Emulator called “HyperTerminal”. On Windows XP, you can find it at Start → Programs
→ Accessories → Communications → HyperTerminal. In other versions it may be in different
places; consult the Windows documentation for details (OK, realistically just look around
until you find it). I will now try to tell you how to use HyperTerminal, although frankly
I'd rather you not use it because it is an appallingly badly designed piece of software.
Start HyperTerminal (from the Start button, depending on where it is on your version of
Windows™). The Connection Description dialog will appear. Click Cancel to get rid of
it. Now you just have the HyperTerminal main window.
Select File → Properties on the menu to bring up the New Connection Properties dialog.
On the Connect To tab of this dialog, bring down the Connect using: pick list and select
COM1 or COM2, etc., according to which serial port you are using on your computer. Then,
click the Configure... button to bring up the COMn Properties dialog. Set the five pick lists
as follows: Bits per second: to 9600, Data bits: to 8, Parity: to None, Stop bits: to 1 and Flow
control: to None. Click the OK button to accept these new settings and get rid of this
dialog. Now go to the Settings tab of the New Connection Properties dialog, which
should still be on the screen. Bring down the Emulation pick list and select TTY. Click the
ASCII Setup... button and the ASCII Setup dialog appears. Check the Send line ends with
line feeds checkbox. Click the OK button to finish this dialog. Everything else can be left
at its default value. Click the OK button to finish up configuration. You should once
again be back to the main window.
Select File → Save As... on the menu to bring back the Connection Description dialog. In
the Name edit box, type a suitable name that will allow you to remember what this
“connection” is for. For example, you might type “Mini-Scanner Update”. If you wish, you
can choose an icon from those presented. I rather like the one with the picture of an
atom. Click the OK button, whereupon the dialog will disappear and be replaced with the
Save As... browser dialog. HyperTerminal is offering to save a file describing the
connection in a place of its choosing on your computer. The filename is already filled in
from what you entered in the previous dialog. Accept this filename and location by
clicking Save. Again, you are back at the main window.
Now, exit HyperTerminal. It sounds silly, but do it. You can use File → Exit or click the
Close button (the one at top-right with a cross in it). Don't try to use HyperTerminal to
communicate with the Mini-Scanner at this point.
Go back to start HyperTerminal again, but now as you reach the end of your exploration
of the Start menu you will see two “HyperTerminal”s. The new one is a folder, (which
you can tell from the icon and the arrow pointing to another menu level). Continue to this
menu level and you should find the connection you just set up under the name you gave
it. Select this, and HyperTerminal will start up with all the configuration already done.
At this point, you have completed the configuration mentioned in step 3 of Firmware
Update Procedure, below. In future, at step 3, just start HyperTerminal using your preconfigured connection as described.
In step 6 of Firmware Update Procedure, you will need to send the firmware file to the
Mini-Scanner Flash Loader. To do this, select Transfer → Send Text File... on the menu to
bring up the Send Text File file browser dialog. Using this browser, locate the firmware
file on your computer, click on it to select it and then click the Open button. The dialog
will close and the file transfer will begin. You should see dots begin to appear in the
main HyperTerminal window as each record passes from the file to the Mini-Scanner and
