Under the "Select products Catagory" dropdown choose "GPS Receiver/Data Logger".
Under the "Select products series" dropdown choose "Mouse Type GPS Receiver" and
click on Submit. A new page opens showing various receivers. Scroll down to the GR-213u
GPS Receiver and see the one called "GR-213u Driver Program-Vista Driver". It is of a type
of file compression called "rar" which may require a unzip program. I use a free program,
"Secure Zip for Windows". Click on the little yellow box at the far right of the "GR-213u
Driver Program-Vista Driver" line. It will be labeled "9618869.rar". Save the file.
It should be found by clicking on the Vista START and then your user name & should be in
the "Downloads" folder as "9618869.rar".
Creat a new folder for the actual unzipped file by clicking on the the Vista START Icon
& then "Documents". Click on the "Organize" tab & then on the dropdown "New Folder".
Name the new folder "Holux Vista Drvr" & then open it.
Now back at the "Downloads" folder open (Unzip) the "9618869.rar" file. Copy the new
folder "GR-213u Driver Program-Vista Driver" to the "Holux Vista Drvr" folder you created
in "Documents", so that you can later delete all those files that may have built up in
"Downloads"folder from doing lots of downloading.
Open the "GR-213u Driver Program-Vista Driver" folder & see the setup file
"PL2303_Prolific_Vista_3301.exe". The size should be about 2724 KB. Open it to start the
driver install. Now you are almost done.
After Vista has done its driver install, go to "Control Panel" & open "Device Manager".
Now plug in your Holux GR-213 & the "Device Manager" should now show a new entry
called "Ports (COM & LPT). Click on the little + sign to expand it & you should see
"Prolific USB-to-Serial Comm Port (COM#)". The # represents your Comm Port number
used by the Holux. Right click on "Prolific USB-to-Serial Comm Port (COM#)" & click on
the dropdown "Properties". Click on the tab "Port Settings"at the top of the "Properties"
window. Change the value in "Bits per second" from 9600 to 4800 & click OK.
Hopefully you have installed the Holux Utility "GPS Viewer" with a shortcut on the
desktop. Open the "GPS Viewer" & click on "Scan". A new window "GPS Scanning" opens
showing GPS found at the same Comm Port # that shows in the "Device Manager". Click on
OK & the scan window closes now showing the same Comm Port#. Click on "Open GPS" &
then on "Cold Start or Warm Start" & all the satellites found should show up. You can close
the "GPS Viewer" & all the other open windows. If all went as described any software you
used with Win XP using GPS should work OK now with Vista.
Now run your software (MS S&T or whatever) & make sure its GPS Settings show the same
Comm Port# as in "GPS Viewer" & baud rate of 4800.
