The Raymarine T122 Wireless NMEA Interface enables seamless NMEA 0183 integration between autopilots, GPS receivers, chartplotters, onboard PCs, and Raymarine Micronet wireless instrument displays.
Designed for sailboats and performance racing applications, the T122 (Model T122) features NMEA 0183 Version 2.3 compatibility with two inputs and one output, 9–24V DC power supply support, and wireless data transmission to Micronet displays.
Lightweight at just 135g (0.3 lb), this marine NMEA interface allows navigation, tactical software, and instrument data to be viewed anywhere on deck without complex rewiring.
T122 Product Overview
The Raymarine T122 Wireless NMEA Interface is designed to integrate third-party marine electronics into the Raymarine Micronet instrument system. It collects NMEA data from compatible devices and transmits it wirelessly to Micronet displays, eliminating the need for extensive cabling throughout the vessel.
Ideal for sailboats, racing yachts, cruising boats, and performance marine applications, the T122 enhances onboard data visibility while maintaining a clean, efficient installation.
Key Features
• NMEA 0183 Version 2.3 compatible
• Two NMEA inputs and one NMEA output
• Wireless data transmission to Micronet displays
• 9–24 V DC external power supply
• External alarm connector
• Lightweight design – only 135g (0.3 lbs)
• Compact housing for easy installation
Wireless Integration for Micronet Systems
The T122 allows sailors to integrate:
• Autopilots
• GPS receivers
• Chartplotters
• PDAs
• Onboard PCs
• Navigation and tactical software
Data collected from these devices is transmitted wirelessly to Micronet instrument displays, allowing performance and navigation data to be monitored anywhere on deck.
When connected to an onboard PC, Micronet can both send and receive information, enabling advanced navigation and tactical software display functionality.
Custom Display Capability
The Wireless NMEA Interface can be used with PC software to create custom instrument pages on the Raymarine T110 Micronet Digital Display using proprietary NMEA sentences.
This makes it especially valuable for racing applications and performance-oriented sailors who require customized data layouts.
