NGT-1 NMEA 2000® to PC Interface NMEA 2000® to PC Interface
Interface your PC to the NMEA 2000® bus.

The NGT-1 is an intelligent NMEA 2000 gateway able to precisely Transfer messages to and from the NMEA 2000 bus. It is compatible with a wide range of Chartplotters, display and configuration applications available for PCs.

The diagnostic NMEA Reader software allows viewing of NMEA 2000 messages with configuration options, enabling some set-up of Actisense products on the NMEA 2000 bus.

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 welcomes enquiries from software manufacturers who would like to incorporate NMEA 2000 and the NGT-1 into their software.
