I've searched for information related to InfodexM and DTR3, and on one website, it was mentioned that they work together, but that's it. The text was found in one document from FccID website. Apparently, InfodexM can be used only with DTR3. Also, I've searched for DTR3 and other supported applications, but didn't find anything available.
The PDF file is available here: https://fccid.io/pdf.php?id=78705
Note: It appears that InfodexM comes bundled with the software for DTR3.
