Hi again,

The DSC-module has to be plugged into the special DSC-socket, thus avoiding to unplug the socket of the HF/RF-module. But indeed, 40 Euro...
I just checked the English handbook of the MC19, page 19. It seems the RF-module is just the same as on the mc14-15-16-16/20-18-20. And anyway, the mc19 uses the same slave-module ref. 3290.3, which means the same wire-connector as the mc15 which is described in my website for seeking the ppm-signal.
Or first check if you can find the ppm-signal at the DSC-connector.
I suggest you to make further postings via my personal mailaddres to be found on my website, this until you find the solution, that you then could divulgue here.

Hope it helps,
Olivier
