AIS 800 transponder transmitter-receiver

Le Garmin AIS 800 est un transpondeur émetteur-récepteur. Contrairement à un simple récepteur qui ne fait que recevoir les signaux des autres bateaux, le AIS 800 reçoit et transmet les informations de votre navire. Il permet ainsi aux autres bateaux équipés d'un système AIS de vous voir sur leurs écrans, ce qui améliore considérablement la sécurité et la prévention des abordages, surtout dans les zones de fort trafic ou par visibilité réduite.

The Garmin AIS 800 is an AIS Class B transponder. It is designed for recreational vessels and small commercial craft not subject to SOLAS regulations, offering an excellent balance between performance and cost.

No, not necessarily. One of the key advantages of the Garmin AIS 800 is its integrated VHF antenna splitter. This allows you to use a single VHF antenna for both your VHF radio and AIS transponder, simplifying installation. Additionally, the device has a built-in GPS and a connector to optionally add an external GPS antenna (model GA 38), which is not included.

The AIS 800 offers dual connectivity for easy integration:

NMEA 2000: For a simple and quick "plug-and-play" connection with modern navigation systems.NMEA 0183: To ensure compatibility with older equipment lacking an NMEA 2000 port.This versatility allows it to integrate into most marine electronic installations.

Yes, absolutely. Thanks to its compliance with NMEA 2000 and NMEA 0183 standards, the Garmin AIS 800 is compatible with the vast majority of chartplotters and multifunction displays on the market (Raymarine, Simrad, B&G, Furuno, etc.) that can display AIS targets.

Yes, this is a mandatory step. Before it can transmit, the AIS 800 transponder must be programmed with your vessel’s specific information, including your MMSI (Maritime Mobile Service Identity) number, boat name, call sign, and dimensions. Without this programming, the device will only operate in receive mode.

The Garmin AIS 800 transponder has a transmit power of 5 watts, which complies with the standard for Class B AIS devices.

The Garmin AIS 800 has relatively low power consumption:

On a 12 Vdc system: less than 400 mA on average.On a 24 Vdc system: less than 250 mA on average.

The integrated splitter is designed to minimize signal loss (very low insertion loss). For most recreational boating uses, VHF radio and AIS performance will remain excellent. However, for absolute maximum range, using dedicated and separate antennas remains the technically optimal solution.

Oui, le Garmin AIS 800 dispose d'un mode silencieux (Silent Mode). Ce mode peut être activé via un interrupteur externe (non fourni) à connecter sur le câblage de l'appareil. En mode silencieux, l'AIS 800 cesse de transmettre les informations de votre bateau mais continue de recevoir les données des autres navires, vous permettant de rester discret tout en conservant une vision du trafic environnant.

The Garmin AIS 800 black box is designed to be compact and easy to install. Its dimensions are 175 x 142.3 x 54.5 mm. The weight of the unit alone is approximately 414 grams.

The Garmin AIS 800 transponder has an IPX7 waterproof rating. This means it is protected against accidental immersion in water up to 1 meter deep for 30 minutes.

No, the Garmin AIS 800 package does not include an external GPS antenna. The unit has an integrated GPS and a connector to add an external antenna (such as the GA 38) as an option.

Yes, the initial programming can be performed by the user. It requires connecting the AIS 800 to a PC via a USB cable (usually supplied) and using Garmin's configuration software. Note: the MMSI number can only be entered once. If an error occurs, the device must be returned to an authorized dealer for reset.

The Garmin AIS 800 has a Load Equivalency Number (LEN) of 2. This information is critical for calculating the total consumption of your NMEA 2000 network and ensuring its power supply is adequate.

The AIS 800 transponder is compatible with 12 Vdc and 24 Vdc electrical systems, allowing it to be installed on most recreational boats and small commercial vessels.

Une fois programmé, l'AIS 800 transmet un ensemble de données dynamiques et statiques, incluant :

Données dynamiques : Position (latitude/longitude), vitesse sur le fond (SOG), route sur le fond (COG), vitesse de giration.Données statiques : Numéro MMSI, nom du navire, indicatif d'appel, type de navire, dimensions du navire.

