What is SeaTalk NG?

← Back

STNG is Raymarine’s own version of NMEA 2000 cables and connectors. They contain 1 extra wire, allowing for integration with their older, proprietary SeaTalk 1 data and devices. SeaTalkNG utilises the NMEA 2000 standard, allowing any NMEA 2000 certified device to interface on an STNG Network with the required adapter cables.
