A folder named '''scilab codes local '''will be created.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"|

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| 
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Make sure the '''SBHS''' is connected to your computer and it is powered ON.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Right click on '''My Computer >> Properties'''
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| First, we will check the communication port number assigned to the '''SBHS.'''


To do this, right click on '''My Computer '''and then click on '''Properties'''. 

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Click on '''Device Manager'''
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| A window will open up.


In this window, click on the '''Device Manager'''. 


Please note that the look and feel of '''Windows 7''' is completely different from other '''Windows''' versions.


You may also need to vary the steps that I demonstrate here to suit your '''Windows''' version.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Point to the list displayed >> point to '''ports (COM & LPT)''' option.
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| The '''device manager''' will show you a list of hardware devices on your computer. 


Locate the '''ports (COM & LPT)''' option.


Here it is.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Double click on the '''Ports(COM & LPT)''' option
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Double-click on this option to open it.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Show the options under '''Ports(COM & LPT)'''
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| If you have connected '''RS232''' cable, then look for '''communications Port COM1.'''


Else look for '''USB Serial Port'''. 


For '''RS232''' connection, the port number mostly remains '''COM1'''. 


For a '''USB''' connection, it may change to some other number. 


Note down the appropriate '''COM''' number.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Click on the identified COM port number
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| In my case it is '''COM14.'''


Sometimes the '''COM''' port number you get after connecting a '''USB''' cable, is a two-digit number.


The '''serial tool box''' which connects your board and computer, can handle only single-digit port number.


Hence, it is necessary to change your '''COM''' port number.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Double-click on the COM port
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Let me show you the procedure to change the '''COM''' port number.


Double-click on that particular '''COM''' port.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Click on the '''Port Settings''' tab
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Click on the '''Port Settings''' tab.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Click on '''Advanced'''.
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Then click on '''Advanced.'''

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| In '''COM port number''' dropdown >> choose any single-digit number.
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| In the '''COM port number''' dropdown menu, choose the port number to any other single-digit number.


'''Windows''' may show you that all ports are currently in use. 


But, in reality, this is only the old status.


Hence, you can forcibly use a particular '''COM''' port number, if there is no other '''USB''' device connected.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Click on OK

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Click on '''OK'''
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Click on '''OK''' to close the '''Properties''' window.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Click on the close option on the '''Device Manager'''
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Close the '''Device Manager''' and the remaining windows.

Let me show you this file.


Switch to the '''step test''' folder.


The steps after launching of '''scilab''' till opening '''xcos''' can be executed using '''start.sce''' file.

Usage of '''start.sce''' file is recommended only after you get a firm understanding of the process.


This file assumes that the '''port''' number provided in the '''ser underscore init.sce '''file is correct.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Click on the S'''top''' option

After completing the experiment, let us reset the '''SBHS'''.


Let me switch to the slides again to illustrate this.

To reset, press the '''Reset''' button for 1 or 2 seconds and then release it.


The '''reset''' operation makes '''Heat''' 0% and '''Fan''' 100%.


However '''0''' is displayed for both on the '''LCD'''.

Let me show you this file.

The name of the '''data file''' is in the format of a time stamp.


Read the '''data file''' name as Year Month Date Hours Minutes Seconds dot txt.

|-

It has values of '''heat, fan '''and''' temperature''' for every sample.


Hence, this file can be used for analysis purpose.
