Detailed description

NAIS-500 frá Navico er AIS-útsendingarstöð af flokki B, mjög þétt og létt (260 g), hönnuð til að passa fullkomlega inn í nútíma siglingakerfi. Hentar vel fyrir seglbáta og skemmtiferðaskip, og tryggir sendingu og móttöku AIS-gagna til að fyrirbyggja árekstra. Aftur á móti, ólíkt SOTDMA-líkönum (flokkur B+) með 5W útgangi eins og V3100 í sömu seríunni, sendir þetta líkan út á 2W (33 dBm) með CSTDMA-tækni, sem gerir það að staðlaðri og traustri lausn sem hentar fyrir venjulega strand- og langferðasiglingar og sparar rafhlöðurnar.

NMEA 2000 og tvö NMEA 0183 tengingar

Þessi útsendingarstöð veitir mestu sveigjanleika við uppsetningu fyrir B&G, Simrad og Lowrance kerfi. Hún hefur NMEA 2000 port (LEN=1) fyrir einfaldlega "plug and play" tengingu við fjölnota skjáir. Fyrir endurbætur eða eldri kerfi hefur hún tvö sjálfstæð NMEA 0183 port í báðar áttir: eitt hraðaport (38 400 baud) fyrir sporgögn, og eitt hægfara port (4 800 baud) fyrir önnur tæki. Innri margfeldisvörpun sendir sjálfkrafa móttökuð gögn frá hægfara portinu yfir á hraðaportið. Einnig er til staðar USB mini-B port fyrir upphaflega stillingar með PC eða Mac ásamt úthlutun númeris MMSI.

Robust hönnun og rafmagnsgeta

Hönnuð til að standa við erfiðustu hafarhverfi hefur NAIS-500 einangrun IP67 og þolir öfga hitastig frá -15 °C upp í +55 °C. Hún hefur innbyggðan 50-ganga GPS móttöku (samkvæmt IEC 61108-1) sem tryggir nákvæma og fljótlega staðsetningu, og krefst tengingar við ytri GPS-óntöku á SMA tengi. Rafmagnsviðtaki hennar tekur mjög breiða spennuspennu frá 9,6 V upp í 31,2 V DC, sem gerir hana samhæfa með 12V og 24V rafhlaðasamsetningum. Rafmagnsneysla hennar er sérlega skilvirkt með aðeins 180 mA meðalnotkun við 12V (toppur upp í 2 A við sendingu). Sérstakt inntak á rafmagnskerfinu gerir einnig kleift að tengja við ytri rofa til að auðveldlega kveikja á kyrrstöðuham (einungis móttaka, sendingu slökkt).

« A low-power AIS transponder with NMEA multiplexing »

The Navico NAIS-500 AIS transponder is a reliable choice for integration within the group's ecosystems (B&G, Simrad, Lowrance). Its main technical advantage lies in its highly comprehensive communication architecture: the simultaneous presence of NMEA 2000 and a dual NMEA 0183 port with integrated multiplexing greatly simplifies complex refits where older instruments must coexist with latest-generation multifunction displays. Although it is a standard Class B AIS (CSTDMA) transmitting at 2W, unlike the newer 5W SOTDMA models on the market, its very low average power consumption of 180 mA makes it a strategic choice for sailboats concerned with their overall energy balance. Its IP67 housing and wide voltage tolerance range (9.6 to 31.2 V) ensure excellent electrical reliability. Caution during installation: the device absolutely requires a dedicated GPS antenna via its SMA port and a VHF antenna (or an active splitter) via its SO-239 port to operate.

Frequently asked questions

Need help? Contact us

What is a Class B AIS transponder?

A Class B AIS (Automatic Identification System) transponder is a safety device that transmits your vessel's identity, position, heading, and speed to other ships equipped with an AIS receiver. Designed primarily for recreational boating, it has lower transmission power and update frequency than Class A devices (mandatory on commercial vessels), while still providing essential visibility to avoid collisions.

What are the connectivity options for the NAIS-500?

The NAIS-500 offers comprehensive connectivity to integrate with most navigation systems:

NMEA 2000: For simple and fast connection to modern networks and multifunction displays.NMEA 0183: It features two independent ports. A high-speed port (38,400 baud) for chartplotters and a low-speed port (4,800 baud) for other instruments.USB: A mini-B port allows connection to a PC or Mac, primarily for initial device configuration (MMSI number programming).

What input voltage is required to operate the NAIS-500?

