Raymarine VHF NMEA0183 to STNG Converter Kit

The Raymarine VHF NMEA0183 to STNG Converter Kit (E70196) bridges legacy and modern marine electronics, allowing older VHF radios and instruments communicating via NMEA0183 protocol to integrate seamlessly with Raymarine's advanced STNG (SeaTalkNG) network architecture. If you've invested in newer Raymarine multifunction displays, autopilots, or integrated navigation systems, but your VHF radio or depth sounder still communicates over NMEA0183, this converter kit eliminates incompatibility without replacing proven equipment. It's essential for mixed-generation boat electronics setups where upgrading everything at once isn't practical or cost-effective.

At its core, the kit includes an R52131 ST1 to STNG converter that translates NMEA0183 serial data into Raymarine's proprietary STNG digital backbone, enabling real-time data sharing across your network. The package ships with two A06031 STNG backbone terminators to properly terminate the network bus (critical for signal integrity), two A06032 blanking plugs for unused connectors, and a 2-meter A06071 adapter cable that converts STNG connections to bare wires compatible with 0183 devices. This architecture ensures minimal signal loss and allows your older instruments to report heading, speed, depth, and other critical data to your primary display—just as if they were native STNG devices.

Cruisers and weekend anglers with established electronics ecosystems benefit most from this converter, particularly those running Raymarine's e-Series or gS-Series displays paired with older Furuno, Lowrance, or Raymarine VHF radios. Installation requires basic familiarity with marine wiring and the STNG backbone topology; consult your Raymarine system documentation or contact a qualified marine electrician to ensure proper termination and network configuration. Weighing just 1 pound, the converter kit is compact and easily mounted in an engine room, cabinet, or helm station. Compatible with all Raymarine STNG-equipped systems, it represents a cost-effective upgrade path for boat owners unwilling to abandon reliable legacy instruments.
