Question for users of the Contour machines

Does anyone use the contour machine? If so do you use the software to help manage your glucose levels? I have thought about using it, but I was wondering if anyone had the cable to hook their machine up to a computer? If so could they post a pic.
I am a geek so I naturally have tons of cables laying around and I have tried alot of them so far. I just want to make sure that I have the cable I need and that way I know if it’s a software issues or a lack of the proper cable causing my computer to not see my glucose machine,
