AIS transponders 800 raidītājs-priņķis

The Garmin AIS 800 is a transceiver transponder. Unlike a simple receiver that only receives signals from other vessels, the AIS 800 receives and transmits your vessel's information. This allows other AIS-equipped vessels to see you on their displays, significantly improving safety and collision avoidance, especially in high-traffic areas or reduced visibility.

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 built-in 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 an integrated 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 you can transmit, the AIS 800 transponder must be programmed with your vessel's specific information, including your MMSI (Maritime Mobile Service Identity), boat name, call sign, and its dimensions. Without this programming, the device will only function in receive mode.

The Garmin AIS 800 transponder has a transmission 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.

Yes, the Garmin AIS 800 has a silent mode (Silent Mode). This mode can be enabled via an external switch (not included) to be connected to the device's wiring. In silent mode, the AIS 800 stops transmitting your boat's information but continues to receive data from other vessels, allowing you to remain discreet while maintaining situational awareness of surrounding traffic.

The Garmin AIS 800 "black box" housing 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, 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 important for calculating the total consumption of your NMEA 2000 network and ensuring that its power supply is sufficient.

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.

Once programmed, the AIS 800 transmits a set of dynamic and static data, including:

Dynamic data: Position (latitude/longitude), speed over ground (SOG), course over ground (COG), rate of turn. Static data: MMSI number, vessel name, call sign, vessel type, vessel dimensions.

Yes, the AIS 800 can be connected to a computer via its USB port. This connection is primarily used for the device's initial programming (MMSI number and other vessel data). It can also be used for diagnostics or to view AIS data on a PC-compatible 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 that lack 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 has a standard NMEA 0183 output that allows it to communicate with most chartplotters on the market, regardless of brand. However, full compatibility (such as controlling transmission or displaying 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 charges. You do not have to pay any fee to use the service, unlike some satellite systems.

Yes, it can be used, but the VHF antenna installation is critical. Carbon masts can disrupt radio signal reception and transmission. 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 location.

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 data with the radio, such as position for DSC (Digital Selective Calling). However, it does not replace a VHF radio and does not allow 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 is supplied with 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 the 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.

Installing the Garmin AIS 800 is within the reach of a skilled DIYer, especially if you are familiar with marine electrical systems. The NMEA 2000 connections are straightforward (T-connections). However, the NMEA 0183 connection and antenna installation require careful attention. If you are unsure, it is strongly recommended to hire a professional installer to ensure correct installation, proper sealing of connections, and error-free MMSI programming.
