Happy DIY user using Siemens Pure binax 7 bx and Connexx 8.3 with Hi-Pro device

First of all that is Good Work! You should be proud.

There’s a couple of problems with the software link you provided.

  1. It’s not the current version. The current version is Siemens/Signia Connexx8.4.2/SiFit8.4.26 for newer/current. Though, for Connexx 8 the Updater feature can be used to update older versions.
  2. It’s the wrong database (HTFit/Hansafit/Hansaton) It should be the (SiFit/Siemens) database.

You don’t have to search the Internet for Connexx software. The links are available here in this forum.
