Fully NMEA 2000 Certified
The handy firewall feature enforces the NMEA 2000 bus rules, so software developers can create compliant software at a fraction of the direct certification costs. The supporting Actisense Software Development Kit (SDK) helps to reduce the required development time.
With the upcoming ‘Third Party Gateway’ status, leading chart plotter software will be able to be certified to work with the NGT-1.
Actisense encourges software manufacturers who would like to incorporate NMEA 2000 and the NGT-1 into their software to contact them.
The NGT-1 is available in two versions:
NGT-1-USB is the standard option – USB interface for bi-directional connection to a PC.
NGT-1-ISO is a more specialist option – Opto-isolated input and ISO-Drive output for a direct PC bi-directional connection.

The Actisense NGT-1 is an NMEA 2000 certified Gateway device, enabling software applications to both read and send NMEA 2000 messages in a protected environment. The electrical isolation and firewall capabilities of the NGT-1 place it in a unique position as a computer Interface to NMEA 2000.
Actisense is committed to supporting software developers to create a wide range of NMEA 2000 capable applications for the PC, Mac & Linux. The initial list includes chart-plotters, vessel monitoring, data logging and Ethernet server applications that can display NMEA 2000 data, and/or share their own NMEA 2000 data with other devices on the network.
Below is the current list of software that is either already compatible with, or in the process of being made compatible with the Actisense NGT-1. The table indicates the development progress state of each software application to help clarify the current compatibility position (the stage key is detailed below the table). Actisense advise that customers should check with software developers to determine whether both the NGT-1-USB and NGT-1-ISO versions of the Gateway device are supported.
Please contact Actisense if you are a software developer and would like a low-cost way to incorporate NMEA 2000 and the NGT-1 into your software package.
