Interface with Saphir comfort RC and X Panel

[temuccio]

Hello, I am trying to connect to a Truma Saphir comfort RC controlled by a Truma iNet X Panel. I have connected the LIN converter to the free RJ11 port of the Saphir (the other port is occupied by the Truma iNet X Panel).

This is what I see passing through, and furthermore, I can't find the "PR SET" command on the X Panel... Is it necessary to have the CP Plus controller?