Yes, the AIS 800 can be connected to a computer via its USB port. This connection is primarily used for initial programming of the device (MMSI number and other vessel data). It can also be used for diagnostics or to view AIS data on compatible PC navigation software.

The AIS 800 unit should be installed in a dry, well-ventilated location, protected from direct water spray and extreme temperatures. Avoid placing it near sources of electromagnetic interference such as magnetic compasses, power cables, or large metal objects.

Yes, the Garmin AIS 800 is designed to be compatible with a wide range of Garmin chartplotters, including older models such as the GPSMAP 7x2, 8x2, and 10x2 series. Thanks to its dual NMEA 2000 and NMEA 0183 connectivity, it can integrate with older systems lacking an NMEA 2000 port. Simply connect it via the NMEA 0183 port on your chartplotter to receive and display AIS data.

Yes, this is possible. The Garmin AIS 800 features a standard NMEA 0183 output that allows it to communicate with most chartplotters on the market, regardless of brand. However, full compatibility (such as control of transmission or display of specific menus) is only guaranteed with Garmin chartplotters. For integration with another brand, you will generally need to connect the NMEA 0183 wires (TX+ and TX-) to the NMEA inputs of your chartplotter. Check your chartplotter's manual for wiring specifications.

No, the Garmin AIS 800 does not require any subscription. AIS (Automatic Identification System) is a free system. Once the device is installed and configured with your MMSI, it transmits and receives AIS data without additional fees. You do not need to pay any usage fee, unlike some satellite systems.

Yes, it can be used, but the installation of the VHF antenna is critical. Carbon masts can disrupt the reception and transmission of radio signals. It is recommended to install the AIS antenna at the top of the mast, ideally with a suitable ground plane. If the mast is carbon, you may need to use an antenna with an integrated ground plane or a dedicated antenna to avoid interference. Consult a professional installer to optimize the placement.

Yes, the Garmin AIS 800 is designed to work in perfect synergy with Garmin VHF radios, such as the VHF 200 or VHF 300 series. When connected via NMEA 2000, it can share information with the radio, such as position data for DSC (Digital Selective Calling). However, it does not replace a VHF radio and cannot make voice calls. It is a complementary safety device.

Yes, the Garmin AIS 800 is fully compatible with the NMEA 2000 protocol. It comes with a standard NMEA 2000 connection cable (with a T-connector). This allows for easy integration into an existing NMEA 2000 network. It can then share AIS data with all devices connected to the network, such as chartplotters, navigation instruments, and autopilots.

Yes, the Garmin AIS 800 comes with a metal mounting bracket. This bracket allows the unit to be securely attached to a flat surface, such as a bulkhead or panel. It is designed for indoor installation on the boat. The bracket includes the necessary screws. Choose a location that is accessible for connections but protected from water spray.

Yes, the Garmin AIS 800 can be used with an autopilot, but indirectly. It transmits AIS data (position, heading, speed) to the NMEA 2000 network. If your autopilot is connected to this network, it can use this information to, for example, automatically avoid collisions (if this function is supported by the autopilot). However, the transponder itself has no direct control function over the autopilot.

Yes, the Garmin AIS 800 is compatible with proximity alarm systems (such as AIS SART or collision alarms). When connected to a compatible Garmin chartplotter, the chartplotter can analyze received AIS data and trigger visual and audible alarms if another vessel is at a dangerous distance or trajectory. This feature significantly enhances safety, especially in low-visibility conditions.

L'installation du Garmin AIS 800 est à la portée d'un bricoleur averti, surtout si vous êtes familier avec les systèmes électriques marins. Les connexions NMEA 2000 sont simples (branchements en T). Cependant, pour la connexion NMEA 0183 et l'antenne, il faut être minutieux. Si vous n'êtes pas sûr de vous, il est fortement recommandé de faire appel à un installateur professionnel pour garantir une installation correcte, une bonne étanchéité des connexions et une programmation MMSI sans erreur.
