RF output modules produced and sold from October 2019, requires software ver. 4.8.x or newer.

This is due to hardware changes (new modulator circuit) on the output modules QAM, COFDM and PAL.

If you have TDX or TDH running a software version 4.7.x or older and you need to expand the system (or replace a faulty output module), please upgrade the complete system to newest software version.


An easy way to identify the modules requiring the sw. ver. 4.8.x or newer, is to look at the pre-loaded software version on the box.

In this example the DVB-C (QAM) output module requires the software 4.8.x or newer.
