Please sanity check my proposed system

Thanks. So, just to be clear, you are saying that I have to connect the ST40 to the i70 using a Seatalk to SeatalkNG converter, and not just a Seatalk to SeatalkNG Adaptor cable? (ie part A06073) I am confused because section 3.4 of the i70 installation manual states Connections to an existing SeaTalk system must be made using either a SeaTalk to SeaTalkng adaptor cable or a SeaTalk to
SeaTalkng converter?

Quote:The i70 can not be connected directly to the DeviceNet adapter cable, both the i70 and the DeviceNet adapter cable will need to be connected to a Seatalk NG backbone in order to communicate via Seatalk NG/NMEA 2000.

Again, section 3.5 of the i70 installation manual suggests in a diagram labelled Connecting the display to an existing NMEA2000 (DeviceNet)
backbone That I don't need to establish a SeatalkNG backbone?

Understood about the Actisense part - that is the part I'm looking at.

Thanks in advance for the clarifications!
