Janny,
  Running rtty split with two DAX channels requires that you use two slices..used DAX 1 on slice A and DAX 2 on slice B.  In your RTTY program, select DAX1 RX for receive ( caputre ) and DAX 2 TX for transmit ( playback).  You should see appropriate  displays in the the DAX control panel. with DAX 1 enabled for RX and DAX 2 enabled for TX.

Janny,
  How many channels show up in the DAX control panel? Can DAX 2 be enabled for TX?  If you go the  windows control panel>manager audio devices, do any DAX 2 channels show up there ??  ( you may have to enable' show disabled devices' ) 
  You may have to uninstall and reinstall DAX.

  In your RTTY program, do other DAX channels show but DAX 2 is missing ?  There is nothing magic about DAX 2 if another one is available.. Some RTTY programs can not display all the DAX channels that are installed.

Janny,
   What DAX TX devices show up in the Windows Audio Device Manager ? Do They show up in your RTTY program ?

That looks okay..  Since you are showing signals in the Windows Audio Control panel for Reserved TX2, that means that signals are being presented to the radio.  See attached..
Note:: In lower right corner.. High cutoff must be above tone frequencies. 
Note DAX button must be enabled in the P/CW panel.
Note: During transmit,the level meter indicates signal.

Your close..
