Connecting SeaTalk1 and NMEA2000 using the SeaTalk Converter

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Rick,

Q1. Do I need the Raymarine SeaTalk1 to SeaTalkng Converter Kit (E22158) to connect the two networks and share data between the devices on both networks?
A1. Yes.

Q2. Do I connect the SeaTalk converter and the NMEA2000 network with a “backbone” connection (with the NMEA2000 backbone connecting to both ends of the SeaTalk converter using DeviceNet Adapter Cables A06045 and A06078)?
A2. While the ST-STng Converter will be installed as a backbone component, it will need to be interfaced to the Maretron backbone using SeaTalkng Backbone Cables. Maretron offers field installable DeviceNet M/F plug which may be installed on the SeaTalkng backbone cables to permit one end of each cable to be mated to Maretron backbone.

Q3. Will the NMEA2000 supply the power to the SeaTalk converter and the SeaTalk1 network or does power need to be connected to the SeaTalk converter?
A3. The backbone will supply power to SeaTalk bus. Care must be taken to ensure that the source of power for the SeaTalk bus (often the red terminal of an autopilot's SeaTalk port) will not be connected to the SeaTalk bus.

Additionally, each SeaTalk to SeaTalkng Converter will support a SeaTalk bus of up to five SeaTalk devices. Should the SeaTalk bus feature more than five devices then the bus will need to be divided into smaller busses of no less than five devices each.
