NGW-1 NMEA Conversion Gateway
Upgrade to NMEA 2000 while keeping your NMEA 0183 devices installed.
The Actisense NGW-1 NMEA 2000 Gateway is the easiest way to link between a boats old and new data networks. The NGW-1 can convert NMEA 0183 data into NMEA 2000 data and vice-versa.
The NGW-1 is available to purchase in a variety of options:
NGW-1-ISO is the standard option. With an opto-isolated input and ISO-Drive output for direct NMEA 0183 device bi-directional connection.

NGW-1-ISO-AIS is the NMEA 0183 AIS option that enables the conversion of NMEA 0183 AIS data to its equivalent in NMEA 2000. This provides an 'out of the box' solution for quick installation with no configuration required.

NGW-1-USB is the NMEA 0183 USB (1.1 and 2.0) interface for bi-directional connection to a PC for use with NMEA 0183 software.

Every option of the NGW-1 is available with the SeaTalkNG to NMEA 2000 adaptor Cable - STNG-A06045. The SeaTalkNG to NMEA 2000® adaptor cable (STNG-A06045) is not available as a standalone product and must be bought as part of a bundle.

Please go to the Resources page to see the up to date list of conversions the various configurations can handle.

The Actisense NMEA Reader software utility allows the NGW-1 user to view and understand (in detail) the translated NMEA 0183 sentences output by an NGW-1 directly.
