39

CHAPTER THREEDEVELOPMENT, RECOMMENDATIONS AND CONCLUSIONDEVELOPMENTS

Amongst the skills acquired during my period of attachment are as

follows:

i. I can confidently crimp network cables for use for

networking

ii. Initially I have always wondered how some things I watch in

movies are but now I not only know how but I did some most

especially the home automation and integration aspect and

CCTV installation

iii. I was also able to identify and know more computer hardware

that I knew nothing about before the attachment

iv. Using the projector and controlling what it displays using a

system.

v. Also I got some skills in event coverage using surveillance

cameras.

vi. I also did learn the basics of access control for doors.

LIMITATIONS AND RECOMMENDATION

Well my industrial attachment was indeed a wonderful one and am

very grateful it has come to an end all in good shape. I must

say, it wasn’t an easy one though but I still thank God; during

this period, I encountered lots of challenges and amongst them

are listed below:

40

a. Inadequate facilities to aid my ad-hoc or complementary

learning when I get home after work especially practical

aspects.

b. Also encountered was financial difficulties and it resulted

in my missing work for some days and extra-classes I was

supposed to enroll for.

c. Finally and more hectic was the traffic issues as found in

my place of attachment. Despite I leave home early many a

time I still arrive late at work and most times some vital

activities had been completed leaving me to miss those.

d. Also encountered was the difficulty with which it was to get

an IT space

CONCLUSION

Despite the limitations and difficulties encountered, I

appreciate my boss, Mr. Success Chigbu who was understanding and

quite helpful during my attachment not forgetting every member of

Lifestyle Group for their unending support and readiness to teach

me at all time I ask.
