00:01 Welcome to the Spoken tutorial on “Connecting SBHS to Computer”.
00:05 We would call Single Board Heater System as SBHS in this tutorial.
00:12 In this spoken tutorial we will learn to set up physical communication between SBHS and computer to install USB driver.
00:21 To work with SBHS, we would require SBHS with power cable and USB/RS232 communication cable.
00:35 On a windows machine, we would also require FTDI Virtual Com Port USB driver corresponding to the OS on your computer
00:44 You may download it from : [www.ftdichip.com/Drivers/VCP.htm]
00:54 Let me show you this website
00:59 On this web site, scroll down and choose the driver file corresponding to your OS.
01:09 I have downloaded 32 bit 2.08.14 driver file for Windows
01:22 The single board heater system and your computer can be connected using a USB cable or RS232 cable.
01:30 Identify the corresponding ports on your computer and SBHS.
01:35 Here is an image of the USB port you will find on the back panel of a computer.
01:44 A Serial port on the computer back panel
01:49 USB and Serial port on the SBHS
01:54 Please note that before deciding to use RS232 cable, confirm the availability of RS232 port on your computer.
02:04 After you choose between USB and the seraial cabale 232, you have to do some corresponding jumper settings
02:12 A jumper is just a small black color connector.
02:17 A pair of these is shown here, each jumper can connect two terminals
02:26 The connectors on SBHS with both the jumpers removed is as shown in the figure.
02:33 Here we can see that there are three terminals on either side.
02:39 We can also see the labels USB and RS232 being printed besides these connectors on the PCB.
02:50 The center terminal on either side is the common terminal.
02:55 Take a jumper and connect the common terminal of one side and the terminal closer to the label USB of the same side.
03:06 Take another jumper and do the same thing for the other side.
03:11 This is how you set the jumpers to choose the USB port for communication
03:17 Similarly one can put both the jumpers on common terminal and the terminal towards the label RS232 to choose the RS232 port for communication
03:29 I have configured the jumper settings to choose USB port as shown.
03:38 After the jumper setting is done, connect the power cable to a 3 pin 230 Volt AC house hold socket and the SBHS
03:51 Switch the mains power ON there may or may not be an ON/OFF switch on the SMPS of the SBHS, below the power cabel connector
04:06 If the device is succesfully powerd, the display should turn ON
04:12 Here is an image of the display on SBHS.
04:16 Note that what is actually seen on the display may vary from what is shown. But it should certainly not be blank.
04:25 After powering ON the SBHS, connect the appropriate USB/RS232 cabel to the SBHS and the computer.
04:33 Here is an illustration of USB cabel connected to SBHS and the laptop
04:42 Always make sure that you First Power ON the device and Then connect the USB/RS232 cable.
04:52 Next we will see driver installation
04:56 Recall that the FTDI VCP USB driver was downloaded earlier from ftdichip.com
05:04 You can also find here a guide for driver installation download the guide from [www.ftdichip.com]
05:13 Let us go to this website
05:22 In the left panel, Click on “Drivers”
05:27 In the dropdown menu, choose “VCP Drivers”
05:33 Click on the “Installation Guides” link on the web page
05:41 Choose the required Operating system document
05:46 Since I am using Windows 7 Operating System, I have refered to “Windows 7 Installation Guide”.
05:55 You may choose the Operating System Guide according to your requirment .
06:00 This guide has detailed step by step instructions for driver installation.
06:07 Let me show you the Windows 7 PDF guide file.
06:14 Follow the steps as explained in this guide and install the driver.
06:21 The typical steps involved are
06:28 Opening the device manager
06:40 Locating the USB port
06:51 Putting the driver path
07:03 And Repeating the steps once more
07:08 Once the driver is successfully installed,
07:12 You should get the device listed under COM & LPT
07:20 Let me show you this over here
07:28 Your device should also get a COM number.
07:32 Here for example it is shown as COM 3
07:45 Now, Let us summarise what we learnt in this tutorial:
07:51 First is Connect the SBHS and computer. This involves choosing RS232/USB port Jumper settings Powering ON the SBHS
08:05 Second Install USB driver, downloading the installation guide following the guide and installing the driver
08:17 Watch the video available at [1].
08:27 It summarises the Spoken Tutorial project. If you do not have good bandwidth, you can download and watch it
08:37 The Spoken Tutorial Project Team conducts workshops using spoken tutorials, gives certificates to those who pass an online test
08:48 For more details, please write to contact @spoken-tutorial.org
08:56 Spoken Tutorial Project is a part of the Talk to a Teacher project.
09:00 It is supported by the National Mission on Education through ICT, MHRD, Government of India
09:07 More information on this Mission is available at: [2]
09:18 Thanks for joining,this is Rupak Rokade from IIT Bombay signing off.
