[Introduction]：Le NB124ES-V2 est un serveur série double port de deuxième génération développé par Ebyte. Il intègre une pile de protocoles TCP/IP et permet la transmission bidirectionnelle et transparente de données série vers Ethernet, la conversion de protocole Modbus et la connectivité cloud des périphériques série. Il prend en charge la configuration de l'ordinateur hôte, facilitant ainsi la mise en réseau et la connectivité cloud des périphériques série. Il est largement utilisé dans des secteurs tels que la surveillance des salles informatiques, la surveillance environnementale, le transport intelligent, le contrôle des portails et les casiers express intelligents. Il est doté d'un revêtement conforme pour une résistance à la moisissure, à l'humidité et au brouillard salin.
