Overview
The Raymarine T122 is a wireless NMEA interface that links wired NMEA 0183 electronics to the Micronet Wireless network. It runs on 9-24 V DC, supports NMEA 0183 version 2.30, and gives you two input channels plus one output channel for moving navigation data into a Micronet setup.
On a boat with Micronet displays, this interface lets data from a GPS, chartplotter, autopilot, or onboard PC move onto the wireless network without adding another data cable run to each display. It is a practical fit when the rest of the system already speaks NMEA 0183 and you want key information visible around the boat through Micronet instruments.
Key features
- Bridges wired NMEA 0183 equipment into the Micronet Wireless network
- Supports NMEA 0183 version 2.30 for compatibility with common marine electronics
- Two NMEA input channels and one output channel for flexible system layout
- Runs from the boat's 9-24 V DC supply, so it suits both 12 V and 24 V systems
- External alarm connector for tying alerts into the onboard system
- Lightweight 135 g housing that is easy to mount near existing instrument wiring
Compatibility and fit
The T122 works with Micronet wireless instruments and with onboard equipment that outputs or accepts NMEA 0183 data. It handles the core data types most boaters care about, including depth, heading, wind, position, waypoint, and speed-related information, so it makes sense on boats that need to share navigation data between older wired electronics and wireless displays.
Before buying, confirm that the source electronics provide NMEA 0183 connections. This interface is built around that standard, so it is best suited to boats where the existing chartplotter, autopilot, GPS receiver, or PC already communicates over 0183.
Installation and setup
The unit is powered from the boat's DC system, which keeps installation straightforward on either 12 V or 24 V boats as long as supply voltage stays within the 9-24 V range. Mounting is simplest when the interface is placed close to the source wiring and in a protected spot where cable runs can be secured cleanly.
Its low weight helps when space is limited behind a panel or at the nav station. The external alarm connection is useful on installations where warning output needs to be tied into the rest of the onboard system.
Use on board
This interface is a strong match for owners who already use Micronet displays and want to bring in data from a GPS, autopilot, chartplotter, or navigation PC without adding extra display wiring around the boat. It also suits setups where navigation or tactical software data needs to be visible on deck through the Micronet network.
Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.

These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.
Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.
Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.
Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.
To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
