The SeaTalk™ interface, originally developed by Autohelm in the early 1990’s, was included on pretty much all Autohelm and Raymarine (and some Raytheon) products up until about 2012. As a result there are thousands of boats around the world that have a SeaTalk 1 network. Many of these owners, for one reason or another, need to convert from SeaTalk to NMEA 0183 or to USB.
Raymarine’s own SeaTalk to NMEA converter (E85001) is no longer available. Although some of these instruments/MFDs/autopilots have NMEA0183 interfaces, they do not always convert all of the data and require additional NMEA to USB adaptors.
Digital Yacht’s SeaTalk to USB Converter is a small but powerful interface that provides bi-directional conversion between a SeaTalk network and a computer’s USB interface. The ST-NMEA converter takes its power from the SeaTalk network. It features a full, multi-transistor SeaTalk 1 interface and a high speed USB 2.0 interface. Therefore, key navigational data between the SeaTalk network and applications running on the computer can be shared reliably.
The ST-NMEA converter can also be configured to work in a special “Raw Data” mode ($STALK) which is gaining support in some Open Source projects. Developers and advanced users that want to access the raw SeaTalk data can take advantage of this.
This Seatalk to NMEA converter is ideal for connection to any USB equipped computer (Windows/Mac/LINUX compatible). An ISO Version of the ST-NMEA Converter is also available for direct connection to NMEA0183 systems.
