We would call Single Board Heater System as SBHS in this tutorial.

|-

# To set up physical communication between SBHS and computer 
# To install USB driver.

SBHS with power cable and USB/RS232 communication cable.

FTDI Virtual Com Port USB driver corresponding to the OS on your PC

You may download it from : 

[http://www.ftdichip.com/Drivers/VCP.htm www.ftdichip.com/Drivers/VCP.htm]


Let me show you this website

I have downloaded 32 bit 2.08.14 driver file for Windows

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Slide 5

Identify the corresponding ports on your computer and SBHS.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Slide 6

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Slide 7
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| A Serial port on the computer back panel




|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Slide 8
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| USB and Serial port on the SBHS


Please note that before deciding to use the RS232 cable, confirm the availability of RS232 port on your computer.


After you choose between USB and RS232, you have to do some corresponding jumper settings.


A jumper is just a small black color connector. 

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Slide 9
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| A pair of these is shown here.


Each jumper can connect two terminals

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Slide 10
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| The connectors on SBHS with both the jumpers removed is as shown in the figure.


Here we can see that there are three terminals on the either side.


We can also see the labels USB and RS232 being printed besides these connectors on the PCB.


The center terminal on either side is common terminal.


Take a jumper and connect the common terminal of one side and the terminal closer to the label USB of the same side.


Take another jumper and do the same thing for the other side.


This is how you set the jumpers to choose the USB port for communication


Similarly one can put both the jumpers on common terminal and the terminal towards the label RS232 to choose the RS232 port for communication

|-

Switch the mains power ON.


There may or may not be an ON/OFF switch on the SMPS of

the SBHS, besides the power cabel connector


If the device is succesfully powerd, the display should turn ON

Note that what is actually seen on the display may vary from what is shown. But it should certainly not be blank.

Here is an illustration for USB connection.

# First Power ON the device and 
# Then connect the USB/RS232 cable.

Recall that the FTDI VCP USB driver was downloaded earlier from ftdichip.com


You can also find here a guide for driver installation.

You may choose the OS Guide according to your requirment .


This guide has detailed step by step instructions for driver installation.


Let me show you the Windows 7 guide PDF file. 


Follow the steps as explained in the guide and install the driver.


The typical steps involved are 

# Opening the device manager
# Locating the USB port
# Putting the driver path
# Repeating the steps once more

Once the driver is successfully installed, 

# Your device should get listed under COM & LPT
# Your device should get a COM number.
