NGT-1: NMEA 2000 PC Interface
The NGT-1 allows NMEA 2000/SeaTalkNG messages to be read by an application and also allows that application to send NMEA 2000 messages back to the network.
The NGT-1 does not understand NMEA 0183.
The most common variant sold is the NGT-1-USB as that is the easiest method of getting NMEA 2000 data to a PC. We also sell the NGT-1-ISO for customers who do not want USB (and its drivers) in their system.
An NGT-1 working with NMEA Reader is a very powerful NMEA 2000 network diagnostic tool.
Please check with your software developer to ensure they support the NGT-1-USB or NGT-1-ISO
NGW-1: NMEA 2000 to NMEA 0183 Gateway
The NGW-1 converts between the old and the new NMEA protocols bi-directionally. It cannot be used to transfer NMEA 2000 messages to the PC; the serial port only understands NMEA 0183.
The most common variant sold is the NGW-1-ISO for direct connection to an NMEA 0183 Talker/Listener device. We also sell the NGW-1-USB for customers who want an easy method of getting NMEA 0183 data to their PC.
An NGW-1 makes it possible for new and old NMEA devices to share data.
Note: As NMEA 2000 has more functionality than NMEA 0183, it is not always possible to create a conversion. In the latest version of NMEA 0183 released in June 2012, there are 148 sentences with between 550 & 570 data fields. In total contrast, in the latest version of NMEA 2000 released in February 2015, there are 163 PGN messages and 1569 data fields.
