These drivers are for the USB cable that runs from your Pulse Oximeter to your computer. This cable is a special serial to USB cable (CP210x USB to UART Bridge VCP). You will only be able to use your SPO2 monitor with the special cable that came with it! (pictured below)

  1. I have Mac OS Sierra 10.12.6
    I’ve downloaded and installed your Mac driver. I plug in the oximeter and it doesn’t show up in finder. I try using SleepyHead to download data. SleepyHead can’t find the driver either. Do you have a step by step set of instructions I can follow so I can make sure I’m not missing something?

    1. Did you receive any respond?

      I am not able to download the driver –
      It says: FORBIDDEN to access the serve.

      SPO2 Alternatives for OSX: Error page,

  2. …it would help a listing of all the dlls AND OTHER FILES THAT SHOULD BE INSTALLED FOR WINDOWS TO RECOGNIZE THE CABLE

  3. Where can I buy this special cable? — mine went missing. And you are absolutely positive no other USB cable will work with it? First time I have ever seen this. And… the company does not indicate this in their product specifications. It’s not that I don’t believe you (I do), it’s just very odd and something I have never seen before.
