Detailed description

The Navico NAIS-500 Class B AIS transponder, supplied with its GPS-500 antenna, is a compact and high-performance solution for enhancing safety at sea. This standalone Class B system transmits your vessel’s identity and position data while receiving that of other AIS-equipped vessels, enabling better anti-collision maneuver planning in high-traffic areas. Positioned as an economical alternative to Class A systems, the NAIS-500 is ideal for recreational boats and small commercial vessels, offering transmission power and reporting rate tailored to their specific needs.

Connectivity and System Integration

The NAIS-500 features versatile connectivity, integrating NMEA 2000 (LEN=1), two NMEA 0183 ports (one high-speed at 38,400 baud for chartplotters and one low-speed at 4,800 baud for other equipment), and a USB port (mini-B) for connection to a PC or Mac. This flexibility ensures seamless integration with Navico ecosystems, including Simrad multifunction displays (NSS, NSO, GO series), Lowrance (HDS Carbon, HDS Gen3), and B&G (Vulcan, Zeus series). The integrated NMEA 0183 multiplexing function optimizes data management across serial ports. The transponder is supplied with a multipole accessory cable for power (9.6 V – 31.2 V DC) and NMEA 0183 connections, as well as an input for an external silent-mode switch. A VHF antenna (SO-239 connector) and an external GPS antenna (SMA connector) are required, with the GPS-500 antenna included.

Technical Specifications and Robustness

Measuring 152 x 98 x 52 mm and weighing 260 g, the NAIS-500 is designed for discreet installation. It operates on a frequency range of 156.025 to 162.025 MHz with an output power of 33 dBm ± 1.5 dB. Its internal 50-channel GPS receiver complies with IEC 61108-1, ensuring reliable position acquisition. Average power consumption is 180 mA at 12 V DC, with a peak current of 2 A. Certified to IP67 and tested to IEC 60945 (Protected category), it provides optimal resistance to marine environments, supporting operating temperatures from -15°C to +55°C. LED indicators (power, error, reception, transmission/silent mode) offer quick diagnostics of the device’s status. The NAIS-500 complies with CE, FCC, Industry Canada, IEC 61108-1, and IEC 60945 certifications.

What is a Class B AIS transponder like the NAIS-500?

The Navico NAIS-500 Class B AIS transponder is a standalone system designed to enhance safety at sea. It transmits your vessel’s identity and position data while receiving that of other AIS-equipped boats. This enables better anticollision maneuver planning, particularly in high-traffic areas. It is a compact and high-performance solution, ideal for recreational vessels and small commercial craft.

What is the difference between an AIS Class A and Class B transponder?

AIS Class B transponders are similar to Class A transponders in many ways, but they are generally less expensive due to less stringent performance requirements. Class B transponders transmit at a lower power and a lower communication rate than Class A units. The NAIS-500 is a Class B transponder.

What are the dimensions and weight of the NAIS-500 transponder?

The NAIS-500 transponder has dimensions of 152 x 98 x 52 mm (length x width x height) and weighs 260 grams.

Is the NAIS-500 waterproof?

Yes, the NAIS-500 transponder is waterproof and has an IP67 protection rating, meaning it is protected against temporary immersion in water.

What is the operating temperature range of the NAIS-500?

The NAIS-500 transponder is designed to operate within an ambient temperature range of -15°C to +55°C.

What is the power consumption of the NAIS-500 transponder?

The NAIS-500 transponder has an average current draw of 180 mA at 12 V DC and a peak nominal current of 2 A at 12 V DC.

Does the NAIS-500 include a GPS receiver?

Yes, the NAIS-500 comes with a GPS-500 antenna and includes an internal 50-channel GPS receiver compliant with IEC 61108-1.

What is the transmission power of the NAIS-500?

The NAIS-500 transponder’s transmit output power is 33 dBm ± 1.5 dB.

What data does the NAIS-500 transmit?

As a Class B AIS transponder, the NAIS-500 transmits your vessel's identity and position data, enabling other AIS-equipped vessels to locate you and anticipate maneuvers.

How to check if the NAIS-500 is functioning correctly?

The NAIS-500 is equipped with four LED indicators to signal its operating status:

PWR (Solid green): The device is powered on and operating normally.ERR (Solid or flashing red): Indicates a system error or an unprogrammed/invalid MMSI.Rx (Flashing green): The device is receiving AIS data.Tx (Solid orange): AIS transmission is disabled (silent mode).

What does the red ERR LED indicate on the NAIS-500?

The red ERR light on the NAIS-500 can indicate two situations:

Solid red: The MMSI identification is not correctly programmed.Flashing red: The transceiver has detected a system error. This state is also associated with the USB connection, only during initial programming.

Can the NAIS-500 be set to silent mode?

Yes, the NAIS-500 can be set to silent mode. An external switch can be connected to activate this function, which is indicated by the solid orange Tx LED. In silent mode, no AIS transmissions are sent.

What are the power supply requirements for the NAIS-500?

The NAIS-500 requires a DC power supply (direct current) between 9.6 V and 31.2 V. The included accessory cable provides power connections (red wire for positive, black wire for negative).

What types of cables are provided with the NAIS-500 for installation?

A multipolar accessory cable is supplied with the NAIS-500. This cable has a preformed connector at one end for the unit and eight stripped wires at the other end for connections to the power supply, the external silent mode switch, and the NMEA 0183 data ports.

How to connect the external GPS antenna to the NAIS-500?

The GPS antenna cable must be connected to the GPS connector of the AIS transceiver/receiver. The NAIS-500 has an external GPS antenna connector of SMA type.

How to connect the VHF antenna to the NAIS-500?

The NAIS-500 is equipped with a VHF antenna connector of type SO-239. A compatible VHF antenna must be connected to this port for the transponder to function.

Is a specific clearance area required around the transponder during installation?

Yes, it is important to allow sufficient space around the AIS transceiver for cable routing and clearance. Additionally, the ambient temperature around the device must be maintained between -15°C and +55°C.

What data connection types does the NAIS-500 offer?

The NAIS-500 provides versatile connectivity, including:

One NMEA 2000 port (LEN=1). Two independent NMEA 0183 data ports: one high-speed port (38,400 baud) primarily for chartplotters, and one low-speed port (4,800 baud) for other NMEA 0183 devices. One USB port (mini-B) for connection to a PC or Mac.

Is the NAIS-500 compatible with Navico multifunction displays (Simrad, Lowrance, B&G)?

Yes, the NAIS-500 is designed for seamless integration with Navico ecosystems. It is compatible with Simrad multifunction displays (NSS, NSO, GO series), Lowrance (HDS Carbon, HDS Gen3) and B&G (Vulcan, Zeus series) thanks to its NMEA 2000 and NMEA 0183 interfaces.
