ST-NMEA (USB) Converter


“The ideal data converter to get SeaTalk data on to a computer”

The SeaTalk™ interface, originally developed by Autohelm in the early 1990’s, was included on pretty much all Autohelm and Rarmarine (and some Raytheon) products up until about 2012. As a result there are thousands and thousands of boats around the world that have a SeaTalk 1 network and many owners would like to get the SeaTalk data on to a PC, MAC or LINUX device.

Raymarine’s own SeaTalk to NMEA converter (E85001) is no longer available, and although some 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 NMEA (USB) Converter is a small but powerful interface that provides bi-directional conversion between a SeaTalk network and a computer’s USB interface. Taking its power from the SeaTalk network, the ST-NMEA Converter features a full, multi-transistor SeaTalk 1 interface and a high speed USB 2.0 interface that allows key navigational data to be reliably shared between the SeaTalk network and applications running on the computer.

For developers and advanced users that want to access the raw SeaTalk data, 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.

The ST-NMEA (USB) Converter is ideal for connection to any USB equipped computer (Windows/Mac/LINUX compatible), whilst an ISO Version of the ST-NMEA Converter is also available for direct connection to NMEA0183 systems.
