Frequently Asked Questions

What are programming guides?


Ascensia Diabetes Care produces a variety of blood glucose meters, both with and without a computer interface. These documents describe the computer interface used by all of our blood glucose meters that have a computer interface. These programming guides provide technical information in order to facilitate the writing of computer programs that communicate with our blood glucose meters, including:

  • • The communication protocol for transmitting test results through the computer interface
  • • The communication protocol for configuring the meter and interrogating the meter configuration through the computer interface
  • • Sample communication sequences

What blood glucose meters from Ascensia currently have programming guides?


At the present time, programming guides are available for the following blood glucose meters: CONTOUR® NEXT, CONTOUR® NEXT USB, CONTOUR® USB, CONTOUR® NEXT EZ, CONTOUR®, CONTOUR® LINK, CONTOUR® TS, and BREEZE®2. The programming guides also include details on our legacy brand meters, like Ascensia and Glucometer.

How can I get notified when new programming guides become available?


When you sign up to receive the programming guides, we'll ask for your email and address to keep you up to date on the current releases of the programming guides. When new versions are available, we'll simply email you with a link to download any and all updated programming guides.

What can I do after I have developed a custom application using the programming guides?


Once you have developed your custom application, you should share the results of your testing with Ascensia's software contact. This will ensure your custom application is listed within our website and visible to patients and healthcare professionals, as a partner system compatible with Ascensia blood glucose meters.
