I used this with the Oximeter that I purchased. It came with it. I suspect that it only works with that brand of Oximeter.
I use it with Bluetooth. It connects well either via Bluetooth or USB. It is fairly intuitive and generates a very professional looking report.
I really wish you had mentioned which model you had purchased as I am trying to locate one for a Contac pulse oximeter CMS501 and so far, can't find anything - secondly IF there were a file that allowed his model to work on a mac, that would even be more of a plus to find out
