[Introduction]：Le NB144-V2 est un serveur série 4 ports de deuxième génération développé par Ebyte. Il intègre une pile de protocoles TCP/IP, permettant la transmission bidirectionnelle transparente de données série vers Ethernet, la conversion de protocoles Modbus et la connectivité cloud des périphériques série. Prenant en charge la configuration des ordinateurs hôtes, il est largement utilisé dans des secteurs tels que la surveillance des salles informatiques et la surveillance environnementale. Il est doté d'un revêtement conforme, offrant des propriétés anti-moisissure, anti-humidité et anti-brouillard salin.
