[Introduction]：E810-U41S est un module de conversion USB vers RS485 4 voies de qualité industrielle. La coque adopte un revêtement à trois niveaux : antifongique, anti-humidité et anti-sel.Une interface USB externe peut être connectée à 4 interfaces RS485 indépendantes sans s'affecter mutuellement. Convient aux scénarios où l'ordinateur est connecté à plusieurs réseaux RS485 en même temps. Circuit de commutation automatique de l'émetteur-récepteur RS485 intégré, commutation de contrôle de broche indépendante, rendant la communication RS485 plus fiable. Le module est un convertisseur d'interface USB-RS485 universel, qui peut convertir des signaux USB asymétriques en signaux RS-485 sans alimentation externe.
