[DG] [DG] p70s Not Reading ST50 & ST60 Instruments

[Derek - Raymarine - Moderator]

Hi Ramvet,
thanks for the details.

Looking at the diagram you sent, make sure there are terminators, (the small blue plugs) fitted at the extreme ends of the backbone, ie one blur plug in position A and the other blue plug in the empty blue socket of the T Piece that the p70s is plugged in to.

Secondly, the red 12v core of the cable connecting the ST50/ST60 displays to the SeaTalk to SeaTalk NG Converter must be cut and insulated. This prevents two 12 v power supplies to the SeaTalk to SeaTalkNG converter, the converter must only have a single power supply and this should come from the STng network.

Hope this helps?
Regards
Derek
