Problems with Littfinski feedback modules

Problems with Littfinski feedback modules
I have over the years been building a Märklin model railway. It is controlled with my computer using following setup:
Märklin control station CS1
Windigipet program on computer
Littfinski DEC-88 feedback modules and DSW-88 interfaces.
 
System has developed in size and some time ago I bought and install a HSI-88-USB interface.
I works using only one string for all my 11 DEC-88 modules - modules 1-13 connected and I get fine feedback from all of them.
 
Problem arises when trying to use three (3) strings connected as follows:
Modules 1-6 on String 1
Modules 7-10 on String 2
Modules 11-13 on String 3.
Here  I still only get feedback from modules in String 1.
Is there an explanation to this - missing setup in the HSI-88-USB?

I have asked Firma Littfinski about the problems, and Peter Littfinski responded:
“If feedback modules work fine on string "left" but not on string "middle" and "right", there must be a wrong setting in the Win-Digipet software. Please ask in the Win-Digipet forum, for the correct setting.”

Hello Søren,

when entering the settings in the WDP system settings, you have to enter the following:
-Module 1 to 6 String 1 WDP Start modul 1
-Module 1 to 4 String 2 WDP Start modul 7
-Module 1 to 3 String 3 WDP Start modul 11

The numbering starts with 1 for each string seperatly.

Markus
