Furuno FA40 AIS Receiver

Description

Add receive-only AIS traffic data to a Furuno navigation network with the Furuno FA40 AIS Receiver. Its dual-channel receiver monitors both AIS frequencies at the same time and sends received vessel data through NMEA 2000 or NMEA 0183, making it useful for chartplotters and radar displays that need AIS target overlays without transmitting the boat’s own position. Need basic AIS awareness without the registration requirements of a transponder? The FA40 provides low-power below-deck operation with status LEDs and a compact surface-mount enclosure.

Key Specifications

• Furuno FA40 dual-channel dedicated AIS receiver.
• Receive-only AIS device; it does not transmit vessel identity, position, or voyage data.
• Simultaneously monitors AIS frequencies from 156.025–162.025 MHz.
• NMEA 2000 and NMEA 0183 output ports.
• No built-in GPS receiver; an external GPS source may be required by the connected display.
• Status LED indicators; no onboard AIS target display.
• 12V/24V DC operating input with up to approximately 2W maximum power consumption.
• IPX2 enclosure for protected helm or cabin installation.
• Operating range of 5°F to 131°F (-15°C to 55°C).
• Approximate dimensions: 5.9 × 4.7 × 2.0 inches; approximate weight: 0.88 lb (0.4 kg).
• Bulkhead or flat-surface mounting.

Integration

The FA40 requires a suitable AIS/VHF antenna or approved splitter and a compatible chartplotter, MFD, radar display, or navigation computer. It is not an AIS transceiver, VHF voice radio, GPS receiver, radar, chartplotter, or emergency beacon. Because it is receive-only, it will not make the vessel visible to other AIS-equipped traffic.

AIS reception depends on antenna height, coaxial cable condition, local radio interference, terrain, weather, and other vessels transmitting valid data. AIS does not show every vessel, floating object, buoy, or navigation hazard and should supplement—not replace—radar, charts, visual lookout, and safe navigation practices.

Installation Notes

Mount the receiver in a dry, accessible, protected location. Use a proper AIS/VHF antenna or approved splitter, route RF cables away from high-current wiring, and connect NMEA 2000 or NMEA 0183 to the appropriate input on the receiving display. Confirm the display is configured to receive AIS data at the correct data rate.

Use correctly protected 12V/24V power and check the unit’s status LEDs after installation. Test target reception before regular use and inspect antenna, coaxial, power, and data connections routinely.

Before Ordering

Confirm Furuno display compatibility, available NMEA 2000/NMEA 0183 input, AIS antenna or splitter requirements, dry mounting location, 12V/24V power availability, and whether receive-only AIS meets the vessel’s operating needs before ordering.
