This article is for TDX/TDH installations running very old software (sw. ver. 1.x / 2.x / 3.x)
TRIAX strongly recommend updating the TDX/TDH software to version 4.x or 5.x or 6.x .... Download the software here
These new versions are using HTML5 instead of Silverlight and are supported by modern browsers like Edge, Firefox, Chrome and Safari.
The Silverlight software is not supported by new Microsoft Edge, Mozilla Firefox and Google Chrome browsers.
This is a problem when connecting to a TDX/THD running software 1.x, 2.x or 3.x.
In these software versions, Silverlight is used by the TDX/TDH as graphical user interface engine.
Browsers that support Silverlight:
Microsoft Edge
The Edge browser can be configured to use "Internet Explorer mode". This way it will support the Silverlight runtime.
