Please read this manual thoroughly before using the product to ensure safe and efficient operation.

2. Safety Information

Always observe the following precautions to prevent injury and damage to the equipment.

Ensure power is disconnected before installation or maintenance.
Do not expose the unit to extreme temperatures or direct sunlight for prolonged periods.
Consult a qualified technician for any repairs beyond basic troubleshooting.
Use only specified power sources and cables.

3. Setup and Installation

The FUR-IF-NMEA2K2 converter is designed for straightforward integration into existing marine electronic systems. Proper installation is crucial for optimal performance.

3.1 Unpacking and Inspection

Upon receiving the unit, carefully unpack it and inspect for any signs of damage. Ensure all components are present.

3.2 Mounting Location

Select a mounting location that is dry, protected from direct weather exposure, and allows for adequate ventilation. Avoid areas with high vibration or electromagnetic interference.

3.3 Wiring Connections

The converter features connections for both NMEA 0183 and NMEA 2000 networks. Refer to the diagram below for proper wiring.

FURUNO FUR-IF-NMEA2K2 NMEA Data Converter with NMEA 2000 connector and NMEA 0183 bare wires

Figure 1: FURUNO FUR-IF-NMEA2K2 NMEA Data Converter. The image displays the converter unit with a circular NMEA 2000 connector on one end and multiple color-coded bare wires for NMEA 0183 connections on the other. The main body of the converter is black with a label indicating "NMEA DATA CONVERTER", "TYPE IF-NMEA2K2", "SER.NO. 001866", and options for "NORMAL" or "HIGH SPEED (CUT ORANGE)" operation.

3.3.1 NMEA 2000 Connection

Connect the circular NMEA 2000 connector to your vessel's NMEA 2000 backbone. Ensure a secure, watertight connection.

3.3.2 NMEA 0183 Connection

The bare wires are for NMEA 0183 input and output. Refer to your NMEA 0183 device's manual for specific wiring requirements. Common connections include:

Data In (Rx): Connect to the NMEA 0183 Talker's Output (Tx).
Data Out (Tx): Connect to the NMEA 0183 Listener's Input (Rx).
Ground: Connect to the common ground of the NMEA 0183 system.

3.4 High-Speed Mode Selection

The converter supports a high-speed mode for specific data types. To enable high-speed mode (e.g., for heading and AIS data), locate the orange wire and follow the instructions on the converter's label. Typically, this involves cutting or connecting the orange wire as indicated for "HIGH SPEED (CUT ORANGE)" or "NORMAL" operation.

Note: Incorrect selection may lead to data transmission errors. Consult your system's requirements before altering this setting.

4. Operating Instructions

Once properly installed and powered, the FUR-IF-NMEA2K2 converter operates automatically, translating data between the connected NMEA 0183 and NMEA 2000 networks.

4.1 Power On

Ensure all connections are secure. Apply power to the NMEA 2000 network. The converter will power on automatically as it draws power from the NMEA 2000 bus.

4.2 Data Flow

The converter transparently translates NMEA 0183 sentences to NMEA 2000 PGNs (Parameter Group Numbers) and vice-versa. Verify data reception on your connected NMEA 0183 and NMEA 2000 devices.

NMEA 0183 to NMEA 2000: Data from NMEA 0183 talkers connected to the converter's input will be broadcast on the NMEA 2000 network.
NMEA 2000 to NMEA 0183: Relevant NMEA 2000 PGNs will be converted into NMEA 0183 sentences and output via the converter's NMEA 0183 output wires.

5. Maintenance

The FUR-IF-NMEA2K2 converter is designed for minimal maintenance. Regular checks can help ensure long-term reliability.

Periodic Inspection: Annually inspect all cable connections for corrosion or damage. Ensure connections are tight.
Cleaning: If necessary, gently wipe the unit with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
Software Updates: Check the FURUNO website periodically for any firmware updates for the converter. Follow specific instructions provided with any updates.

6. Troubleshooting

If you experience issues with the converter, refer to the following troubleshooting guide before contacting support.

Problem	Possible Cause	Solution
No data on NMEA 2000 network from NMEA 0183 device.	No power to converter. Incorrect NMEA 0183 wiring. NMEA 0183 device not transmitting. High-speed mode incorrect.	Verify NMEA 2000 network power. Check NMEA 0183 input wiring (Rx/Tx/Ground). Confirm NMEA 0183 device is operational. Ensure high-speed mode setting (orange wire) matches data type.
No data on NMEA 0183 device from NMEA 2000 network.	Incorrect NMEA 0183 wiring. NMEA 2000 network not transmitting relevant PGNs.	Check NMEA 0183 output wiring (Tx/Rx/Ground). Verify NMEA 2000 network is active and broadcasting required data.
Intermittent data loss.	Loose connections. Electrical interference.	Inspect and secure all connections. Relocate the converter away from sources of interference if possible.
