NGT-1 NMEA 2000 to PC Interface
Safely connect your PC to your NMEA 2000 network.
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.

Both versions are available with the SeaTalkNG to NMEA 2000 adaptor Cable - STNG-A06045

The SeaTalk NG to NMEA 2000® adaptor cable (STNG-A06045) is not available as a standalone product and must be bought as part of a bundle.

The firewall feature in the NGT-1 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.

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.

Progress stages:
[1] Collaboration between Actisense and the software developer has been agreed
[2] Software developer has issued a beta release version that supports the Actisense NGT-1
[3] Beta release version has been tested by Actisense and confirmed as working (in beta form).

[4] Software developer has issued full release version that supports the Actisense NGT-1
[5] Full release version has been tested by Actisense and confirmed as working

[6] Actisense tests have determined the software is safe for use on the NMEA 2000 network¹
[7] Actisense TPG tests complete and application for NMEA 2000 certification has been submitted
[8] NMEA 2000 Approved for use with the Actisense NGT-1 certificate issued by the NMEA

¹ Once the Actisense NGT-1 has been 'Third Party Gateway' (TPG) certified (the specification of which is currently being finalised by the NMEA), Actisense will be able to perform the NMEA 2000 Certifications tests on the software applications above.

When the combined 'NGT-1 & software application' is proven not to have compromised the NGT-1's NMEA 2000 certification during the required tests, Actisense will be able to apply for NMEA 2000 Certification on behalf of the software developer. The NMEA will then issue a certificate stating that the software is 'NMEA 2000 Approved for use with an Actisense NGT-1'.