The NAIS-500 transponder is designed to operate on a direct current (DC) supply ranging from 9.6 V to 31.2 V. It is therefore compatible with standard 12 V and 24 V vessel electrical systems.

Is the NAIS-500 housing waterproof?

Yes, the NAIS-500 is designed for the marine environment. It has an IP67 rating, meaning it is fully protected against dust and can withstand temporary immersion in water up to 1 meter deep.

How can I connect the NAIS-500 to my Simrad, Lowrance or B&G multifunction display?

The simplest and recommended method to connect the NAIS-500 to a modern multifunction display (Simrad, Lowrance, B&G) is to use the NMEA 2000 network. The device features a standard NMEA 2000 connector for plug-and-play integration. For older equipment, connection can be made via the high-speed NMEA 0183 port (38,400 baud).

Does the NAIS-500 integrate its own GPS receiver?

Yes, the NAIS-500 is equipped with an internal 50-channel GPS receiver compliant with IEC 61108-1. This allows it to obtain its own position autonomously for transmission via AIS.

Do I need to install an external GPS antenna?

Although the NAIS-500 has an internal GPS receiver, it also features an SMA connector for an external GPS antenna. Using an external antenna is recommended if the device is installed in a location where GPS signal reception is obstructed (for example, inside a metal hull or without an unobstructed view of the sky).

What is the power consumption of the NAIS-500?

The NAIS-500's power consumption is optimized for onboard use. On average, it is 180 mA at a 12 V DC supply. During transmission, consumption can peak at 2 A.

How does silent mode work and how do I activate it?

Silent mode stops your vessel from transmitting AIS data while still receiving AIS data from other boats. To activate it, connect an external switch (not supplied) to the dedicated wires (Orange and Light Green) on the power and data cable. When the switch is closed, the 'Tx' LED lights up orange and the device switches to silent mode.

Which types of antenna connectors are required?

The NAIS-500 uses standard connectors:

For the VHF antenna, it has an SO-239 connector (female UHF). For the optional external GPS antenna, it uses an SMA connector.

Can I use this device with a computer?

Yes, the NAIS-500 can be connected to a PC or Mac via its USB mini-B port. This connection is primarily used for the initial setup of the device, particularly to program your MMSI number and your boat's static information using the provided software.

What is the transmission power of the NAIS-500?

As an AIS Class B transponder, the NAIS-500 has an output power of 33 dBm ± 1.5 dB, which corresponds to approximately 2 Watts.

What do the different LEDs on the device indicate?

The NAIS-500 has four LED indicators that display its operational status:

PWR (Green) – Solid on: device is properly powered.ERR (Red) – Solid on: indicates an error, often an invalid or unprogrammed MMSI number. Flashing: indicates a system error.Rx (Green) – Flashes to indicate reception of AIS data from other vessels.Tx (Orange) – Solid on: indicates silent mode is active and the device is not transmitting its position.

Does the AIS require a dedicated VHF antenna?

Yes, for optimal performance and to comply with regulations, the AIS must use its own VHF antenna. Alternatively, you can use a certified AIS antenna splitter, which allows you to share the main VHF antenna of your radio with the NAIS-500 transponder.

How is the wiring done for power and NMEA 0183 data?

The NAIS-500 comes with an accessory cable that plugs into the 'PWR/0183' port. The other end of this cable has stripped wires with color coding to simplify connections: red and black for power, and additional pairs of colored wires for the two NMEA 0183 ports (input/output) and for the silent mode switch.

Is the NAIS-500 compatible with older NMEA 0183 navigation instruments?

Yes, absolutely. The NAIS-500 is equipped with a low-speed NMEA 0183 port (4 800 baud) specifically designed to be compatible with older instruments using this standard, in addition to its high-speed port for modern chartplotters.

What is the NMEA 0183 multiplexing function?

The NAIS-500 features an integrated multiplexing function. This means that NMEA 0183 data received on its low-speed input port (e.g., from a wind transducer or depth sounder) is automatically combined with AIS data and retransmitted via the high-speed output port to your chartplotter. This simplifies wiring by eliminating the need for an external multiplexer.

How do I program my MMSI number in the device?

The MMSI (Maritime Mobile Service Identity) number and other vessel information (name, type, dimensions) must be programmed during the initial installation. This is done by connecting the NAIS-500 to a PC or Mac via the USB port and using the appropriate configuration software. It is critical that this information is correct because, for safety reasons, it can generally only be modified by an authorized technician after the initial programming.
