[Introduction]：Le terminal de positionnement par satellite EWD108-GN03B(232) prend en charge le système de positionnement BDS et offre une réponse rapide et un positionnement précis. Il transmet les informations de positionnement via le protocole Modbus RTU, prenant en charge la sortie de chaînes RMC-ASCII conformes au protocole NMEA0183 et des registres séparés pour le stockage (longitude, direction de la longitude, latitude, direction de la latitude, etc.). Le débit de transmission du port série peut atteindre 115 200 bps et est facilement configurable via le protocole Modbus RTU. Le produit est recouvert d'un revêtement protecteur lui conférant une protection contre les moisissures, l'humidité et les embruns salins.
