Ideal for sailboats and cruising motorboats, it transmits and receives AIS data to prevent collisions. Unlike 5W SOTDMA (Class B+) models like the V3100 in the same range, this model transmits at 2W (33 dBm) using CSTDMA technology, positioning it as a proven standard solution, perfectly suited for classic coastal and offshore navigation while conserving battery power.\u003c\/p\u003e\n\u003ch3\u003eNMEA 2000 and Dual NMEA 0183 Connectivity\u003c\/h3\u003e\n\u003cp\u003eThis transponder offers maximum installation flexibility for B\u0026amp;G, Simrad, and Lowrance ecosystems. It features an NMEA 2000 port (LEN=1) for direct plug-and-play connection with multifunction displays. For refits or older systems, it includes two independent bidirectional NMEA 0183 ports: a high-speed port (38,400 baud) dedicated to chartplotters, and a low-speed port (4,800 baud) for other instruments. An internal multiplexing function automatically redirects data received on the low-speed port to the high-speed port. A mini-B USB port is also present for initial configuration via PC or Mac with MMSI number assignment.\u003c\/p\u003e\n\u003ch3\u003eRobust Design and Electrical Performance\u003c\/h3\u003e\n\u003cp\u003eDesigned to withstand the harshest marine environments, the NAIS-500's casing is IP67 waterproof and tolerates extreme temperatures from -15 °C to +55 °C. It incorporates a 50-channel internal GPS receiver (IEC 61108-1 compliant) ensuring fast and accurate positioning, requiring an external GPS antenna to be connected to its SMA connector. Its power supply accepts a very wide voltage range from 9.6 V to 31.2 V DC, making it natively compatible with 12V and 24V battery banks. Its power consumption is particularly optimized with an average of only 180 mA at 12V (2 A peak during transmission). A dedicated input on the harness also allows for wiring an external switch to easily activate silent mode (receive only, transmission off).\u003c\/p\u003e","brand":"Navico","offers":[{"title":"Default Title","offer_id":53723745747284,"sku":"000-13611-001","price":776.08,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_366ca238-425f-4251-9132-87b95bd00ef6.jpg?v=1772639560","url":"https:\/\/skysat.fr\/en\/products\/navico-nais-500-ais-transponder-class-b-nmea2000","provider":"Skysat","version":"1.0","type":"link"}
