Goodmorning,

I have connected the e90w with a

Spx5
Multiple st60+ displays, for autopilot.
All connected by seatalk 1.

Now i have this st290 set, and wonder what route of connection
to go.

1. It would be preferred to connect it to the seatalkng port
Of the spx5.
2. Or using the seatalk ng port of the e90w.

But: i would like to also connect a ais and external gps.

I would like to hear what makes sense. Thanks.

Hello Wouter,

I would advise connecting the ST290s into the Seatalk1 network (via the Seatalk terminals on the ST290 DPU) and then connecting Seatalk1 to the E90W through a Seatalk1 - SeatalkNG convertor.

• Don't attempt to connect the ST290 to the rest of the system via either its Seatalk2 or NMEA2000 connections (the implementation of both was very early in the life of NMEA2000 and are not fully functional by today's standards).
• Don't connect the E90W to Seatalk1 or NMEA0183.
• Use SeatalkNG/NME2000 AIS and GPS (AIS700 and RS150 GPS) and everything should work well together.
  

Regards,
Tom
