AIS FA70 Class B+

The main difference lies in the technology and power output. The FA70 uses SOTDMA (Self-Organising Time Division Multiple Access) technology and has a transmit power of 5W. A standard AIS Class B uses CS-TDMA technology with a power output of 2W.

Thanks to SOTDMA technology and its higher power, the FA70 transmits your position more frequently and reliably, even in high-traffic areas, by reserving transmission slots to avoid conflicts.

No, it is not necessary. The FA70 AIS transponder is equipped with an integrated VHF antenna splitter. This allows it to share the same antenna as your VHF radio without performance loss, greatly simplifying installation.

Yes, absolutely. The FA70 is equipped with an NMEA 2000 port, allowing simple and direct integration with multifunction displays and other compatible devices on your NMEA 2000 network.

The device is designed to operate on a 12V or 24V DC electrical system. The accepted voltage range is 9.6V to 31.2V DC.

Yes, the FA70 offers excellent compatibility with NMEA 0183 systems. It includes:

2 NMEA 0183 input ports
2 NMEA 0183 output ports

The output power is selectable depending on the technology used:

5W or 1W in SOTDMA mode (Class B+)
2W in CSTDMA mode (standard Class B)

Warning: the MMSI number can only be entered once. Once saved, it cannot be modified by the user. If a change is required, you must contact your dealer or a qualified technician.

The FA70 transponder housing has an IP55 protection rating. This means it is protected against low-pressure water jets coming from any direction.

Power consumption varies depending on your system voltage and operating mode:

Transmitting (TX): 1.8 A at 12V, or 0.9 A at 24V.Receiving (RX): 0.3 A at 12V, or 0.2 A at 24V.

Yes, it is equipped with a silent mode. This mode allows you to stop transmitting your vessel's position while still receiving AIS data from other boats. It can be activated either via an external switch (optional) or through a software command.

The FA70 transponder has the following dimensions: 177 mm x 158 mm x 55 mm. Its weight is 0.52 kg, excluding cables.

Yes, the FA70 can be configured via a PC. The device features a micro-USB port for this purpose and is supplied with a CD-ROM containing the "AIS Setting Tool" configuration software.

Yes, the GPS antenna is included in the standard supply. The supplied models are the GPA-017S or GPA-C01.

Yes, the FA70 includes an internal GPS receiver. It is a 12-channel receiver, SBAS-compatible, providing fast and accurate position acquisition.

The internal GPS receiver provides a position accuracy of 13 meters (2 drms, HDOP less than or equal to 4).

The unit should be installed in a dry location, protected from direct water spray and rain. The location must be away from heat sources such as exhaust pipes and should have moderate, stable temperature and humidity.

No, it's the opposite. The NMEA2000 network to which you connect the FA70 must have its own external power supply (12–24 V DC). The FA70 does not power the network.

The "AIS Setting Tool" software is compatible with the following operating systems:

Microsoft® Windows® 7 (32-bit / 64-bit)Microsoft® Windows® 10 (64-bit)
