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. |
