AIS650 connection to SeaTalkng converter

[Petersailor]

Hi,
I shall install a AIS650 and I have a SeaTalk to SeaTalkng converter in my system close to where there AIS will be installed, see attached picture what connections are unoccupied on this converter.

From my MFD e7 I have a spur cable connected to the spur port of a SeaTalkng T-piece. I have removed one of the blue SeaTalkng Termination plugs from the SeaTalk to SeaTalkng Converter and connected this plug to one of the end blue backbone ports of the SeaTalkng T-piece, and
connected a SeaTalkng Backbone Cable from the unoccupied blue SeaTalkng backbone port of the SeaTalk to SeaTalkng Converter to the unoccupied blue backbone port of the SeaTalkng T-Piece.

Can I connect a SeaTalkng spur cable from the AIS650 direct into the SeaTalk to SeaTalkng Converter on one of the unoccupied white ports?
Or do I have to install another SeaTalkng T-piece?
