NMEA Conversion Gateway - NGW-1
Connnecting to an NMEA 2000 Network
The illustration below provides an example of the minimum requirements for an NMEA 2000 network. If an
NMEA 2000 network is not currently installed, Actisense has a variety of
Starter Kits
available.
The horizontal cable illustrating the backbone is not always needed in reality as a backbone can be formed
by simply connecting T-pieces directly to each other. The cable connecting a device to a T-piece must not
exceed 6 metres as defined in the NMEA 2000 specification:

Connnecting to a SeaTalkNG Network
Raymarines SeaTalkNG network uses exactly the same data as a standard NMEA 2000 network. The
only difference is the physical network connections. To connect any standard NMEA 2000 device (like
the NGW-1) to an STNG network, simply use an NMEA 2000 to STNG adapter cable (product code:
STNG-A06045
) between the device and the STNG network.
