Digital Yacht ST-NMEA (ISO) Converter

The Digital Yacht ST-NMEA (ISO) Converter is the ideal data converter for any legacy Autohelm or Raymarine system

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 and thousands of boats around the world that have a SeaTalk¹ network and many owners, for one reason or another, need to convert from SeaTalk to NMEA0183.

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 or are located in an area that is hard to access.

Digital Yacht's SeaTalk to NMEA (ISO) Converter is a small but powerful interface that provides bi-directional conversion between a SeaTalk network and an NMEA0183 network or device. Taking its power from the SeaTalk network, the ST-NMEA Converter features a full, multi-transistor SeaTalk¹ interface, an opto-isolated NMEA0183 input and differential NMEA0183 output that allows key navigational data to be reliably shared between the SeaTalk and NMEA0183 networks.

For developers and advanced users who 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 (ISO) Converter is ideal for connection to one of Digital Yacht's wireless NMEA servers (Sold Separately), allowing SeaTalk owners to go wireless and a USB Version of the ST-NMEA Converter (Sold Separately) is also available for direct connection to a PC or Mac.

Features:

• Small but powerful bi-directional converter
• Powered from the SeaTalk network
• Features reliable multi-stage transistor SeaTalk interface
• Opto-isolated NMEA0183 input and differential NMEA0183 output
• Can be configured to operate in "Raw Data" mode ($STALK)
• Converts all of the key navigational data
