Where can I purchase a data cable for my Optium Xceed meter?

I am diabetic and use the Optium Xceed blood glucose monitoring system to monitor my blood glucose levels.

I have discovered that it is possible to connect my meter to my laptop or desktop computer and upload the memory contents. In order to do this I require special software that I have downloaded and a special data cable. This cable is of a unique design and so cannot be found in typical hardware stores.

Does anybody know where I can find and buy such a cable on the internet?
