The Actisense NGT-1 ISO is the only intelligent NMEA 2000 gateway that sends available messages precisely to and from the NMEA 2000 bus.
The advantages of using the NGT-1:
Send and receive pure NMEA 2000 data.
Configure and flash-update Actisense products on the NMEA 2000 bus
Use with NMEA Reader to diagnose network problems
Provides a control-dependent firewall between a PC and an NMEA 2000 bus
NGT-1-USB and NGT-1-ISO versions available for all installations
The NGT-1 is available in two versions:
NGT-1-USB is the standard version - USB interface for bi-directional connection to a PC.
NGT-1-ISO is a more specialized option - Opto-isolated input and ISO Drive output for direct PC bidirectional connection.
The firewall feature enforces NMEA 2000 bus rules, allowing software manufacturers to create compliant software at a fraction of the direct certification cost. The supporting Actisense Software Development Kit (SDK) helps 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.
