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 website, 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 serial cable 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 successfully powered, 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 cable to the SBHS and the computer.
04:33 Here is an illustration of USB cable 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 requirement .
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 http://spoken-tutorial.org/What_is_a_Spoken_Tutorial
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 http://spoken-tutorial.org/NMEICT-Intro
09:18 Thanks for joining. This is Rupak Rokade from IIT Bombay, signing off.
