The Raymarine SeaTalk 1 to SeaTalkNG Converter Kit (E22158) allows legacy SeaTalk 1 devices and instruments—such as ST40, ST60+, Raystar 125 GPS sensors, and LifeTag systems—to seamlessly integrate and communicate with a modern SeaTalkNG / NMEA 2000 network. It acts as an inline bridge, translating legacy SeaTalk data into SeaTalkNG messages without replacing existing operational equipment.
