Detailed description

The RAYMARINE T122 wireless NMEA interface is designed for converting and transmitting NMEA 0183 data to the Micronet wireless system. This device receives and sends NMEA 0183 sentences in version 2.30, enabling integration of existing equipment into a Micronet network. It is powered by a 12/24V DC source, ensuring stable and long-lasting operation on board.

Connectivity and NMEA 0183 compatibility

The T122 interface handles a range of NMEA 0183 V2.30 sentences, both for receiving and transmitting. Received signals include DBT (depth), DPT (depth with offset), GLL (latitude/longitude position), HDG (heading), HDM (magnetic heading), MTW (water temperature), MWV (wind), RMB (route to waypoint), RMC (minimum navigation data), VHW (speed and heading over ground), VLW (distance traveled) and VWR (relative wind). For transmission, it supports DPT, GLL, HDG, MTW, MWVR (true wind), MWVT (true wind), RMB, RMC, VHW, VLW and VWR. Only available data is transmitted, ensuring optimized data management.

Installation and marine environment

For optimal performance and increased durability, the RAYMARINE T122 must be mounted in a dry area of the boat to protect cables and connectors from corrosion. It is also advisable to avoid metallic surfaces or metallic objects between the interface housing and other Micronet instruments to optimize wireless signal quality. For ideal transmission, a transverse rather than longitudinal mounting relative to the boat’s axis is recommended. Connection to the ship’s 12/24V DC power supply is advised for reliable long-term operation, compared to using auxiliary batteries. The installation kit includes a mounting template, three mounting screws, and a terminal screwdriver, facilitating precise and secure surface installation.

« Wireless NMEA 0183 integration and transmission for Micronet systems »

The RAYMARINE T122 interface is a relevant solution for navigators looking to modernize an existing NMEA 0183 system without replacing all their instrumentation. Its gateway function allows integrating NMEA 0183 sensors into a wireless Micronet network, providing display flexibility on compatible screens or repeaters without complex additional wiring. It is particularly suited to sailboats and pleasure craft equipped with older-generation instruments whose data (wind, depth, GPS) remains reliable and useful.

Installation requires a direct 12/24V DC power supply, which is standard onboard. The choice of location is critical: although the device is designed for the marine environment, positioning it in a dry area away from metal masses is essential for the device's longevity and the quality of the wireless connection. Compared to newer NMEA 2000 converters, the T122 positions itself as an economical solution to extend the lifespan of an NMEA 0183 system toward wireless display. It does not convert to NMEA 2000, which is a limitation to consider for integration with more modern systems. However, for a Micronet ecosystem, it perfectly fulfills its role as an NMEA 0183 data aggregator.

What is the Raymarine T122 wireless NMEA interface used for?

The Raymarine T122 wireless NMEA interface is designed to convert and transmit NMEA 0183 data to the Micronet wireless system. It enables integration of existing equipment using the NMEA 0183 protocol into a Micronet network, facilitating communication between your instruments.

Which NMEA 0183 sentences are supported by the T122 interface?

The T122 interface handles a range of NMEA 0183 V2.30 sentences, both for reception and transmission:

Received signals: DBT (depth), DPT (depth with offset), GLL (lat/lon position), HDG (heading), HDM (magnetic heading), MTW (water temperature), MWV (wind), RMB (route to waypoint), RMC (minimum navigation data), VHW (speed and heading over ground), VLW (distance traveled) and VWR (relative wind).Transmitted signals: DPT, GLL, HDG, MTW, MWVR (true wind), MWVT (true wind), RMB, RMC, VHW, VLW and VWR.Only available data is transmitted, ensuring optimized data management.

How should the T122 wireless NMEA interface be powered?

For optimal performance and reliable operation, the T122 wireless NMEA interface should be powered using the boat's 12/24V DC supply. This connection is recommended over auxiliary battery power.

Where should I install the T122 interface on my boat for optimal signal?

For optimal performance and increased durability, the T122 interface must be mounted in a dry area of the boat to protect cables and connectors from corrosion. It is also advisable to avoid metal surfaces or metal objects between the interface housing and other Micronet instruments to optimize wireless signal quality. For ideal transmission, a transverse rather than longitudinal mounting relative to the boat's axis is recommended.

What tools are required to install the T122 wireless NMEA interface?

To install the T122 wireless NMEA interface, you will need the following tools:

A 2.5mm drill bitAn electric drillA Phillips screwdriverA terminal screwdriver (supplied with the product)

Which items are included in the T122 interface installation kit?

The T122 interface installation kit includes the following items:

A mounting templateThree mounting screwsA terminal screwdriverDouble-sided adhesive tape

Is the T122 interface compatible with all versions of the NMEA 0183 protocol?

No, the T122 interface is specifically designed for receiving and transmitting NMEA 0183 sentences version 2.30. It is important to check the NMEA 0183 version of your existing equipment to ensure full compatibility.

How should I connect and secure the cables for the T122 interface?

To connect and secure the cables:

Connect the cable ends to the provided connectors using a screwdriver, ensuring the wire colors are matched.It is recommended to sleeve the ground wire to prevent any risk of short circuit once the cover is reinstalled.Insert the connectors into the appropriate sockets on the interface and loop each conductor inside the housing. This will allow the outer cable sheath to be secured under the rubber clamp when the cover is installed.Secure the cables near the interface to reduce the risk of future connection loss.
