NGT-1
NMEA 2000® to PC Interface
Interface your PC to the NMEA 2000 bus with a functional firewall gateway...
The Actisense NGT-1 is the only intelligent NMEA 2000 gateway available to
precisely transfer messages to and from the NMEA 2000 bus.
The diagnostic NMEA Reader software allows viewing of NMEA 2000 messages with
configuration options, enabling the set-up of all Actisense products on the NMEA
2000 bus.
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 firewall feature enforces the NMEA 2000 bus rules, so software
manufacturers 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 welcomes enquiries from software manufacturers who would like to
incorporate NMEA 2000 and the NGT-1 into their software.
Benefits of the NGT-1:
- Sends and receives pure NMEA 2000 data
- Configure and flash-update Actisense products on the NMEA 2000 bus
- Use with NMEA Reader to help diagnose network problems
- Provides a rule-enforcing firewall between a PC and an NMEA 2000 bus
- NGT-1-USB and NGT-1-ISO versions available to suit all installations

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.
